Wiring Your House and a Three-Way Switch

!±8± Wiring Your House and a Three-Way Switch

Building a house takes a lot of planning and a lot of though put into the little details. Where you put your electric outlets and switches may not seem that important, but when you start placing furniture and plugging in lamps and other electronics, it will. Taking the time to plan the wiring of a house always pays off in the long run.

If you aren't sure where everything is going to go in the house the best thing to do is place an outlet on every wall. Wiring you house this way will allow for a lot of flexibility on where you place your furniture. Also placing all the outlets a foot off the floor will make them easy to access. Switches are best placed where you enter a room so that you can turn on a light as you come in and you won't be stumbling around in the dark.

You need to determine where fixed lighting will go next. Canned lighting is appropriate for areas such as the kitchen and family room. It is best to put canned lighting on a dimmer switch since they can sometimes seem too bright. Ceiling fans with a light fixture are another option to consider. There is a wide variety to choose from and a fan is nice for a light breeze on a warm night.

Once you have made all the decisions on outlets, switches and fixtures it is best to draw out a plan for each room to be wired. Then you can easily make a list of materials that you will need.

This is also the time to decide if you would like any three-way switches installed. They can be useful for rooms that have two entrances, so that you can turn on and off the lights from either side.

The only real difference in a regular switch and a three-way switch is that the two switches on the opposite sides of the room are hooked together with what is called a traveler wire. You will have one end of the traveler wire pulled through both boxes at each entrance of the room. Then it is just a matter of twisting the wires from the traveler with the regular wires, by matching up the colors and then wiring the switch normally. When you look at the switch the only difference is that it will have double wiring on one side.

Once your planning is done and all your materials bought you can get started wiring your house.

Please remember though to make sure the power is off before you start.

Solar Power Math Problems - Part I, Calculating Solar Panel Circuits

!±8± Solar Power Math Problems - Part I, Calculating Solar Panel Circuits

Math problems are everywhere when solar power is concerned, not only for reducing power losses, but also for safety considerations. Article 690 of the National Electrical Code (NEC) requires derating and correction factors based on the type of wiring involved and the locations the wires are installed. There's also a default "just because it's solar" calculation with a lot of good reasons related to the NEC's goal of life safety. I installed my system using the 2003 edition, which was the current edition at the time.

The first math problem deals with solar panel output. When planning your solar panel installation, technical details for stuff Pmax, Vpm, Ipm, VOC, and Isc are needed for a safe design. Here are the specs for the solar panels I used:

Sanyo HIP-180: Pmax 180 watts, Vpm 54.0 volts, Ipm 3.33 amps,  Voc 66.4 volts, Isc 3.65 amps BP Millenia MST-43MV:Pmax 43 watts, Vpm 72.0 volts, Ipm 0.6 amps, Voc 98 volts, Isc 0.8 amps

The NEC requires a 'weather correction factor' to determine the highest possible voltage. Solar panels produce less power the hotter they get; they produce more power the colder they get. The NEC has a table (Table 690.7, Voltage Correction Factors for Crystalline and Multicrystalline Silicon Modules) that gives the correction factor, based on the coldest possible operating temperatures expected.

From the 2008 version of the NEC: [NEC 690.7]

-11C to -15C (13F to 5): 1.16 -6C to -10C (22F to 14F): 1.14 -1C to -5C (31F to 23F): 1.12

My area's coldest daytime winter temperature is usually above 22F so my weather correction factor would be 1.14, but I've seen 30 mph winds on bright sunny winter days, so I'll use the higher number to allow for windchill.

Each group of panels is a 'PV Source Circuit'. My panels are wired in parallel (two per circuit); the math runs like this: [NEC 690.8(A)(1)]

the sum of all the Isc numbers in the circuit, multiplied by the weather correction factor equals the 'PV Source Circuit Current' 3.65A + 3.65A = 7.3A times 1.16 = 8.468A

The PV Source Circuit Current is then multiplied "because it's solar" by 1.25. 8.468A times 1.25 = 10.585A. This is the maximum possible current that each circuit could possibly produce. If I selected only a 10 amp fuse for this circuit, there is a strong possibility I'd have to replace fuses pretty often in the winter time, especially on bright sunny days with lots of snow reflecting even more light onto the solar panels. [NEC 690.8(B)(1)]

Now that I've determined how much current might be produced, I need to select the correct wire size. I'm using type USE-2 cable from the solar panels to the combiner box where the circuit breakers are located. USE-2 cable is UL listed for outdoor use in hot areas (90C) and is also sunlight resistant. The temperature derating of USE-2 in 141-158F is 0.58 [NEC 310.16]

Ampacity of USE-2 cable, 10AWG: 40 amps 40 amps times 0.58 = 23.2 amps Ampacity of USE-2 cable, 12AWG: 30 amps 30 amps times 0.58 = 17.4 amps Ampacity of USE-2 cable, 14AWG: 25 amps 25 amps times 0.58 = 14.5 amps

The wire size has to be able to handle 125% of the derated PV Source Circuit Current (10.585A), so 10.585A times 1.25 = 13.23A. Our wire has to be thick enough to handle 13.3 amps, so either of these sizes would meet the electrical code.

Temperature derating for multiple cables. There is an additional factor to be aware of if these wires are running through conduit. Based on the number of current carrying conductors (positive conductors), the wire is derated according to the following: [NEC 310.15(B)(2)(A)]

4-6 conductors: 80% 7-9 conductors: 70% 10-20 conductors: 50%

If these 10 these circuits are running through conduit, then the rating for 10AWG (40A > 23.2A) is reduced yet again. 23.2 times 0.5 = 11.6 amps. I can either run 9 circuits in conduit and run 1 circuit free (allowed with USE-2 cable) and derate the circuits in conduit to 70% (16.24A), or divide the runs, with 5 circuits per conduit and derated to 80% (18.56A).

Flatbed Scanner Lamp into an Emergency Lamp

EDIT PLEASE READ!! This has been updated. I have added an old switch in line with the 12VDC power and this rig is hanging on my wall as an emergency light and runs off a digital photo frame external battery that I bought at walmart for 15 bucks. the battery is plugged in all the time so if the power does go out I still have bright light. I may post an update vid to this. Inspired by Kipkay's flatbed scanner hack video where he made a desk lamp from the guts of an old flatbed scanner. As seen on instructables. www.instructables.com Kipkay's Flatbed Scanner Hack Video www.youtube.com Found the correct voltage of my inverter here. 12VDC 500mA silenceisdefeat.com I plan to add a switch on mine, I kept the case that holds the light b/c it's very fragile and I didnt want it breaking. I insulated all the wires with good old electrical tape. Hope you like this one.

Three Operations Of Deburring Equipment

!±8± Three Operations Of Deburring Equipment

There are numerous techniques of deburring, but most can be assessed into different types. Every single deburring process makes use of deburring machine to complete the task.

Even the most basic type of deburring, manual deburring, makes use of machines in order to finish the job. Manual deburring equipment is often preferred over other kinds of deburring because it is affordable. Although, as it is manual it requires a human being's personal focus on the material or object used. Additionally, it provides flexibility wherein other kinds of deburring machine are not going to. Outlined below are three deburring procedure using deburring equipment.

A thermal deburring procedure is fast in making intense high temperature yet happens to be noted to be the most dangerous deburring method. This type of deburring machine has to be isolated in a unique area which is explosive resistant because the method will release a combination of special gases and oxygen which ignites with an electric spark. No one should be within the room for the duration of this process because it is very harmful and dangerous. As strangely as this might sound but the explosion is exactly what gets the process accomplished. Although, on the bright side, thermal deburring equipment is equipped to burrs areas or spots that are difficult to reach such as small openings, edges as well as other places. It can deburr materials simultaneously.

Cryongenic deburring procedure is the utilization of rubber and plastic material. This process will be the opposite of thermal which in turn produces high temperature, cryogenic produces materials that are frozen through the use of liquid nitrogen, dry ice or perhaps liquid carbon dioxide. The deburring equipment is utilized to maintain these chemicals as safe as possible. When using the machine, the materials will be frozen at a temperature below 300 degrees Fahrenheit. This method makes it much simpler for the burrs to be removed from the materials because the rubber and plastic tend to be long lasting, it benefits the most from this type of deburring method. If this type of method were to be tested out on timber or steel, the whole part is going to simply break.

Electrochemical deburring machine is quite precise and accurate as it makes use of electricity and chemicals to get to the hard spots or location. The best thing about this process is the fact that the remaining material is unsusceptible to the deburring. Using a pinpointed electric current and glycol or salt to achieve its goals, the deburring approach will go on up to ten seconds.

Deburring equipments can be used by 3 procedures which include thermal that generates extreme heat, cryongenic that freezes as well as electrochemical which uses electricity to get rid of the burrs on components. Each one of these procedures are used or unique scenarios when a human or perhaps machine needs to burrs which are found in areas that are difficult to get to. You can assume that cars, motorcycle as well as other manufacturing are please to know that this deburring equipments are in the market today.

Living Within Your Means Or Even Better, Below Your Means!

!±8± Living Within Your Means Or Even Better, Below Your Means!

Why are we in a recession, economic downtrend, or "term of your choosing"? Well, many reasons, but most of it has to do with debt in some form or another. And, the #1 cause behind it whether it be individuals or even our government, is that most of us simply lived bigger than we could afford to & have done so for a very long time! How much better would it be if we lived as many of our relatives of the yesteryears lived; below their means, saving some monies for a "rainy day" or possibly emergencies (ie: the unexpected in whatever form it appears).

What happened in the last 2 to 3 decades that has led us here?

In the 50s and 60s credit cards became more and more the norm and continually increased in popularity. By the 80s people became accustomed to buying when it suited them on their credit cards (whether they could "afford it" or not). They paid the interest to have it all "now". The problem is most of the time it was borrowed against future earnings expected. As life "happened" and the unexpected took place ie: car repairs, lost earnings at work, or unexpected expenses in any form, in addition to the fact that many people hopped around to find the work that suited them, or for whatever the reason, weren't earning as much as they were spending. In many cases that gap between earnings and expenses just kept becoming bigger and bigger until the gap became a canyon. Years of buying vehicles, homes and lots of "stuff" on credit loans and credit cards have caught up with us. Even the U.S. government has a ridiculous amount of debt compared to the 80s. I heard recently that much of the U.S. debt has been underwritten (purchased/invested in) by foreign entities and countries, including a huge portion to the Middle East! That is disturbing to me!

Today, there are scads of news stories about riding bicycles to work, spending less, and living differently. I am convinced that as difficult as the economy is on many of us, whether it be from the affects of lay-offs from companies downsizing or closing down, or homes being lost due to the too big mortgages previously committed to, or the prices up up and away on everything from gas to food, many have had to make some big changes. We as a nation are talking, walking, and spending differently for the most part. For many years most of us have been living week to week. When the economy goes haywire, that wreaks havoc on all that are living too tightly to begin with, or, worse steeped in debt.

I personally believe that if we allow it to, this can be a wake-up call for us as individuals as well as our government leaders. Often people only change when they have no other choice or their concerns outweigh their "live for the moment" mentality. The statistics confirm that many of us are currently not spending as frivolously. And the credit cards I suspect are being used mostly for survival (as a substitute for lack of savings) instead of "stuff". Far less people are buying new vehicles or homes these days. When I see and hear all the huge sales on vehicles and homes and other big ticket items, it reminds me that to be debt free today is a gift of huge proportions. Today can be the day for change, for forethought, for wisdom. I truly hope we all learn from these pivotal times that appears to have enveloped us in the latter months of 2007 and deepened in severity through 2009 thus far. Is it tough... absolutely! But I do believe we all can and need to learn the important lessons and long term benefits of living within and below our means.

All that said, those that may have been thought to be a bit off the societal paths in their thinking and/or possibly laughed at for their frugality and voluntary simplicity (from simple choices to the major off the grid folks) may now get some respect for those choices (if not some envy)! I also believe that those of us who know how to live well in simple ways; for example knowing how to camp and cook simply and even those who have downsized to live in an RV (hopefully paid for) are often ahead of the line in their/our abilities to live well in tough economic times. Suddenly knowing how to live well in a small RV or a van doesn't seem nearly as odd and ludicrous to the societal masses anymore. I am personally, so thankful to be (continually learning) and preparing to van dwell or live as simply as becomes necessary, while still enjoying the comforts that are personally important to me. I think it is a gift to be of that mindset. I feel empowered by the lessons learned by having traveled across the USA a few years ago in a small pick-up camper on my then Dodge Dakota mid-sized truck. I am glad I have been a camper and know how to live more simply if necessary.

I am admittedly a gadget girl, and love my laptop and techy gadgets, and although I confess I would have a hard time without my laptop for very long, I can grill over an open fire, happily pass the time by reading a book, know just enough about using an inverter and emergency power source to get me by when needed, and if I had to I could use a simple porta potty without having a nervous breakdown over it. Those of you who are free thinkers and always enjoyed the freedom of alternative living ideas, I believe are better for it in these times. For those of you who have cringed at the thought of living without your morning cup of coffee, or traveling without staying in a 0 per night hotel, there may be be some relearning and adjustments necessary along the way. But that's OK, you are bright and you can learn to do things more frugally and simpler if need be, right?

Yep, America is changing... then again maybe the bulk of the tough times will soon go away and once again everything will go back to the numbness of spending and going deeper and deeper into debt without much thought. I hope things getter better soon but I hope we don't go back to our living beyond our means and all that has brought us here. I sadly suspect being creatures of habit, that once the immediate pain has subsided many of not most will go right back to their old ways of living far beyond their means. But will you or I? No... not I, I made that choice months ago and thankfully am now debt free. I may not own a home as you do, or a new vehicle, but I have a paid for 97 GMC Safari Van and am doing OK and am very grateful not to have a bunch of debt weighing me down.

The economy is rough in other countries as well, but here in America we have been ripe for this for quite some time now. It is a rude awakening for most of us. Whether it be taking care of our individual households or running companies, things are challenging these days for many of not most of us! But we can learn and live and be ultimately better for the lessons from it.

Living within your means = Good Choice! ~ Living below your means = Wise Choice!!!

Power Supply Tester Review

!±8± Power Supply Tester Review

What is orange has the tail of a serpent, to lose or replace them and respond to 700 CM code name? Simple, it is a modular power meter is now on the test bench.

Once, when I was approached by an examination conducted by various magazines, I can only answer yes and waited patiently for the arrival of the sample site of the power meter. And since the product is a modular power supply tester, a new generation of the waiting period seems like an eternity ... that, up to a coldMorning the courier arrived with the package in his arms ... From here up to now, leave no room for tensions.

Packaging and presentation

The new power meter, the source is in a box the size and shape as those used in this product line. The cap must come from the contrasting colors of the logo of the manufacturer is based, and the name and power (depending on model) to find. On the other hand, we have presented the most important internationalLanguages ​​and also the only image that shows the power cord to a greater or lesser degree. The sides are again the most important features in a little over a graphical representation using the logo, a list of ports, a very useful representation of images and values ​​of the table for the sides rated power bar. If someone wants to know more about power meters, simply turn the container on all sides.

Content

When opening the window will not happen againtwo "ears" when he opened the window a good show. The source is packaged in a plastic bag with the logo printed in white. The package includes the source neighbor, power cord, a small manual and a bag with four screws and a Cougar emblem. The cables are offset with a pattern / color palette that I personally think it looks like a bunch of dangerous serpents ... brr ... Source ... Inspired or dislike (depending on individual taste), and the color orangecertainly attract the eye.

Power Cable Tester Details

Cable length is normal, but I personally prefer a slightly longer length designed for 24-pin power, distance and available in large enclosures with power source to a guide wire is often done poorly or not at full potential . Nothing to blame, but their quality, all clearly ... so that for every newcomer.

External Analysis

Here we have reached a natural source ... and of coursethe first thing that catches the color. The back has a honeycomb, which does not cover the entire surface. From here the power is remarkable and very important ... is in the position through green lights. The back has three slots are on the domestic power cables, current sheets are clearly marked. The logo is imprinted on one side, while the other wore a sticker with the table of separation of powers, series, model and emblem shows 80PLUS Bronze certification tests.

I hope this reviewis good for the new power meters on the market believes. It 's probably the best there is. Well, why not take a look for yourself and be convinced of his greatness?
