Q:I know that the color codes tell you whether its neutral and other purposes, but do i need to find the same colored wire to extend one, or do i need the same one? And are they just for safety purposes?

Colors are not universal. Generally, red and green are power wires, black and white are ground.but not always. Its mostly for safety or for ease of connecting wires. For example, instructions for wiring in something would be confusing as hell if there was no way to tell what wire does what. Most items will come with an manual that say what each colored wire is, and what it does, so you know how to wire everything up correctly. You do not need to use the same color, as long as you can keep everything straight so you do not hook things up wrong. However, you should use the same size of wire.

Q:(Home and a car.) Suggest reasons why different wires are used in different situations.

The previous answer is very correct and covers a variety of applications. What is missing is the selection of a size (or gauge) of wire based on the application. The size of the conductor (wiring) must be adequate to support the electrical load. If you are going to attach an appliance to a power source, the wire must be sized based on the amount of current the appliance will draw. Look at your power cords around the house, some are much heavier, particularly on the refrigerator, laundry, air conditioner, and etc. Same with your car. The battery has to support all the electrical loads so the cables are extra heavy compared with anything else in the car.

Q:I need to melt fishing line with the resistance in an electrical wire powered by a 9 volt battery. how do i go about this safely??

If aluminum wiring is put in wisely and maintained wisely there's no subject. there is probable a unfastened connection at your outlet that the microwave is plugged into. maximum probable somebody replaced that outlet with a CU merely outlet and it would be CU/AL (copper/aluminum) it rather is greater costly. we've aluminum wiring in our domicile and have in no way had a topic. i take advantage of the right merchants and make useful they are stable and tight while changing an outlet, which you will possibly desire to do with copper wiring additionally. So, I propose you examine that outlet and alter it out if needed. shrink off the small area of undesirable twine before changing the opening.

Q:Hey! Im trying to fix a rental property i have and this is the first time ive done any work to it. When i arrived the hallway light was not working. It has a switch at each side of the hall. It has White/Black/Red wires. I tried installing a new light and without touching the wires i tried to install it off the white/Black wires and i couldnt recieve power. I tried messing around and cant seem to figure it out. Is the red wire needed for a simple hallway light? What is it there for? . also maybe related in one of the bedrooms i have an elec outlet plug i replaced and worked for about a day Then randomly it stopped working and i checked the wire connection to the plug and they seem fine. i also tried a new outlet plug to see if that was the problem (it wasnt) what could be the problem it is the only outlet in the room that doesnt work. Thanks!!

It sounds like you know almost nothing about electricity, and will burn your house down. While it may vary, you would usually need to connect the red wire, since that usually indicates a live wire. You should take a class or two on home maintenance and electricity (or a physics class) in order to understand the basics.

Q:I live in Ontario. I would like to buy the electrical wires with 60%-80% copper inside and export them to China. The metal recycling company wanted me to make the offer first. This is my first time running this business. So, How much should I offer? Range or the prices?I know that I can get them at a lower price from the factories (sources). However, I don't have truck to toll them. Also, can I pay the recycling company more to ship the containers to China for me? Do they do that?

In addition to Bill G's answer, you need to check with your government, as you MIGHT need an export license.

Q:I'm 18 now, but when I was 15 (sophomore in HS), I did a lot of electrical wiring upgrades around my house. I changed the fuse box to a circuit breaker panel when I was 16. That same year, I did some wiring at my girlfriend's house (her dad let me). I installed a ceiling fan in her room and one in her parents' room.Do teen boys typically know how to do this? Or am I the exception?

No it is illegal in most countries for someone other than a licensed electrician to do such things.

Q:I purchased a lamp at Home Depot without thinking it through all the way. I want to hang it above my sink but there is no electrical wiring in the wall there to hook it up. Is there a way to convert it from one that is electrically wired into the wall to having a long wire and plug it into an electrical outlet?

Sure, you could buy an extension cord, cut the end off and wire it to the socket. But you wouldn't have an on/off switch. You could buy a light socket which has a switch and replace the one on the fixture. Without seeing it that is about all I can tell you. Good luck.
