    Household wiring - simplified diagram

    This diagram explains the basics of how 220 and 120 are derived within the electrical panel at your house. The wiring at your home - especially if it is older, may not look like this so if there is any doubt about what you are doing, contact a qualified electrician.

    This is posted mainly to clarify the 220 circuit. I have seen many questions about how to hook up a welder, etc. and this diagram should help those DIYers that may need a hand figuring things out.

    Re: Household wiring - simplified diagram

    Wow. I forgot about this thread. I have more helpful wiring stuff somewhere. I will dig it up and post it. Stuff like 3-way and 4-way switch wiring, motor controls, etc.

    Welcome to the board, PanelDeland!

    3-way and 4-way diagrams would be a valuable asset! What kind of motor control stuff do you have, Scott?

    I thought it was on my PC at work, but no. I guess the stuff is on my PC at the shop - I will look for it tonight......

    Motor control stuff is tumbler switch wiring I believe, but if you have anything specific, I am fairly well versed in motor control (no expert but I can float).

    I do have a doc telling you how to identify the nine leads of a three phase motor - something few have to do often, but a real PITA if they ever become unidentified. I will post it, too.

    Here is a decent site for the basics. This site has diagrams for everything from the most simple to the more complex wiring situations regarding the use of switches including simple and complex three and four way switches.

    Re: Household wiring - simplified diagram

    I am a big pusher of DIY stuff, but I want to say this:

    PLEASE, use extreme caution when doing you own electrical. Mainly if you are unfamiliar with it. While most people look at an electrical job as correct so long as it works as expected, this is not always the case. The NEC was written and is maintained by Firemen. There is a reason there are codes.

    Please be sure any electrical work you do is up to code to be as safe as possible. Please do not cheat or cut corners when it comes to electrical. And most important, if you are unsure, ask someone or hire a professional.

    Now with that said, I am pretty good with the electrical so if anyone has any questions, feel free to ask.

    How to identify the nine leads of a three phase motor:

    You might want to print this out and keep in a safe place. This is difficult info to locate from my experience.
