I know i can google it probably but i figure i ask first. If anyone is in the process of adding a breaker to their breaker box would you be so kind as to do a real simplified write up ? All i intend on doing is adding a breaker for a few lights and i want to add another for a dedicated outlet for my craps men compressor.

Of course you first turn off the main breaker !

I'm not a pro, but twice in the same breaker panel I somehow managed to NOT get the screw under the clamp !

For me, it was easier to remove the new breaker, install the wire under the clamp and then install the breaker.

After the breaker was installed, I did give the clamp screw an extra turn !

Last step before turning on the main breaker, give that wire you just installed a good tug !

And I prefer to not throw a main, or any other breaker on under load. So I turn off the main, turn off all the breakers past the main.............. turn on the main, then turn on all the breakers individually.

Interesting - I usually don't turn off the main. I install the breaker, then route the hot wire, trim, strip, insert in the breaker and tighten the screw. If it's a big wire, then I might pull the breaker back out, clamp in the wire and re-install the breaker. I use gloves and insulated tools. you can guide a wire pretty fiirmly with a nice set of needle nose. Nothing wrong with killing all the power but check the flash light batteries first LOL. I just hate killing every thing in the house. Too many dang clocks to reset.

I think i got this correct , so for example if im installing a 20 amp breaker i run the wire in to the breaker obviously and the black goes to the breaker , the white goes to the neutral buss bar and the bare copper goes to the ground. On the receptical side ( outlet ) the white and black go on to the 2 screws on the side of the outlet while the bare ground goes to the screw on the top

I get a monthly electrical trade magazine that has a regular feature called 'Forensic Casebook.' It's a column where they discuss various electrical accidents. The latest copy just came today, and the subject matter was about a guy who tried to change a circuit breaker hot. He dropped his screwdriver which created a ground-to-phase fault, and as a result of the ensuing arc blast he spent 6 months in the hospital recovering from burns.

The point is, I know people do it all the time but I'd never recommend working hot, even if they know what they're doing.

If you are that uncomfortable and unfamiliar with doing it, get a professional to do it for you

Adding or changing a breaker takes a little knowledge of electricity and skill, not a write up.

For the record, I'm sure you intended to say: the black wire attaches to the gold screw, the white wire goes to the silver screw and the ground goes to the green or ground screw.

scary **** , id never work on anything hot. Even with everything off i get a little scared touching anything until i finally confirm that it is indeed off.

Id say im pretty comfortable now that i wired up some lights and some other **** so im becoming a little more familiar with everything. Just wondering from what i wrote does that sound remotely correct ?

Specifically, the White wire goes on the Silver screw, which is the wider of the blades/slots, and the Black goes on the Brass screw, which is the narrower of the blades/slots on the front.

Problem is, if you are interested in doing this anywhere close to the code, there are a lot of things to know. Things such as how far from the box the first romex staple is supposed to be, the fact that sheet metal screws are not allowed for ground screws in a box, and that they must be green, and must have at least two threads of grip in the box, or that the face of the box cannot be recessed inside of the finished wall surface more than (If I recall correctly) .040", or that if using screw terminal type receptacles (as opposed to back wire type) that the screw must be wrapped at least 2/3 of the way around the screw. The details just go on and on, some being common sense, some pretty weird.

There are good books on the subject of handyman/DIY wiring and these should help you alot with code compliance.

Thanks for clearing that up. Not worried about so much to code but more safety wise

I added my last circuits without turning off the main. I did use electrically-isolated screwdrivers though. If the new breaker is off, one option is to hook the wire to the breaker, then install the breaker into the panel, then turn the breaker on...

I've seen electricians work "hot", but I'm more cautious....I not only turn off the main, but also meter out everything I might touch, even accidentally - just to make sure it's dead.

You only have to touch a live 480V 3ph once to learn to be cautious - assuming you live. I have a "dead spot" in one of my fingers where I was pointing something out in a live box and got jostled.....it still hurts sometimes...

And 110v house current can kill you too.....

The NFPA 70E requires that the main be turned off, before removing the cover shield and working behind it. It actually can even require that the source to the panel also has to be opened, depending on the type of panel.

Granted, you don't have to follow that at home, but it is a good precaution. Things happen and things break, that are outside of our control and awareness.
