220v to 110v

You also have the second 120v circuit by duplicating that with another 20 amp breaker at the panel and sharing the neutral, but the guys here will probably scream.

Anyone else want to comment on whether or not this is a good way to accomplish my goal?

If the instructions say 15 amp them a 15 amp breaker is the largest that you should use. Everything else will be okay

I service a lot of apartments where the panel is in the bathroom behind the door when it is swung open, and also closets as long as there is 3' open space in front of it.

So use 15 amp breakers on that big wire rework. You would have to clip some of the leads to get it to fit the breaker.

Thanks for all the help everyone!!!!

DO NOT CLIP ANY LEADS!
Pigtail the correct size wire to the current wires.
Do this on both ends to make sure the wires fit the brakers and the receptacles.
Use a double pole 15 amp breaker or use breaker ties.

If its solid wire he would likely have to do that, or it might fit into certain breakers as-is.

Seems like he should have 2 seperate breakers as he is creating 2 seperate 120v circuits.

A shared neutral circuit should have both legs turned off at the same time, thus the double breaker or the ties between them. Then, if either leg has an overload, it shuts both off. Possibly an annoyance. The way around that is a subpanel.

I suppose that eliminates any chance of some stray juice in the neutral, but a very small chance it is. Still less annoyance than adding a subpanel. Use the double breaker.

Ballvalve, You should not be giving any information on any electrical install as it is apparent that you have no electrical experience as most everything you have stated is incorrect or just down right dangerous.
OP If that existing cable is a 4 wire you could split it up and install that proper over current protection in the existing panel. No real need to install a new panel anywhere if all you need is 2 circuits.

Sounds like you didnt read the whole thread and other electricians opinions. May as well insult them by name also to be really obtuse.

your last paragraph is what I said. What is "OP"?

Maybe you missed page one.

**arfeller** · 11-27-2010, 11:50 PM

"OP" usually refers to the "Original Poster" of the thread.

**ballvalve** · 11-28-2010, 11:10 AM

sbrn, still waiting on your apology! Thanks in advance.

I can’t help how many illegal installations you have seen or how much moisture is on the outside panel I am sure that you understand that it is still illegal to install a panel in a closet and also sure that if you are truly an electrician you know the difference between the panels approved for outside installations and an inside panel.

I truly hope that you didn’t say this and use the term “electrician” to describe yourself.

Just what are you talking about here, “stray juice”?

I agree with this post in its entirety

Okay here it is…”I’m sorry that you think you are an electrician”

Rock pretty much said it all. My only apology will be that I didn't get back to the forum faster and Rock beat me to it.
Ballvalve, I will say it again, by reading your post you have proven to me(and apparently some others) that you are not an electrician. You may be a great plumber(going by your name) but that doesn't make you a good electrician. It's OK, I just don't want you giving advice that has no sound reasoning, code basis or workmanship issues.
