Hello. Welcome to Just Answer.
There is a tandem type breaker that fits the CH series of Cutler Hammer panels.
As a side note, that is Cutler Hammer's older, original model. They have since released the BR series.
The breaker frame on the BR series is basically identical to the Siemens residential breaker, as well as GE, and Square D Homeline.
Anyway, here's a link to the breaker I believe you need, at Home Depot...http://www.homedepot.com/webapp/wcs/stores/servlet/Search?storeId=10051&langId=-1&catalogId=10053&keyword=cutler+hammer%20CH%20breaker&Ns=None&Ntpr=1&Ntpc=1&selectedCatgry=SearchAll
It would be the narrower style, shown in the first two photos from the left.
The CHNT would be for panels built before 1968.
I can post another Home Depot product page, which would allow you to compare the 2 part numbers. As for appearance, they look identical.
Would you like to see the other product page?
I'm not sure I would trust Home Depot's images completely, as it appears they used the same photo for both part numbers.
The CHNT does say "non current limiting", but it also states that it protects the wire from shorting and overheating by tripping to the off position. At any rate, it does appear they have both. My suggestion would be to take a single pole breaker from the panel with you to the store, and compare all the fine details, so you get the right one.
I don't think they would give you any trouble if you needed to make an exchange, if by chance you did somehow end up with the wrong one.
Yes, that's correct.
They are both rated at 20 amps, so for Home Depot to say it is "non current limiting" is a bit obscure. But the non current limiting takes longer to trip.
However, the time difference is minimal.
It's so fast, it wouldn't be noticeable.
Here's a forum chat that explains it well...http://www.sawmillcreek.org/showthread.php?65828-NON-LIM-Breakers
No, as long as your panel accepts it without any modifications.
Sounds good. Is there anything else I can do for you?
You can mix them if you want, there's no Code that says you can't. But personally, I don't like to mix lighting and outlets when installing new circuits. Would you like to know why?
Imagine going into a carpeted room to run a vacuum. You turn on the light, plug in the vacuum, and due to a problem with it, it trips the breaker. Depending on ambient lighting, you could now be in a completely dark room trying to find your way out without tripping over something.
Thanks so much for the opportunity to help.
