ECN Forum Forums General Topics of the Trade General Discussion Area Thomas and Betts Panels

Hi

First post : >

I have a Thomas/Betts panel (125 a max) which already has 4 circuit breakers(can't make out the name of breakers, worn out)

I need 2 extra lines for 2 air conditions( have 4 free slots) electrician said if i pick up supplies it will save me money.

I bought the BX cable(require here in NYC) but not sure what type circuit breakers i need.

I know i need single pole 20 amps each but i don't know what brand is compatible with Thomas and Betts panels.


Panel Description: 120/240VAC NEMA 1. 125AMP MN LUGS ON

Catalog number: TBL12 (8-16)CG

I went to Thomas and Betts site but i can't find ANYTHING for circuit breakers (weird)

Any help ?

Thanks

hmm; T&B markets breakers listed for 8 panel types ( 7 including itself)
UL file # E162469
Westinghouse
Bryant
Challenger
Sylvania
Murray
Siemens
GE
T&B

One would think the T&B panels would accept the same, but I have no listing info available on this.

Sparky,

First off thanks for your quick reply : >

So any circuit breaker is ok from the list in your post?

Is it ok to mix different breakers from different companies?... being that i can't make out the name of old breakers.

Thanks so much

I went to T AND B ,entered the file number u posted and nothing found for that number.

Do u have a link?

Thanks

Yes, you can mix manufacturers for the most part (Murray objects to this practice).

What you can't mix is the Type.

You need to know whose shape is used for the breakers. Removing the panel cover and reading the side of the breaker is a way to find out. The ultimate way - with no other markings - is to remove a breaker and take it to the store with you. But you have to know what you are looking for. There are shape differences that don't matter at all. And there are subtle differences such as between BR and BRD that make all the difference.

There are already 2- 15 amps and 2 -20 amps all single pole.

When u say "What you can't mix is the Type" what do u mean by type as oppose to manufacturers?

When u say
" And there are subtle differences such as between BR and BRD that make all the difference." What is BR and BRD?


I measured the existing breakers and they are one inch so i know i need this size.

Thanks

Blue,

Any Electrical Supply House should be able to help you.

Blue;
Al i have is a catalog.
Bill is right.
Go to a local supply house, not a hardware store, there's a big diff.
out of curiousity
please post us back

>what do u mean by type as oppose to manufacturers?

Type is the design or style of the breakers, specifically, how it attaches to the bus.

> What is BR and BRD
Two of the many Types of breakers.

>I measured the existing breakers and they are one inch so i know i need this size.
Most are that size. half-inch and one-inch are very common.

But that doesn't tell me much of anything about the Type except that they are not half-space breakers.

Without seeing your breaker, I cannot tell its Type.

OK, i went and got a magnifying glass and look real close at panel box...this is what i found

Chall ( couldn't read the rest ,worn out) assuming it's a Challenger.

TYP c115 120/240 v (aslo something here but worn out)

cu/al swd
hacr ( also something here but worn out)

Listed circuit ( also worn out here)

1 pole J-977

----------------------------------------
Ch(worn out)

type c120

cu/a1 swd

1 pole j-952


A bunch of numbers on bottom of the 4 breakers but i can't make them out.


If this is enough info can u direct me to a link where they are?( want to look at the pics)

I hope this helps you help me : >

Thanks so much to everyone
