Customer Questions & Answers

Wire Size

I have an existing cable in the wall that is 10 AWG x 3 conductor, and the current breaker is 30AMP. I would like to swap out the breaker for this one because we have a 40AMP oven coming. Is it absolutely necessary to bump the cable up to an 8 AWG x 3 conductor?
Asked by: Mike
Hello Mike, I’m Chris from the Home Depot’s how-to Community. Thank you for your question. Yes! Not maybe, not sometimes, but absolutely you must use 8 gauge and not 10 with a 40 amp breaker. I hope this helps, Chris. .

What circuit breakers are compapable with GTE Sylvania

Asked by: plumber
Dear Valued Home Depot Customer, We have reached out to the MFG for more information and their response is below. "We don’t recommend crossing (mixing) different manufacturers breakers in load centers even if they fit. They will void any warranty along with being a potential fire hazard"..

Asked by: Anonymous
Hi Kev, Thank you for your question. The MFG, did confirm that They are interchangeable as long as the load center accepts ½” breakers. Hope this helps.

is a GE Q-Line 40 amp 2 in. Double-Pole Circuit Breaker, interchangeable with a Zinsco UBIZ-240 40 amp 2 Pole

Asked by: Anonymous
This is Tom, also known as HD116 from the How-To Community, Unfortunately, there are no known compatible breakers to a Zinsco breaker. They are quite unique, and from my understanding the company is now out of business. My personal electrician said they can only be found through ebay, craigs list, etc. The other option would be to switch out the panel to a GE, Square D, or other common brand. Hope this helps...

Customer Reviews

Q-Line 40 Amp 2 in. Double Pole Circuit Breaker is rated 4.0 out of 5 by 5.

I have purchased several of these (one as recent as today -- Home Depot Item Number (on my receipt) is 783164012934) and have seen a marked decline in quality. The breaker form, fit, function is ok, but the LETTERING is washed out making it difficult to see the amperage rating, ON/OFF. This is not a one-off problem --- I've seen this with most, if not all the GE breakers at Home Depot. All one need do is compare it to compare it to other breakers (Siemens, Square D, etc) and you'll immediately see the problem. The other breakers are well stamped and the lettering clean and clear. I'm not sure, but the stamping / lettering problem on these breakers may put GE breakers in violation of the Nat' Electrical Code (it's frankly that bad).

Rated 5 out of 5 by from Item was as expected The circuit breaker was as-expected. It fit the panel well and operates as it should.

Rated 5 out of 5 by from Well duh for the other post! Because most home owners do not know what they are doing let me clue you in. Code requires that only breaker specified can be used in any given main box. Meaning that if you have a GE main then you use GE breakers. If you have a Zinsco main box then you use zinsco breakers, ect... Code is written that way so people don't force a breaker that is close to what is needed in place. Only a silly person would take such risk of fire by doing so because electricity does jump and cause fires.

Rated 4 out of 5 by from I would recommed using this breaker only in GE panels. GE is a good quality product sold at Home Depot at a very competitive price.
