Customer Questions & Answers

Can I connect a manual generator transfer switch to these circuits?

I have a new home and almost all the light circuits as well as the bedroom and living room outlets have these breakers. I have the Reliance manual transfer switch for my emergency generator. Can I connect these circuits the same way as the normal circuits? Or do I have to change out the breakers for standard breakers on the circuits I want to put on the transfer switch?

on the 20 amp GE arc fault breaker are you allowed to put aluminum branch circuit to the breaker

Asked by: Gonzales
Yes, the GE AFCI breaker will accept aluminum branch circuit conductors if they are properly terminated by abrasion to remove corrosion and coated with anti-oxidant compound.

These add some piece of mind knowing that they could potentially prevent an electrical fire. I have been using the 15 Amp version for over a year on my lighting circuits with absolutely no issues. I finally decided to buy a 20 Amp one for an outlet circuit to test how they handle various loads and electrical noise. I have run my shop-vac, power drill, and circular saw as well as an assortment of other gadgets without a single problem. I now plan on converting my entire house over to these in time. They are pricey, but nothing compared to the cost and devastation resulting from a house fire

Rated 5 out of 5 by from touchy but worth it these are code for bedrooms & from what heard from an electrician they are now NEC code for all circuits they are ten times the price of normal ge breaker so ask before you buy them these are very easy to install good because i'm not a pro electrician but i do like to do things right i have got some very good advise from the master electricians at home depot these guys are pros ask them they will know what you need as for being touchy i had a lamp with a bad 3way bulb & it tripped the breaker just like it should have it took a couple of times to figure out the bulb so be safe

Rated 1 out of 5 by from trips every time we use the vacuum cleaner We had these installed in every bedroom due to code when we remodeled our house. Now my expensive vacuum cleaner trips the breaker every time its used on any of the arc fault circuits. Which is every room with carpet. So now every trim corner is damaged from rubbing from electrical chords and extension chords in order to clean the bedrooms. I will be replacing them all with regular breakers. Either the building code or the technology needs to change. Good idea, bad execution.
