Quality and Convenient
These are easy to install if you have a compatible plug on neutral box. Fits tight. Works perfect. No more searching the wall for the GFCI and looking for the breaker at the same time, it’s always all in once place in the box. Used 4 of these in my garage for 3 years so far and going strong. GFCI tester proves good functionality.

Great breakers, these came without retail packaging
The plug-on-neutral breakers are fantastic when you need AFCI or GFCI functions, which may be required for new applications or wet areas. It makes for very clean wiring without those coiled up neutral wires. There are many complaints about AFCI in general, but these breakers have been good for me in most all situations with quality wiring. If you have tripping issues, check the proper wiring. I found that other than my Dewalt table saw which trips anywhere 50% of the time at start, the AFCI/GFCI breakers have been trouble-free. These breakers came in plastic bags instead of the typical clam-shell plastic that you would get from the big-box stores. It may be that they are returns or bulk packaging that was sub-divided, but I had no issues with their operation or installation. As it was cheaper then the box stores, it is probably the case, but I cannot be sure.
