Not a lot to say about this one... it was convenient to just order since most of the big hardware stores don't carry the single pole 40amp breakers. It arrived quickly and is working great. To me, ordering parts like this is a no brainer. I would recommend square D breakers to anyone as they are about as cheap as the others but seem to hold up better.

Great value, we are full time RV'ers and this has been a inexpensive fix, instead of going to a RV Dealership which would have been outrageous! UPDATE-- This was easy to do as well, after reviewing my comment I believe I should add this can be done by most people, it is not hard, follow some Utube videos and just remember you are dealing with electricity so make sure you take all safety precautions. And remember to get the correct part for an RV not a house.

They work as expected. Not much else to say. The red trip flag is a nice feature and also being able to get duals in the same footprint is great flexibility on a full panel.

The Breaker I received was a dual 20amp style. I specifically ordered this single 40amp as the local hardware stores don't carry them redialy.Looking at other reviews it seems I'm not the one with this same issue..
