Re: [RE-wrenches] Breaker Space Knockouts

[Allan Sindelar]

Several years ago we added 3,200 watts to an existing 24V system with an APT 4B, which has only 5 CD-style DC breaker spaces. We had to add four more OBDC panel-mount breakers. We installed them in the cover of the SW4024's DC conduit box. Same method; drill, jigsaw with tape to protect against scratches, and files. This one had to look clean, as it was a permitted/inspected upgrade and it had to look like it was done that way at the factory. Probably took an hour to get it right and fool the AHJ....

I drilled holes first to eat up most of the spot I wanted to remove and then used a jig saw. I filed the area after I was done. It looks good. I put a very thin bead of grey caulk around the edge to hide the spot that I "colored outside the line".

I would tape over as well to avoid scratches. I know they make punches, but they're stupid expensive, and easy to break the corners off.
