doing an inspection when I took the panel cover off I noticed a 75 amp 4 pole breaker. Is this a 150A breaker??
This was fed with a 3 AWG THW copper wire. Is this under sized for this box? My mind is saying yes.
I want to hear what you guys think?
Sorry for the sideways picture

Looks like 75 double pole.

The ratings on the handles do not get added. That is a 75.

Figured but wanted to double check. This is for a 4-Point inspection.

Indeed it is a 75A rated CB. The 3 CU THW is good for 100A @ 75° C so it is fine.
Where do those leads go from the breaker?
