Guys: I have two switch breakers that I need identified as to amp load. They are AMF Potter Blumfield units. One has the number 548-250-107 and the other has three numbers, 35-380132-9, 548-250-105, and a small number in the corner, 8231. I've googled the number and mfr, no joy. Any help would be appreciated, Dan from Reno
