FPE Panel Replacement is tricky and depends on the application.

For Homeowners: If you're looking for a replacement FPE Panel or FPE Panel cover for your home, you're virtually out of luck. I have not heard of anyone who offers such a replacement. If you reach this point, call an electrician and change your panel out. If I'm incorrect in saying that you're out of luck and you know a company who can supply these materials please correct me: fpesource (at) gmail.com

For Industry: Replacement Federal Pacific Panels and Panelboard from 208V to 15kV are scarce but still available. If you're looking for switchgear, please click here. Otherwise, i'd once again call the guys over at Satin and see what is available.
