Well you can go the usual route and tell them that the trade calls Federal Pacific, FPE-No Blows, and that the really niffty thing about these breakers is that you can weld with them and not have to ever worry about them ever tripping.
Even our inspectors are totally against these panels, they wont even accept new ones, and I suppose, to the customer it looks like your trying to sell them something they dont need.
Good luck with this one
