wa2ise, "F"&S? The P&S bunch have been around quite awhile as well. Does anybody here know what the code said in the past about these non-NEMA (10A-250V) receptacles as pictured?
I'd have a big bunch of non-NEMA twistlock recps. and caps (10A-600V) if I hadn't smashed them all years ago so they wouldn't be used again.
It'd be neat if somebody could show a 10A C/B that would mate up with them....fuses, huh??...S
