The dryer is using our "standard" such cord. Think of a heavy three-wire 'zip cord.' Dryers are usually on a 220v, 30 A circuit. Ranges are usually 40 to 60 amps in size. No, the dryer receptacle was not attached to the wall. FWIW, it was tied into the range circuit, using a very nice 'flying splice', removing piece of conduit, and other niceties.
Hello Paul, the person who did this was infact using the range receptacle for a junction point, and as you guessed, (but not quite as bad as feeding 15 amp recepts) the newer #10 NM's were feeding two 30 amp receptacles from this 60 amp branch circuit.
Thanks John, it certainly seems as though range receptacles are a target for the creative individual.
This receptacle was one of many interesting (kind way of putting it) finds in this older house. I have miss placed the disc, but when I find it I'll post them in another thread.
