What’s your house wiring? An old 3 wire 50 amp circuit that you’re reusing? Or a brand new 4 wire 50 amp circuit?

Check the circuit breaker or fuse to verify that the circuit is 50 amp. Look at the outlet on the wall. Depending on whether the outlet is 3-wire or 4-wire, purchase a cord whose plug looks EXACTLY like one of these.

I’ll go look! I do know we got new electric/wiring in the kitchen for it!
