What are some of the quotes you have received to get a NEMA 14-50 installed in your garage? We have the breaker box on the same wall where we would need the outlet installed, the wire to run would be under 10 ft and the electrician would be installing a new circuit breaker for the NEMA 1450. He quoted us 550 for labor and parts. Is that in the ballpark of what you paid? We are in the DFW area.
