I just got a quote for an install. $300. Just to supply and install a 50 amp 2 pole breaker and surface mount to a NEMA 14-50 outlet(I already bought this and the outlet box). Outlet will be about 6" from the panel. I thought this would be pretty simple and only take like 30 min. Does $300 seem like a lot, since I already bought the NEMA 14-50 and it is only 6" from the panel?
