MsQ Posted March 23 Report Share Posted March 23 I've been getting quotes fttt5rom electricians to run 220 wire to my hot tub in the backyard. One of them suggested I can use the 240 volt wiring from the laundry room since I don't need it for my dryer. The problem is this wire is only 30 amps and the spa suggests 50 to 60 amps. This guy insists that it won't be a problem and even with seven people running all the Jets full power that it won't trip the breaker. He said if anything trips a breaker it would be from heating it. Does this guy know what he's talking about? Quote Link to comment Share on other sites More sharing options...
cranbiz Posted March 23 Report Share Posted March 23 It depends on the wire gauge going to the dryer plug and how far from that location your hot tub is going to be. IF the dryer outlet is #6 wire it is good for 55A at 60' so the total length from the breaker panel to the hot tub thru the dryer outlet cannot be more than 60'. #4 wire is good for 60A at 75'. The dryer outlet has a 30A breaker, it may have heavier wire that will support higher current draw than 30A. That's what you need to find out. I wouldn't trust the guy that said this is safe without knowing what the wire to the dryer outlet is. Somehow, I don't think it's #4 and also doubt it's #6. It's probably more like #8 and that is to light to properly power the tub. I ran #6 to mine at 50', I helped a friend run #6 to his at 60'. 1 Quote Link to comment Share on other sites More sharing options...
Jay G Posted March 29 Report Share Posted March 29 Honestly, I'd find a new electrician. Quote Link to comment Share on other sites More sharing options...
