Author Topic: Size of wire for my new hot tub question (Read 2521 times)

I am replacing my hot tub which was using a 50amp circuit breaker to my Artesian Santa Cruz Spa. The current wire is 6awg and is being run for approx 36 feet. Is this sufficient, and all I need to do is change out the circuit breaker??

Depends on your local codes but I think it's overkill in the NEC book.

Talk to an electrician and read up on NEC 2011. Double and triple check that it's 6 gage. Also you need to check the amp draw from the tub. You can put an 60A breaker on 6 gage copper romex wire. Although romex 6 gage is rated for 55 amp NEC allows to round up on the breaker size. If it's THHN wire than its rated for 65A. http://www.cerrowire.com/ampacity-charts
I'm sure the tub will draw less than 55 amp. As long as it does then it sounds like a breaker change to 60A will only be required while using the existing wire. Good luck and be safe boyeee.
