Size of wire for my new hot tub question

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.

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.
