Smile Possible new spa

I'm currently comtemplating the addition of a spa to my outdoor deck. I have not called an electrician yet for their opinion, but thought I could start here. Your assistance is appreciated.

The best location for the spa puts it about 50 ft from the main (about 100 ft of wire would be needed to go up and across or down and across to get to it). There is a sub-panel that is only 15 - 20 ft and a straight shot.

The sub-panel has a 60 AMP main and is wired with #4 wire. The current load is 4 - 20A/110, 6 - 15A/110, 1 - 30 AMP/220 that leads to another sub with a 20 AMP/220 and 15 AMP/110 breaker.

The spa would need a 50/220 GFCI w/disconnect wired with #6 wire.

Would this 60 AMP sub be able to handle the new 50 AMP load or will I need to come from the main? (a significant cost difference due to the length of copper wire, I'm sure)

Any info would be appreciated.

Now what do you think?

There is a reason the the tub needs a 50 amp circuit. Add that load to those other loads, even at minimal use and you are most certainly above 60 amps.

I knew that was the case. I was just looking for a cheaper solution. With the distance from the main and the difficulty with going through the attic or under the house--it will add about 500 to the cost for an electrician.

Oh well - thanks for the reply.

Remember that the circuit for the hot tub needs to be an insulated ground wire where the wiring is outside the house.
