60 amp breaker on a 100 amp service

(1/2) > >>

Alias A:
I have a older home with a 100 amp service and want to add a 60 amp sub panel for a 60 amp rated spa. My hvac unit with air conditioner uses about 30 amps. I will be using about 90 amps total if they are both on at the same time. Also lighting etc... Will a 100 amp service be enough?  Also how much amps does a 60 amp spa actually draw?

cranbiz:
It's pushing it as when the AC is on and your normal house load, you certainly could exceed the service limits. A 60A rated spa will use probably 55A if running all the pumps, blowers and heater.

I know that you don't want to hear this but you probably should upgrade your main panel.

Water Boy:
Would not be up to code, and I doubt any electrician would install that. Like the other guy said, might just have to bit the bullet and upgrade panel.

Spatech_tuo:
The question is fine (if you're not sure, ask) and NOT AT ALL uncommon but the answer is a clear "sorry but that won't fly". The only time that setup happens is when someone has a reckless brother-in-law who considers himself a DIY electrician but barely understands what he is doing and/or figures "what the heck, its not my house".

Alias A:
Any idea what upgrading the service panel would cost??
