Service upgrade or sub panel?
Hi there everyone,
My question is about how to add a hot tub to my panel that is maxed out on breaker space. I have a 200 amp main GE panel(quad breaker) and I am currently pulling 100 amps on one leg right now. I have a tankless water heater, 3 A/C spaces and another 2 water heaters. Square footage is 2800 if you need that. I will be posting pics here shortly. Thank you. Let me know what other info you need? Do I need to upgrade service or can I just add a sub panel?

A demand load calculation will tell you if there is enough capacity for the added load from the hot tub.

Thanks for the response pcboss,
How do I perform the demand load calculation?
The hot tub label says it pulls 40 amps and it came with a 50 amp breaker installed inside unit.

Just do a search on the web. Here is one example: http://www.docstoc.com/docs/97696973...lt-Enterprises
