100 amp panel - DIY Chatroom

67corvette · 11-08-2009, 05:01 AM

I have a 100 amp 24 circuit panel which is full. It has 2 twin breakers already. I need to add 4 circuits for a/c. Can I add a sub-panel? I would remove 2 circuits from the main panel put in a 50 amp and run the sub-panel off of that. I don't have any heavy appliances mostly gas. The load should be fine.

What size amps is the new ac's 4 of them ? window units? You can run a new sub panel has to be 4 wire with a ground bar.

Ground rods are not required if the sub is in a structure attached to the same structure as the Main panel
