If you install a single pole breaker you will only be able to supply 120 volt loads from the panel. A double pole breaker will allow you to run either 120 or 240 volt loads from the panel.

If you installed a single pole breaker only every other buss finger would be hot in your panel.

Double pole, because that supplies 240V. Also because no one manufactures a single pole 100A breaker.

New Kiln - Need Advice

S

sarafina on Mar 08, 2009

I bought a used kiln yesterday that is 220V @ 20 amps and has a NEMA 6-30 plug on it. I have a gas dryer and do not use my 220V plug and want to use it for my kiln, but the receptacle is a NEMA 10-30. The man who sold me the kiln gave me the 6-30 receptacle he was using. I would like to change out the 10-30 receptacle to the 6-30 one he gave me. Is this safe to do? How do I wire the 6-30 receptacle? Thanks, SarahRead More

Swapping out main breaker in 200A box for 60A main breaker

tekkitan on Mar 05, 2009

I am still in the process of upgrading my electricity, waiting till it gets warmer out. Anyways, I have a brand new GE 200A panel with 200A main sitting in my basement. I want to do the panel upgrade (from fuse box) first before getting the service upgraded (currently 60A). Can I swap out the 200A main for a 60A main so I can do this conversion, then when I am ready to upgrade my service, swap the 200A main back into the panel? Thanks.Read More
