bob Senior Member Location Alabama Apr 19, 2008 #2 Yes. So you will need a 225 amp disc. Any problem with this?
D dave121 Member Location Central Wisconsin Apr 19, 2008 #3 No problem at all, just wanted to know that I was understanding the code properly so I can get the correct equipment in place. Thank you.
