My wife is ceramics teacher and we are making our garage into a studio for her. We already have local approvals etc.
There is no electric service there, yet. We have the POCO onboard with the kilns, we are getting a dedicated pole mount transformer, for free on a new pole for free, when did they get so nice?
We are putting a new service (main not yet determined) in we will only need a maximum of 20 circuits including the kilns on two pole breakers with ties.
My question is what do you use to figure the load calc. They are 1ph 120/240 kilns, one at 60A one at 40A.
Does 210.19(A), 215.3, and 230.42 apply to kilns like a dryer? Or does 424.3(B) for electric heat?
Also, does anyone have an opinion on whether you would direct wire or use plug disconnects? My wife has seen both types fail at other places with kilns. Now I don't know if they were installed properly, so I'm not sure why they failed.
Obviously the plugs are more convenient, but that seems to be a weak link that would wear out, any opinions?
