Installing A Pottery Kiln
Electrical question. Wifey wants her pottery kiln set up. I plan to do it in the garage, where I previously installed a 100A subpanel with a 60A main breaker, powered by a 60A breaker on my main panel and a ground cable to ground rods. The kiln will have the appropriate clearances to combustible surfaces. I'll put a smoke detector in the garage, and possibly a fan to vent fumes.
Here is a picture of the information plate. The plug is a NEMA 6-50 with two flat (hot) prongs and a round (ground) prong.
As I interpret this, I simply need to install a 40A 240V circuit breaker in my subpanel, and the appropriate wall receptacle, wired to the hot terminals of the breaker and the ground bar in the subpanel, via conduit. The receptacle will be dedicated to this use. I will try to find a GFCI breaker. We'll run the kiln at night. Am I missing anything?
The plate says
"2 way 240v AC
1 phase 21.7 amps
With . . . extension ring
32.5 amps 7800 watts"
I think we have the extension ring, but will check.
