(GLASS KILN'S) 240v 40 amp ?

Question

ok i need your help. ima first time kiln buyer and been doing a liitle research on how to choose a kiln. what im wondering is did anyone had to get any electrical work done using a kiln that requires 240v 40 amp? isn't that close to the same power used when you use a regular dryer? pleas help i dont what to burn my apt, complex down!!! lol

Answer 1

Yes.
120/120/ 240 split phase.
40 amps is a lot of current, or 20 amps per phase. I would suggest to brace yourself on the power bill.
You might not be able to use your dryer outlet. Is it a strait blade or twist lock plug on your Kiln? Your Dryer is a Strait blade Nema plug 30 amps, but you might have a twist lock plug, which you will have to have a electrician install it. I think 40 amps you would need 8 gauge copper wire, not 10 gauge used for Dyers. I think you have more then what you think.

Answer 2

No you should run onother curcuit that is dedicated for your kiln.The dryer curcuit would be tripping all the time and is not rated for about 30 amps Use a 50 amp breaker other wise it would trip at start up and use No 6/2 wire since you probable dont need any 120 volt on the kiln but check if there is any devices on the kiln that requires 120 v if it does use 6/3 Wire .And wire it to a 50 amp rated reciptacle.

Answer 3

A dryer generally runs a 30 amp breaker. My 5 ton central AC runs a 50 amp and the kitchen range runs a 70 amp breaker. My mother use to do china and ceramics and had two or three kilns. Just depends on what the main panel in your apt. is capable of. Make sure you use wiring rated for forty amps at the length you need to run it from the box to the kiln.

Answer 4

Yeah you will need a dedicated circuit. A standard power point is only rated to 12 amps and are fitted with 15 amp circuit breakers.
