48AMP kiln on 60 AMP breaker *must be* direct wired in Canada?
I never found the answer to the specific question &quot;what part of the code&quot;, but I did speak with some electricians who indicated that if the kiln were permanently installed it would be considered a 'continuous load', similar to a 'heating appliance' like a stove or a furnace.
However, my kiln is on wheels which I use to roll it into the corner when not in use. As such, the electrician said it is a temporary appliance that should not be direct wired. As such he installed a 60 amp breaker and the correct receptacle for the plug on the kiln (6-50), and a switch inline between the two. He indicated it is safer to turn the plug off first and then remove the plug instead of pulling the plug with 240V at 50 amps available.
