I have a 220 v, 36 amp kiln. I was hoping to plug it into my dryer outlet
but my outlet is for 30 amps and so is the associated breaker.
Someone told me the 30 amp dryer plyg can handle it. Wouldn't that trip the
breaker?
Any suggestions?

Changing the plug on your kiln may void the warranty and the
UL listing. The kiln would also trip the 30 amp breaker.
Your peace of mind and safety are worth more than the cost
of a new circuit.

Probably. You want a little extra capacity,
definitely not less, or you won't be able
to run it at full power. The breaker could
be upgraded to 40 amps, and the 30A outlet
receptacle _may_ be fine (better to hardwire
if in doubt), but you need to check on the
size of the wiring in between. If it's not
up to it, bad things can happen!

No, no, no. Bad Idea.
Since standard sized breakers give you the choice of 30 amps or 50 amps, you
need to find an opening in your service panel for a 50 amp double pole
(220/240 volt) breaker. And while #8 wiring will handle 40 amperes, because
you have a 50 amp breaker, you need to provide a branch circuit that will
handle 50 amps and that requires #6 wiring.
It's one thing to skimp on quality, but entirely a different thing to skimp
on safety. If you can install the wiring yourself, you're looking at less
than 100 bucks. If a licensed electrician installs it for you, you are
looking at a few hundred bucks. Isn't the safety of your home worth a few
hundred bucks?

Lisa,
The dryer plug would probably handle it, but the breaker would not.
Three things ---
1) To be safe, get another plug. Preferabley one rated to 50 amps. That
way you will have a safety margin,. A plug not rated sufficiently can
get hot.
2) You must up grade the breaker to match the amperage of you kiln. The
new breaker amperage must be rated at least 10% above the rated amperage
of the kiln.
3) The wiring from the breaker to the plug for the kiln must be of
sufficient diameter to carry the amp load. Otherwise the wires will get
hot before the breaker trips and you could have a fire. So have an
electrician check the wiring as well.
Good luck,
John Rodgers

Thank you all for your advice and I agree completely. We are getting an
electrician in to do the wiring.
A friend of mine said it would be no problem as that is what he did but I
didn't think it sounded right as he seems to cut corners all over the place.
Thanks again. Safety first!
