My wife wants to purchase a kiln that will connect to the 30 amp dryer outlet. This is not an issue you simply don't run the dryer when the kiln is running. No biggie. My question is can I simply tie in to that outlet to put an additional one in the garage? The two units WILL NOT be run at the same time I am just curious as to whether or not there will be issues. I know rule 1 turn off the breaker and be sure to get the right gauge wire.
