I am installing a new compressor in my garage. I already have 240V installed to run a kiln. The kiln is only used maybe 10 times a year. My thought is to splice into the 240V line to the kiln to run the compressor which is also 240v. The kiln is wired with 10/3 off a dual 30A breaker. the compressor needs 12/2 and pulls 15A.
What is the best way to do this?
