Customer: double mini breaker The Electrical Doctor : Theres your problem. The double mini breaker is only designed to fit into one single pole breaker space. Because of this your not getting 220v. This is why your tanning bed is not working. You need to install a true full size 30amp double pole breaker in order for this to work. thank you we will go exchange the breaker to full size and see if that works will let you know in about an hour thanks again. No problem - I will be here.
