Air compressor electrical

IS IT POSSIBLE to convert a 15 amp circuit with a single pole 30 amp circuit breaker on a 110 volt curcuit?   

Why don’t you change the compressor back to 220V and install a new 220V outlet just for the compressor. They have kits at Depot or Lowes for hot tubs running 220V, with the correct wire size and receptacle size. You can also get an electrician to come in and do the same thing, and it won’t cost all that much to have the peace of mind. It makes no difference to the compressor what voltage you use, so long as it has power. So just go back to basics and wire a dedicated outlet for your compressor to avoid any potential problems.
