This guy i know seems to think that he can take a 110 volt outlet with # 12 gauge copper wire & turn it into a 220 volt outlet just by changing the breaker & the outlet. Sure that is easy, problem is the # 12 gauge wire right.This is for a( DRYER ) is this not a bad call ? fire hazard maybe?wire needs to be 10 gauge for a 30 amp circuit right.
