I installed a Woodtek 3 hp DC which, according to the specs draws 19A. I had the electrician install a 20A circuit breaker on a dedicated 10ga drop. The problem is that when I try to run the DC the circuit trips. I replaced the 20A with a 30A and it works fine. I'm not sure this is the best solution. It was suggested that I replace the 30A with a 20A slow blow breaker. Is that the correct solution?
