I am having a problem with the wiring for an electric motor attached to a compressor. I recently purchased this compressor. The paperwork with the compressor stated it was 2.2kw / 3hp, 220v/50hz, 230v/60hz, single phase. There were three ten gauge wires, so I ran a 30A circuit with ten gauge wires. After about fifteen minutes, I noticed smoke coming out of the circuit box that was plugged into the outlet. The two large capacitors had been on fire. I know that one of them is the motor start capacitor. They are 220-275VAC 200uF +/- 30% and 40uF +/-5% 450VAC 50Hz. I ordered replacement capacitors, but can someone help me understand why the first set caught fire? I initially thought it was reverse polarity, but that can't be the case with 240v. I tested each leg and they are each about 118v.
