1. Make sure the circuit breaker or fused disconnect switch is turned on.
2. If you have a circuit breaker, flip it back and forth to ensure it is fully on. Some circuit breakers, if they have tripped, may not be immediately apparent in a tripped position. By flipping it back and forth, you will reset the circuit breaker.
3. Check the voltage of your power supply at the receptacle using your multi-meter set to the next highest AC voltage above 240 (typically this will be 600 volts but may be 250)
4. Check fuses for voltage continuity. You can do this with your multi-meter.
5. Ensure fuses or circuit breakers are the proper amperage and type. See your wiring diagram for the required fuse type.

CAUTION: This test should only be done by an experienced person familiar with electricity.
