Quick Answer
You can use generators in wet locations without ground fault protection, but you must take extra precautions to ensure safe operation. This includes bonding the neutral to the frame and using a GFCI-protected outlet. Regular maintenance is also crucial.
Generator Grounding Bonding
To safely operate a generator in a wet location, bonding the neutral to the frame is essential. This is a critical step in preventing electrical shock. The National Electric Code (NEC) requires a bond of 12.7 mm² (2 AWG) copper wire between the neutral and frame. Use a lug or clamp to secure the bond wire to the generator’s neutral and frame.
GFCI Protection
Install a Ground Fault Circuit Interrupter (GFCI) outlet to protect against ground faults. GFCIs are designed to detect ground faults in as little as 1/40 of a second, significantly faster than traditional circuit breakers. When shopping for a GFCI outlet, choose one with a rating of 20 amps or higher to accommodate the generator’s power requirements.
Regular Maintenance
Regular maintenance is crucial to ensure safe operation of the generator in a wet location. Check the generator’s neutral and frame for any signs of corrosion or damage. Clean or replace any corroded parts, and inspect the bonding wire for any signs of damage or wear. Additionally, ensure the generator’s spark arrestor is clean and free of debris to prevent electrical shock.
