Quick Answer
To wire a generator with a bonded neutral correctly, connect the neutral wire to the ground rod or a grounding system at the same point as the ground wire, then run the neutral wire to the load center or panel. Ensure the neutral wire is kept away from the hot wires to prevent electrical shock. Use a bonding jumper to connect the neutral wire to the grounding system.
Choosing the Right Equipment
When wiring a generator with a bonded neutral, it’s essential to choose the right equipment. The generator should be a single-phase unit with a bonded neutral, typically marked as “bonded” or “grounded” on the nameplate. The bonding jumper, which connects the neutral wire to the grounding system, should be rated for the same ampacity as the generator’s neutral wire. A 4/0 AWG bonding jumper is a good choice for most generator applications.
Wiring the Generator
To wire the generator correctly, start by connecting the neutral wire to the ground rod or a grounding system at the same point as the ground wire. This is typically done using a grounding clamp or a grounding lug. Then, run the neutral wire to the load center or panel, keeping it away from the hot wires to prevent electrical shock. Use a wire nut or a compression connector to secure the neutral wire to the grounding system.
Grounding and Bonding Requirements
The National Electric Code (NEC) requires that the neutral wire be bonded to the grounding system at the same point as the ground wire. This ensures that the neutral wire is at the same electrical potential as the grounding system, creating a safe path to ground for fault currents. When wiring a generator with a bonded neutral, it’s essential to follow the NEC requirements for grounding and bonding to ensure a safe and compliant electrical system.
