Generator AC Connection System

A single-phase, three-wire AC connection system is used in the home generator. The stator assembly consists of a pair of stationary windings with two leads brought out of each winding. The junction of leads 22 and 33 forms the neutral lead, as shown schematically and as a wiring diagram. A complete schematic and wiring diagram can be found later in this manual.

NOTICE Neutral is not bonded to ground at generator.

NOTICE Generator must be used with only an UL approved transfer switch that is compatible with the generator.

Grounding the Generator

The home generator must be installed as part of a system that includes a listed transfer switch, with neutral to ground bonding at the transfer switch in accordance with installation instructions. Unless mandated by local code, additional grounding to earth at the generator is not required. Any grounding at generator must use metal piercing lock washers (or equal), UL listed terminals installed per terminal supplier’s instructions, and comply with national electrical codes and local requirements.
