Briggs & Stratton 30000 SERIES Generator AC Connection System, Grounding the Generator

Page 14

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 T2 and T3 forms the neutral lead, as shown schematically and as wiring diagram below. A complete schematic and wiring diagram can be found later in this manual.

NOTE: Neutral is not bonded to ground at generator.

Grounding the Generator

Ground the home generator per applicable codes, standards and regulations. There are two generator GND lug locations. The one inside the alternator junction box next to the circuit breaker is the primary lug and should meet most applications. The second generator GND lug is located on the frame below the generator circuit breaker cover, and should ONLY be used for a ground rod located at the generator, if required by local codes. See Controls for location.

Utility Circuit Connection

“240V Utility” leads must be routed in conduit. The

“240V Utility” leads deliver power to the generator’s circuit board and water heater. This power also charges the battery. When power on these leads is lost, the generator will start.

Using installer-supplied minimum 300V, 14 AWG copper wire, connect each ten-amp fuse terminal in the alternator junction box to the ten-amp fuse terminals in the automatic transfer switch.

Fault Detection System

The generator may have to run for long periods of time with no operator present. For that reason, the system is equipped with sensors that automatically shut down the generator in the event of potentially damaging conditions, such as low oil pressure, high water temperature, over speed, and other conditions. Refer to Fault Detection System in the Operator’s Manual for more detailed information.

The owner will use the remote LED indicator to observe the status of the home generator system. Consult with the owner for a convenient location. Locate the electrical box in an area visible by the home owner such as near a garage door opener or security control panel.

To install the remote LED indicator:

1.Push the LED through the mounting plate from the front until it snaps in place.

IMPORTANT: The LED is polarity sensitive.

2.Using provided 10 pole connector and installer-supplied minimum 18AWG wire, connect the remote LED to the generator control board +LED and GND connection. Use wire nuts to attach wire to LED leads.

3.Attach mounting plate to installer-supplied electrical box.
