Connect the vehicle’s breaker panel to the generator output. The HR-15 generator
is pre-wired to supply 120/240 VAC, the HR-12 generator is pre-wired to supply
115/230 VAC. The generator frame is bonded to ground. Route the generator
output conduit/wiring to the breaker panel, and carefully cut the conduit to length
without cutting the wire insulation. A conduit connector has been provided to
connect the conduit to the breaker panel. Connect the (4) four generator output
wires to the breaker panel as follows (see Figure 2 for electrical schematic and
wiring diagram):
HR-15 HR-12
Phase A: Black wire (120 VAC) Phase A: Black wire (115 VAC)
Phase B: Red wire (120 VAC) Phase B: Red wire (115 VAC)
Neutral: White wire Neutral: White wire
Ground: Green wire Ground: Green Wire
To completely utilize the generator’s output capabilities, the 115/120 VAC loads
must be equally divided between the generator’s two main windings. Before wiring
the vehicle, calculate the wattage of each 115/120 VAC load that will be connected
to the generator. Next, create two groups of loads based on total wattage (add the
individual wattage of each load together). Exchange loads between the two groups
until the total wattage of the two groups is as close as possible to being equal. Wire
the system with one group connected to Phase A (BLACK) and neutral, with the
other group connected to Phase B (RED) and neutral.
