(2) CONNECTING TO DOMESTIC CIRCUITS (HOUSE WIRING)
All Makita generators are a neutral grounded type.
If a generator is to be connected to residential or commercial power
lines, such as a stand-by power source during power outage, all connec-
tions must be made by a licensed electrician.
Failure in connection may result in death, personal injury, damage to
generator, damage to appliances, damage to the building's wiring or fire.
WARNING
(a) When connecting a Makita generator to a house wiring, generator output power
must be taken from the 240V-4P receptacle.
(b) Install a transfer switch.
A transfer switch must be installed to transfer the load from the commercial power
source to the generator. This switch is necessary to prevent accidents caused
by the recovery from power outage. Use a transfer switch of the correct capacity.
Install transfer switch between the meter and the fuse or AC breaker box.
If the neutral wire of house wiring is grounded, be sure to ground the ground
terminal of the generator. Otherwise an electric shock may occur to the operator.
