5-2-8 CONNECTING TO DOMESTIC CIRCUITS (HOUSE WIRING)
WARNING :
All Robin generators are a neutral ungrounded 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 connections must be made by a licensed electrician.
Failure in connection may result in death, personal injury, damage to generator, damage to appli-
ances, damage to the building's wiring or fire.
(a) When contnecting a Robin 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.
Caution : 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.
