must be taken from the 240V-4P receptacle.

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.
