SELECTED CIRCUIT COVERAGE
1. The generator powers only designated circuits that are grouped
together and wired into a separate priority distribution panel.
The transfer switch is installed between the main distribution
panel and the priority panel.
The amperage rating of the transfer switch must be equal to
or greater than the highest amperage rating of the utility and
generator breakers feeding the switch.
WHOLE-HOUSE CIRCUIT COVERAGE
1. The generator will be backing up all electrical loads within the
panel, so the amperage rating of the transfer switch must be
equal to or greater than the amperage rating of the normal
utility service.
A main service disconnect must be located before the transfer
switch. The transfer switch must be installed between the
utility service entrance and the building distribution panel.
2. The grounding that is normally in the main panel must be
accomplished in the service rated switch and must be
disconnected in the existing distribution panel.
ELECTRICAL CONNECTIONS
1. Connect the power leads from both the generator and the
utility to the appropriate lugs in the transfer switch. The lugs
are clearly marked in the switch.
N = Normal Utility Supply
E = Generator Connection Panel
T = Load Distribution Panel
2. Neutral wires from both the utility and the generator are
connected to the same neutral lug in the switch.
NOTE:
220VAC 2-Wire 50Hz applications will not have the Neutral
wires.
3. Connect the control wires from the generator to the designated
locations. Wires 23 and 194 connect to the terminal strip; N1,
N2, T1 and T2 connect directly to the fuse holders.
4. Complete the transfer switch wiring by connecting the
equipment ground wires from both the utility and the
generator to the ground lug.
