CIRCUIT COVERAGE FOR WHOLE HOUSE AND SMALL COMMERCIAL

1. If the generator will be backing up all electrical loads within the panel, the amperage rating

of the transfer switch must be equal to or greater than the amperage rating of the normal

utility service. Unless a service rated transfer switch is used, 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. A service rated transfer switch is installed between the service and the main distribution

panel. The service rated switch becomes the main service so no service disconnect is

needed. The existing main distribution panel becomes a sub-panel.

3. 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. Refer to the National

Electrical Code (NEC) for complete information on grounding and bonding.

SPECIFIED ELECTRICAL CIRCUT COVERAGE

IMPORTANT

If the generator only powers designated breakers and circuits that are already grouped together

and wired into a separate specied distribution panel, the ATS must be installed between the main

electrical panel and specied distribution 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 feed-

ing the switch.

ELECTRICAL CONNECTIONS

Secure circuit connections:

• Users must connect the GND wire to the grounding lug and tighten.

• The GND wire should be the same gauge as than the load wire.

• Connect according to the following connector bar from left side to right side.

• Connect according to the following type due to different Models.

Use the insulated and certied wire/cable hose to connect the output hose and the AC output

wires/cable, and ATS control wires shall be separated by an insulation bushing (min 1.0mm)

Tighten all wires before operating generator set, or it will cause short circuit failure, do not

connect generator sets together, damage may occur if wires are connected in reverse.

The AC output wires shall be at least 3AWG, and temperature rating not less than 75°, and

copper wires.
