*Note: If Ground Fault Circuit Interrupters (GFCI) circuit breakers, Arc Fault Circuit Interrupters, or Surge Protector Circuit Breakers were used as the branch circuit protector

in the main load center, they MUST be used in the transfer switch. Because these circuit breakers typically take up more than one space, the overall maximum number of

circuits may be reduced from the number shown.

STEP 1: PLANNING YOUR INSTALLATION:

Determine the appliances, circuits or equipment you want to operate with generator power during a power outage, such as:

•

Refrigerator/Freezer,

Furnace Blower (gas/oil only)

•

TV / Radio

•

Lighting

•

Water Heater

•

2. Determine the amps required for each appliance by reading the label on the appliance. IMPORTANT: No appliance should have an amperage rating that

exceeds the GEN MAIN breaker rating in the transfer switch (See Table 1). The total amperage of all circuits can exceed the generator rating, but not all

circuits will be able to be used concurrently.

3. Assign the circuit # in the load center to a circuit (A2, B2, etc.) in the transfer switch matching the size of the circuit breaker in the load center to the

circuit breaker in the transfer switch. Once you've determined which circuits you want to connect and the appropriate amperage, you will be ready to

begin installing your transfer switch.

4. The location of your load center/electrical panel in your home or business will determine where the transfer switch will be installed outdoors.

STEP 2: INSTALLATION PROCEDURE:

HAZARDOUS VOLTAGES ARE PRESENT INSIDE TRANSFER SWITCH ENCLOSURES THAT CAN CAUSE DEATH OR SEVERE PERSONAL INJURY. FOLLOW PROPER INSTALLATION,

OPERATION AND MAINTENANCE PROCEDURES TO AVOID HAZARDOUS VOLTAGES. TURN OFF THE MAIN CIRCUIT BREAKER IN THE LOAD CENTER BEFORE STARTING INSTALLATION.

I. TRANSFER SWITCH INSTALLATION:

Transfer switch can be installed on either the left or right side of the main load center. Transfer switch is provided with 21-1/2" of flexible conduit.

The connection to the main load center, using the provided wire harness, must be made through one of the two (2) knockouts (KO's) provided in the
