*Note: Arc Fault Circuit Interrupter (AFCI) or Ground Fault Circuit Interrupter (GFCI) circuit breakers can take up more than one space; the maximum number of circuits may be
reduced from the number shown. If you relocate an AFCI or GFCI protected circuit from the panelboard to the transfer switch, the AFCI or GFCI MUST be relocated to the transfer
switch; install the AFCI or GFCI in the right side of the transfer switch, next to the neutral bar. Connect the panelboard neutral (pigtail) wire to the transfer switch neutral bar.
Connect the load neutral in the panelboard to a -6 ft-12AWG piece of white wire, run through the conduit to the transfer switch and connect to the "LOAD NEUTRAL" terminal on
the AFCI or GFCI. See AFCI and GFCI Installation in a GenTran Manual Transfer Switch at www.gen-tran.com for complete AFCI and GFCI installation instructions.
**Note on 300660: This unit is rated for 120 VAC loads only; single pole circuit breakers should be used in this unit. Total load must not exceed 3750 watts.
TYPICAL INSTALLATION AND PROPER GENERATOR LOCATION:
NEVER run portable generators indoors or in garages, basements, or sheds. While operating, portable generators should always be used at least 5 feet away from
windows, doors, vents, or any other opening. Carbon Monoxide (CO) from a generator is deadly and can kill you in minutes.
STEP 1: PLANNING YOUR INSTALLATION
1. Determine the appliances, circuits or equipment you want to operate with generator power during a power outage, such as:
• Furnace ,
• TV / Radio
• Refrigerator
• Cordless Telephone
• Freezer
• Garage Door Opener
• Microwave Oven
• Water Heater
• Well Pump
• Security System
• Sump Pump
• Computer, Fax and Printer
• Lighting
• Range
2. Determine the amps required for each appliance using the CB rating in the load center. No appliance should have an amperage rating that exceeds the “GENERATOR
MAIN” rating in the transfer switch. 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 (A1, B1, A2, B2, etc.) in the manual transfer switch, matching the size of the circuit breaker in the load center to the circuit
breaker in the transfer switch. Complete TABLE 2; you are ready to begin installing the manual transfer switch. NOTE: the transfer switch can be expanded beyond 16
circuits by connecting a subpanel to the sub-feed lugs located at the bottom of the bus. See Fig 2.
