* Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc. Maximum power
decreases about 3.5 percent for each 1,000 feet above sea level; and also will decrease about 1 percent for each 6° C (10° F) above 16° C (60° F) ambient temperature.
** Load current values shown for 120 volts are maximum TOTAL values for two separate circuits.The maximum current in each circuit must not exceed the value stated for 240 volts.
*** Circuits to be moved from main panel to transfer switch load center must be protected by same size breaker. For example, a 15 amp circuit in main panel must be a 15 amp circuit in
transfer switch.
