120/240VAC, 100 amp
ITS100R, LPT100Safely connect an inverter and an AC generator to the same house wiring. Switch can be used with inverters that do not have built-in transfer switch capability. If the generator is not running, the inverter is connected to the house wiring. When the generator is started, the house wiring is automatically disconnected from the inverter and connected to the generator. A time delay feature allows the generator to warm-up before the transfer takes place. DC coils on relays eliminate chatter on low voltage.
Also can be used to transfer between an RV generator and "shore" power.
If system is 120VAC only (no 240VAC) you must connect to "HOT 1" on this switch. Connecting to "HOT 2" is optional.
