The Auto Interlock IV is a 4 pole, 50 ampere power transfer relay which automatically transfers the 120 volt A.C. from the shoreline to the auxiliary generator when the generator is started. A time delay is provided to allow the generator output to warm up and stabilize before transferring the load. Timing is adjustable from 2 seconds to 10 minutes. In addition, indicator lights are provided to indicate which input is active and is being supplied to the load. When the generator is down, the load is returned to shore power. Easily installed, the unit operates completely automatic, requiring no operator intervention.
