The ALS 20 automatic load shed is designed to automatically switch off a secondary load in a high current situation.This allows for the connection of two high current devices to a single 20 amp breaker.
Typically the ALS 20 will be configured so that when an on demand current is at a very high level the ALS 20 will automatically shed, or disconnect a secondary load such as a water heater whose operation can be temporarily postponed without directly affecting the user.This situation would normally occur by activation a high current device such as a microwave or hair dryer.In addition, the ALS 20 may also be installed to allow for the operation of more than 2 thermostatically controlled devices on a 120V 30 Amp service.
After the current demand drop, and a short safety delay, the ALS 20 will automatically switch the disconnected load back on.
