As RVing families continue to want more luxuries for their lifestyles, the Parallax ALS 20 Automatic Load Shed Device assists electrical systems to safely & efficiently operate more items from a limited number of circuit breakers. The ALS 20 is made to automatically turn off a secondary load during a high power situation. This lets two high current devices be connected to a single 20 amp breaker.
Typically the ALS 20 is designed so that when an on-demand current is at very high status, it will automatically shed, or sever a secondary load such as a water heater whose functioning can be temporarily held without adversely affecting the user. This would normally happen when a high current drawing device such as a microwave or hair dryer are turned on. 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. When the current demand drops, and is followed by a short safety delay, the ALS 20 will automatically turn the disconnected load back on. It is completely automatic and no maintenance is required.
