All Professional Industries - Manufacturer of the LOAD SHED A/C™


Generator Load Shedding:

The Load Shed A/C™ allows two or more large air conditioners to operate on a generator sized for only the largest one air conditioner. When utility fails and the transfer switch flips down to generator power, the Load Shed A/C will shut off one air conditioner while allowing the other to operate until the adjustable timer expires. The Load Shed A/C will then allow the second air conditioner to operate on the adjustable timer. When the second timer expires, the process will start over again with the first air conditioner until utility returns.

The LOAD SHED A/C PLUS™ has all the same adjustable components as the Load Shed A/C, plus it will turn off circuits as large as 100 Amps automatically while on an automatic generator system.

Each Load Shed A/C Plus rotates 2 air conditioners on the adjustable timer and turns off any size load up to 100 Amps/600V automatically while on an automatic generator. Use up to 9 Load Shed A/C Plus' on one generator system.

Save $thousands$ with the Load Shed A/C by reducing the generator size needed to power your air conditioning during an outage.

Provided Functions:

Automatic load reduction to match the generator supply.

Each Load Shed A/C allows for 2 of any size air conditioners to alternate operation with a adjustable timer while on generator power automatically. During utility, both air conditioners operate normally.
As many as 9 Load Shed A/C’s may be connected to each generator system, controlling up to 18 air conditioners at once!

Installation Information:

The Load Shed A/C requires 1 Installation Kit, 1 conduit and 2 low voltage thermostat wires.

  • A control line from the transfer switch to the Load Shed A/C.
  • Thermostat wire – Only 1 pair wire is needed from each thermostat. That 1 pair wire from each thermostat is normally closed in utility and opens and closes on the adjustable timer during an outage using the Load Shed A/C on a generator with an automatic transfer switch.

Custom Load Sheds are available.
