For a generator to power the house safely, you need a transfer device. We install the transfer switch, the outdoor power inlet and, for standby generators, the complete hookup. We choose the essential circuits with you based on the generator’s output.

The cases we see most often, and what we do.
Keep backup heat, the well or sump pump, the fridge and the lights during a long outage: we choose the essential circuits based on your generator’s output.
Never through a regular outlet: it’s dangerous for you and for line workers. We install an outdoor power inlet and a transfer device, and show you the procedure.
A backup plan that is set up and tested with you, so you don’t find the problem during the outage.
Automatic transfer switch, complete hookup, coordination with the gas supplier and the unit installer: the house restarts by itself.
Milking, ventilation, refrigeration, checkout: we identify what must stay powered and size the transfer accordingly.
Get your bearings before you call
Start from a profile or check what you want to keep running during an outage. We add up your appliances’ running watts and the start-up of the largest motor, using the average values from Honda Canada’s guide.
Check your appliances: the result appears here.
A motor’s start-up only lasts a moment: we count only the largest one, starting motors one at a time. Average values. Your appliances’ actual values are on their nameplate (watts = volts × amps). We confirm the calculation with you before you buy.
