resEstimating Power Needs

Back up generators can supply emergency power to help keep important equipment running in a power outage.

It is very handy to know how much power certain appliances need as you do not want to blow up your generator especially when you need it the most.

The chart below contains examples of household appliances you can power with a portable generator. 1000 Watts = 1KvA.

Always remember to keep your back up generator a safe distance away from the house, with the exhaust directed away from any doors, windows and vents. Generator exhausts contains high levels of carbon monoxide gas which can be dangerous or even fatal if inhaled.
