Circuit for exterior GFI's


I am completely re-wiring a house in Ontario Canada and wanted to know if the 2 GFI protected receptacles I am putting on the exterior walls have to be on a separate circuit or can be combined with an existing circuit for other interior lights, plugs, etc.

They can be on another circuit. Keep total load in mind though. Often power and garden tools are used on outside outlets and have a fairly high amp pull.

The outdoor plugs need to have their own circuit. They cannot be tied into anything on the interior of the house. Also make sure if you installing two gfci receptacles you don't run one of them off the load side of the other. If you run off the load side just use a regular receptacle.

Somehow I would have guessed that...that is why I didn't answer. I actually kind of like that rule.

Let me ask you this, is there something specific you guys use outside to justify this requirement? Because I don't see any added safety by requiring this, more of a design choice which should not be enforced on anyone. (Not that the NEC would ever violate ones wallet and force something ridiculous to be installed. )

ya i really have no idea why its like that, i mean a pressure washer can draw a fair bit but on the whole i guess they just figure anything you use outside like and electric mower or weed eater will have a large draw.
