Can I plug a 220v timer for my light into an oulet rated for 110v? I don't know for sure what the outlet is rated for,(google says canada is 110v outlets) currently plugged in is my furnace, an extention cord with a 600w mh/hps, small oscillating fan, and a space heater for when lights go off. If I plug furnace into a different outlet, and move extention cord to a different outlet, can I plug a timer (220v) into the outlet and have only the light going to it?
