I am planning on hooking up a hot tub in our in backyard and we need to run a wire from the breaker panel to the tub. Although we could run the wire through the concrete, there is an unused basement window and it would be easier to run the wire through the window or its frame.
I imagine other people wanting a hot tub may also have a similar situation. I've attached a picture of both sides of the window for reference. I've also attached a picture of another location in the house where someone has done exactly as described.
Is it okay, as for as the ESA (Electrical Safety Authority) in Ontario (Canada) goes, to run the electrical wire for the hot tub through this window?
