One of my projects for when the weather warms is to install a doorbell in this old house. I'd like to know what the safety/legality is of using doorbell wire along the outside wall.
The local bigbox hardware store has 75' rolls of 'bell wire', and I think the easiest & most out-of-sight route is down the door frame and under some moulding around to a basement window (I can't go in through the wall).
The wire is 3 conductor with an outer sheath, but it does not specify indoor or outdoor use. Is there any code (Canada) regarding exterior cable in low-voltage applications such as this?
