I just purchased a new house and noticed that there are romex wire & thermometer wire going perpendicularly inside a cold air return.
This particular cold air return is simply a cavity between the floor joists covered with a sheet of metal.
Does this meet the electrical code in Ontario?
Also, the same cold air return is right below the fridge in the kitchen.
I'd like to run a copper tubing through this space so that I can install a fridge water line through the kitchen floor.
Is it okay to run a copper pluming pipe through the cold air return?
My understanding, you can run pretty much anything through there. As long as there are no connections or terminations hidden in there. So a straight wire in, then through, then out is not an issue.
