Subfloor


I am getting ready to put down a subfloor in my attic and I have ran into a problem. There is a group of wires running across the middle 1/3 of two joists. I know its agaisnt code to notch in this area and was wondering if anybody had any suggestions. There are probably 8 wires including the 220 for the heat exchange. The joists are 2x12s, 16" OC, 20' span. Any help is appreciated.

Subfloor


We'll go on the assumption that the ceiling joists that make up the attic floor are spanned adequately for use as a floor system....

You could install 1x2 or 2x2 furring strips on the top of the joists to raise the floor level up a little. Just use some metal plates to protect your wires!

If you cannot use the strips idea then but a junction box at each end and drill through the joists to reconnect. This is a much harder task then adding the strips. Which will also stabilize the floor a little.
