Our (New Jersey) house is a split-level, and the main load-center for the house is in the garage. We are installing a new sub-panel in the (1/2 below-grade) basement on the opposite side of the house. To avoid messing up the interior, we are running service cable (SER 3-3-3-5) outside, under the eaves, along the exterior of the house, and then down to the basement, to reach the new panel. Probably because of stupidity, the new sub-panel is not on the basement exterior wall through which the cable will pass into the basement, but several feet away.
Does anyone have suggestions how pass the cable through the wall(s), and to protect the cable and guard the basement (and garage) against humidity/elements ?
I asked my town inspector what he would like to see: he said 'make a hole,' which I can do, and add some electrician's sealant putty to insulate. I suppose this is pretty much in line with Getting Ethernet Cable Through Exterior Wall but....
The (1/2) below-grade basement, 7-foot high, exterior walls consist of foundation blocks. These walls are crowned with 2 horizontal 2 X 4's (the 'bottom plates' - I am sure the incorrect term), 4'' sides face down, upon which rest outward-facing 8 X 2's and the cross-beams for the floor above. I was planning on passing the cable through the 8 X 2 (i.e., to have the cable high as possible) - the inspector is OK with this.
The garage wall is the 'usual' above-ground wall, made with 2 X 4 s, with sheet-rock on the interior and shingles on the outside.
Thank you for your time,
