wiring across joists
Per NEC, can romex wiring be run across the faces of ceiling joists (stapled
to the faces) if a suspended ceiling will be installed? (or do I have to run between joists and drill through as needed?) Thanks |

wiring across joists
It totally depends on your local by-law office rules.
Ours allows stapling wires under the joists as long as a 1" X 4" board is nailed parallel to the wires to 'protect' them. I have no idea what protection this gives - I would have thought they would require a wooden box (or metal raceway) type barrier to 'protect' the wires. "JC" wrote in message link.net...

wiring across joists
I was once told by the local building inspector that the purpose of
the 1" X 4" board was to prevent you from hanging anything on the exxposed wires. This was only a requirement if a permanent ceiling (drywall) was not going to be installed immediately. (This was in a basement of a new house that I had the builder prewire so that I could finsish it in the future). He insisted that it was guaranteed that me (or my wife) would eventually hang something (like a coat hanger) on the wires for expediency. Seemed pretty anal to me at the time but it didn't take much effort for the builder to nail up some scrap siding and the inspector was happy. After he left the builder (30 yrs. experience) muttered, "that guy was flipping hamburgers three weeks ago and now he's telling me how to do construction".

EJ When I built new garage I had an issue with this since the wiring I put in was suppose to be temporary(2 years). I wanted to staple the wires on the bottom of the ceiling joist. AT first they said I had to drill the joist, then I got them to let me run it over the top of the ceiling joist. Anyway when I get through there will be 4" wireway around the perimeter of the shop with all wiring done from there. |

was suppose to be temporary(2 years). I wanted to staple the wires on the bottom of the ceiling joist.

Anyway when I get through there will be 4" wireway around the perimeter of the shop with all wiring done from there. When you wire a shop, laboratory, or modern office that kind of approach is the way to go. I have installed perimeter raceway in those occupancies as well as in museums and historic homes. The raceway is available in a cross sectional dimension that lends itself to being installed in place of baseboards so that you can have any outlet at any point along the wall line. If I should ever have a custom home built I think I may install it in every room. -- Tom H |
