electrical question - Can romex be run though ceiling joists ?
I have a flat roof territorial style home with 2 x12 ceiling joists though
out the home. This is also a slab home...so no basement or attic to work in/through. If I run additional electrical outlets/circuits/lines...can I drill a 1/2 to 3/4 inch hole along the path of my wiring in the ceiling joists to extend my romex to whatever location is planned ? Otherwise...how do you do something as simple as installing a ceiling fan circuit in any room ? Thanks, Tim R |

Thanks, Tim R It can be done, HOW EVER drilling holes in the middle of a bearing span is NEVER a good idea. everything you drill will be come a 2 x 10. Better get someone to look it over. Surface conduit, wiremold can be used. You do know that a ceiling fan box is a special box attached to the structure. RIGHT? |

Drill as close to the middle of the joist as you can. aem sends.... |

perfectly fine to drill it, just stay at least 2 inches from the edge

Drill as close to the middle of the joist as you can. aem sends.... Code does limit the amount of cross sectional area that can be removed by a hole (sorry I forget the limit but it should be well within what you describe). Incedently, notching is generally worse than holes WRT loss of structural support. Far less notching is allowed than a hole. If these beams are exposed, it would probably look better with a conduit even though that is not required. Running along the wall then against the side of one joist would also limit the visible portions of the run and eliminate most of the holes for just a few $ more in wire and staples. One could even nail up some furring strips to form a channel then cover with some trim to completely hide the wire. Just some more ideas |

If you like, I can send you a pdf showing limits on drilling & notching
based on IRC 2000. TB |

In article gv0Uf.20$x11.18@fed1read10, says...

Thanks, Tim R Here is a link to the joist boring guidelines: http://www.tileyourworld.com/constru...oringGuide.pdf In general, bore holes in the center of the joist, not near the top or bottom, and it is better to place them closer to the ends of the joist rather than out in the middle of the span.

If this were true, then electrical work in much of America would become a big deal. Drilling a small hole in a 2X12 doesn;t make it a 2X10, any more than the occasional knot or other imperfection in lumber used for construction. |

Is this true for solid wood joists? It is definately NOT true for I-joists. For I-joists, you can put a hole up to 1.5" in diameter anywhere you please - in fact, they come wth pre-stamped 1.5" knock-outs about a foot apart all along their length. For larger diameter holes, there are guidelines as to how close you can be to a bearing surface - the larger the hole, the farther you have to be from a bearing surface. -- Calvin Henry-Cotnam "I really think Canada should get over to Iraq as quickly as possible" - Paul Martin - April 30, 2003 ------------------------------------------------------------------------- NOTE: if replying by email, remove "remove." and ".invalid" *** Free account sponsored by SecureIX.com *** *** Encrypt your Internet usage with a free VPN account from http://www.SecureIX.com *** |

Just for added thought..
Romex or at worst conduit can be hidden behind moulding, either baseboard or crown or anything else you like. There are also commercial products that are moulding raceways and have seperated sections for low and high voltage cables. I don't recall any names but try Leviton.com and similar. RickR |
