In the course of inspecting a home, I often find open electrical splices in the crawl space and attic, and I cite them in my report. A splice, in layman’s terms, is a connection between two or more wires. These splices are normally made with a small plastic device resembling a thimble that is called a wire nut. The wire nut is twisted onto the wires, and holds them tightly together for a good connection. In accordance with accepted electrical practice, all splices must be inside an approved electrical box with a cover, and this box must be attached to the framing of the house and accessible. These boxes are either metal or plastic. The reason why splices must be inside a covered box is very simple. When electric wires become loose or overloaded, they can get very hot, and, in some cases, throw off sparks. If the wires are out in the open, they can drop sparks onto combustible materials or otherwise cause them to ignite. The electrical box is designed to contain the heat and sparks long enough for a fuse to blow or a breaker to trip. Crawl spaces are not very nice places to work, and the person doing the wiring is probably in a hurry to get out of there, and not interested in going back to place a cover on each box. Open splices are an invitation to disaster, and should be corrected as soon as discovered. If you suspect that your home has open splices in the crawl space or attic, have a qualified electrician correct the problem as soon as possible. 11/1/2004 12:00:00 AM
