Purple wire nuts9/1/2023 ![]() * flickering of lights not traceable to appliances or obvious external causes. ![]() * Strange or distinctive odor or the smell of burning plastic in the vicinity of a receptacle or switch. Trouble signals associated with aluminum wiring problems include:.If aluminum wiring was used, have the electrician or individual check the connections on heavily loaded and constantly loaded circuits to determine if the electrical connections have been made properly or show evidence of deterioration. If you are not certain, or if you do not know whether the home is wired completely with aluminum, ask a knowledgeable electrician or other qualified individual to make the determination.SERIOUS OR FATAL ELECTRIC SHOCK COULD RESULT. To assist consumers who live in homes with aluminum wiring to reduce the potential risk of fire and the possibility of dangerous overheating, the United States Consumer Products Safety Commission suggests the following precautionary steps.ĬONSUMERS WHO HAVE NOT HAD THOROUGH ELECTRICAL TRAINING SHOULD NOT ATTEMPT TO INSPECT THEIR HOME WIRING SYSTEM OR MAKE ANY ELECTRICAL REPAIRS OR ADJUSTMENTS BEFORE SEEKING EXPERT ADVICE. These new devices use terminals made of alloys that are more compatible with aluminum. Ultimately, the rating authorities decided that specially designed wiring devices were needed for aluminum branch wiring, and the electrical code was changed about 1971. The corrosion may not occur if the recommended wiring devices are used. The corrosion causes the resistance between the wire and the terminals to rise, and the rise in resistance causes heating a few isolated cases enough heat to cause the nearby combustible materials to ignite. (Copper wires with brass terminals do not create corrosion because brass is an alloy of copper.) The corrosion forms when two dissimilar metals meeting this case the contact between the aluminum wire and the brass screw terminals on the wiring devices. What was found to be happening was that corrosion was forming on the surface of the aluminum. This repair method is considered unacceptable by the Consumer Safety Products Commission for solving the problem of overheating aluminum wiring circuits.Įven though it is common, we are of the opinion that “safeguards” to the system should be made to ensure the system is safe.
