Aluminum branch wiring was used during the 1960’s and 1970’s for the wiring of receptacles, switches and devices throughout many homes. It is particularly common in Subdivision homes built in the 1970s in the Erie County and Southern Ontario area. Many individuals believe that the aluminum wiring should be removed and replaced with copper. This is not always the case, and there are approved or recognized methods for making the system safe. If single strand aluminum wire is present (#12, #10 Gauge, General Purpose Branch Wiring) it is important to install or verify proper connections of all devices and terminals throughout the house. Copper wire ends, known as ‘pigtails’, can be installed at all terminals. Wire nuts are not approved for pig tailing, and according to many licensed electricians, may pose an even greater fire hazard and should be replaced. Keep in mind this does not apply to the main service lines that may be aluminum and are covered in thermal paste. These lines are connected directly to the service panel and thermal creep does not affect these heavy duty connections. |
