Underwriters Laboratories, Inc. (UL) lists these devices especially for use with aluminum wire, although they can be used with copper or copper-clad wire. It has been determined that CO/ALR devices perform better with aluminum wire when installed carefully and according to best electrical practices than do the types of switches and outlets usually used in the original installations of aluminum branch circuit wiring.
Advantages:
- All connections will be cleaned of debris and devices will be checked for prior damage.
- All “old technology” devices will be replaced with new aluminum approved devices.
- Every connection will be completed using best electrical practices and be tight.
- This repair will reduce the hazard risk of aluminum wiring.
Disadvantages:
The CO/ALR replacement repair is considered an incomplete and impermanent repair. Not every connection can be replaced as a CO/ALR device (such as GFCI’s and permanently wired appliances and ceiling mounted light fixtures) and these connections can loosen up more than copper connections creating hazardous gaps.
CO/ALR Devices
Underwriters Laboratory lists CO/ALR devices primarily for use with aluminum wire because they use special metals at the terminal areas that are compatible with aluminum wire.
CO/ALR wiring devices, like the one shown above, have special terminals designed just for aluminum wiring.
