Aluminum Wiring is Great When Connected Properly
Aluminum wire is now used in several locations for larger electrical circuits, and is safe and reliable when installed and connected correctly.
Aluminum wire may be used in non-restricted locations with wiring devices specifying the AL-CU designation. Splicing aluminum wire with copper wire requires the use of an anti-corrosion inhibitor and approved wire connectors.
