Safe Practices with Aluminum Electrical Wiring
Summary: Safe Practices with Aluminum Electrical Wiring.
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.
There are restricted areas, and some types of structures where where aluminum wire is not permitted. Please check with your local building authority for information about installing aluminum wire for your application.
The Safest Way to Test Electrical Devices and Identify Electric Wiring!
The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
