Electrical Question from Mike about Electrical Wiring
Question: This house was built in 1947. I want to replace some outside lamps: the new lamps have insulated black and white wires and a bare copper wire.
The wiring coming out of the wall looks like two black insulated wires and no copper or bare wires. No third wire at all. No lamp mounting base either; the house wire just comes out of a drilled hole in the wall. What’s my next step?
Thanks for your electrical question Mike.

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.
