Electrical Wiring to a Porcelain Lamp Holder
Can I use 18 gauge thermostat wire to connect from the Romex to the Lamp holder?
Electrical Question from Greg about Light Fixture Electrical Wiring
Background: Greg, a Homeowner from Ewa Beach Hawaii
Question: I want to install a ceiling light. I have a wall stitch, and the ceiling box has romex line (White/Black/Red and bare copper). All that is original home construction. I have a porcelain Lamp holder that has a brass color screw and a silver color screw. Can I use 18 ga. thermostat wire to connect from the Romex to the Lamp holder?
Thanks for your electrical question Greg. Absolutely Not! Thermostat wire is rated for low voltage wiring applications only. You may consider purchasing fork tongue connectors that are rated for the gauge wire that you have. These connectors will slide around the screw terminals nicely and can be crimped onto the same gauge stranded wire that is spliced to the solid Romex wire. By the way, the Brass Screw is for the Power wire, and the Silver Screw is for the Neutral wire.

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.
