Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

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 that I use to easily Detect 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.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

  1. David Yurick says:

    I have a question regarding knob and tube wiring. Is there a safe way to wire a 15 amp GFCI outlet to knob wiring?

    Thank you.

  2. Dave Rongey says:

    Hi David,
    Yes, a GFCI outlet may be wired to knob and tube wiring as described in the instructions found in the article: Knob and Tub Wiring and GFCI.
    To help verify the polarity of the knob and tube wires a non-contact voltage tracer may be used.
    The label which comes with the GFCI outlet must be applied to the face of the outlet which states that the outlet is not grounded, however the GFCI circuitry will still provide ground fault protection.

    Be Careful.

  3. Chris Payne says:

    I would like to add a lamp to a ceiling fan. After removing the cap covering the wiring I see a white wire (common?) and a blue wire which I think might be the hot wire. Please advise,
    Chris Payne

    Hi Chris,
    The Ceiling Fan Blue Wire
    These typical the light fixture wires found on most ceiling fans:
    The blue wire is the power, and the white wire is the neutral.
    I hope this helps,
