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. Vertice Green says:

    I purchased a home that required minor repairs. Among the repairs were replacing the lighting fixtures in the bathrooms. I purchased a new light fixture from Lowes. Each bathroom has two light fixtures. The first fixture has two black and white color lines, but the second fixture has only one of each line. After replacing the light fixtures and restoring the power only the second fixture works. There is no activity from the fixture with two lines. Please help me understand what have I wired incorrectly?

    • Dave Rongey says:

      Hi Vertice,
      First, be sure the light bulb in the first light fixture is new or good.
      Next, make sure the wiring of the first light fixture is made where the wires are connected color to color, that is: the black wires together, and the whites wires together, and the same for the ground wires.
      Also be sure that one of the wires from the light fixture to the line wire splices has not slipped out of the wire connector, which is a very common and easy mistake to make, but very easy to fix.
      Enjoy your new lights,

    Will a Ground Fault Circuit Interrupter or Residual Current Device(termed in USA) help in making my home safer for electrical accidents?

    • Dave Rongey says:

      A Ground Fault Circuit Interrupter will help prevent electrical shock in areas where required, such as bathroom outlets and kitchen counter top outlets and outdoor receptacles to name a few.
      Equally important are the AFCI or an Arc Fault Circuit Interrupters, which will help prevent fires when an arc is detected, and are required for new circuits in areas including bedrooms.
      Both the GFCI and AFCI require either a special circuit breaker or receptacle, and the circuit wiring must be appropriately configured as well.
