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. I have a two year old home and the builders have installed an electrical plate on the front of my house about a foot from the ground. They indicated it was for my light post whenever I installed it for a dawn-to-dusk light post. I’m not sure how this works. Do I have to buy a specific light post for this to work?

  2. Dave Rongey says:

    Hi Linda,
    From what you have described the electrician has provided a junction box with a blank cover plate which most likely has wiring that can be used for future outdoor lighting. The electrician should explain what the capabilities are of the wiring and if this is a constant supply of power, or if the wiring leads to a switch box where the additional outdoor lights may be controlled. Installing this for you at the time of construction is in your favor because it provides the capability for outdoor lighting to be added. How this power source is used for future lighting will depend on making decisions about the type of lighting you wish to install and the locations for the lights. This could be for a post light, garden lights, walkway path lights etc., where the power will be extended from the junction box to the desired lighting you choose to have installed.
