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. John Sparks says:

    I want to use an industrial grade extension connection to connect my Breaker Box to my generator. Since under normal conditions the corded 4 wire receptacle that will be wired into the box will be locked out and tagged out, do I still need a transfer switch? Under emergency usage the main breaker would be turned off and the generator plugged unto the box through the the corded extension coupling.

  2. Dave Rongey says:

    Yes John, you still would need a transfer switch or interlock that would disconnect the electrical utility while the generator is supplying power. It is vitally important that only one source of power may be in the ON position at a time, and the only way this can be accomplished is by using an approved transfer switch device.

  3. Generators says:

    I agree with your tips but I have a question. I bought a 5 KV generator and am also using circuit breakers but recently 2 times my circuit breaker burned can you tell me why?

  4. Dave Rongey says:

    Hi Bill,
    Make sure you are using the right circuit breaker for the panel. Off brand circuit breakers may not fit correctly and be very careful, there are some name brand circuit breakers that are imposters, complete with UL labels and everything – but they are made in some other country with inferior materials and workmanship.
    Other than that make sure to check your loads, and if you are using a 2-pole circuit breaker make sure the load is balanced on both legs as much as possible.
    If the panel buss has burnt due to a bad connection do not put a new circuit breaker in the same place because the connection will not be solid and tight. It is best to install a blank spacer or breaker that will not be connected to avoid future problems.
