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.

    I have a halogen lamp that I have rarely used. I found it was not working so took it to a Hardware store to get the right halogen light bulb thinking it had ‘burned out’ The store clerk noticed that the electrical cord had a melted spot and figured that the wiring was probably damaged. How do I connect the wires after cutting them? I could splice then like twisting them together in a straight line (probably not secure enough if accidentally pulled or I could make loop them together by bending each wire backwards (onto itself), hooking them together, then twisting each wire around itself, then taping wire with electrical tape. There is a 3rd way using electrical connectors which I do not have and cannot buy at this present time. I’m very tempted to do the hooking type, but I’m not sure if doing so will cause overheating of each wire or cause more resistance in each wire. Please help me to figure this out. Thanks in advance for your consideration of this request. I await your answer. Thanks again.

      Hi Kyna,
      The concern that I would have is why there was a melted area of the electrical cord. This may be an indication that the cord is actually not the right size for this light fixture, which could lead me to think that the light fixture may not be safe. As for repairing a cord for a light fixture, I would only reccomend replacing the whole cord with a new one because all electrical splices must be enclosed inside a protective enclosure. Consider taking the light fixture to a light fixture repair shop and have their technician evaluate the situation with special attention to the melted cord. The light socket should be examined to make sure the correct size lamp has been used as well.
      I hope this helps you.
      Be Safe,
      Dave
