How to Make an Electrical Cable Splice

How to Splice Electrical Cables: Where the cables enter into the junction box will depend on the cable orientation, however I have found that it is best to enter at the same side in order to line up the conductors evenly for the splice.

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. Kelly says:

    We are replacing an older range with a “new to us” model. The power cable/cord is too short. Can we swap the power cables between these two ranges? If yes, do you have tips, tricks, directions, or cautions for us? If no, how can we resolve this? Moving the power receptacle is not an option.

  2. Dave Rongey says:

    If both of the range cords are the same, except the original is longer, then yes you can swap the two cords. Pay close attention to the wiring configurations. There is more help for you at: Wiring a Range Cord

    I need to splice in a wire from a new motion light into the feed wire in my garage.
    The feed wire is old and may be cloth, it is coming down one of the rafters and contiuing on back to my workbench. How should I splice in the new wire?

  4. Dave Rongey says:

    Hi Alan,
    The wire splice should be done inside an electrical junction box or enclosure. If the junction box you choose is metal then insulated bushings should be used to protect the wiring as it enters the openings of the box. Be aware that open electrical wiring that is not protected in a garage should be covered with sheet rock and protected, or the wring may be installed into an electrical conduit. Wire connectors must be sized appropriately for the size wire that is used.

  5. Keith says:

    My wife has sewing machine from Europe, it is 220 volt with a round two prong plug. Is there anyway I use this machine?


  6. Dave Rongey says:

    Hi Keith,
    Because this device has a motor I would suggest locating a specific voltage adapter that can be used for the specs indicated on the sewing machine.

    I Hope this helps,
