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. Jim Hester says:

    My daughter has a light fixture over her bathtub/shower, and the bulb has burned out. I cannot figure out how to replace the bulb. I guess you would call the fixture “recessed”: The glass globe extends about 5 inches down from the ceiling, and is flat on the bottom. There is a trim ring as well at the ceiling. I can pull the fixture down to expose the inside, and can see the little v’shaped wires on two sides that hold the fixture in place. Beyond that, I am at a loss. Can the globe itself be removed somehow to replace the bulb? I’ve turned, pulled, twisted, spun, etc…but no luck. Thanks for any help!

  2. Dave Rongey says:

    Yes Jim, those V-Shaped wires support the trim piece for the recessed light. Carefully squeezing theses wires together will allow the wires to be removed from the guides inside the recessed light. Once the trim piece is remover then you will have access to the light bulb. Be sure to use the same watt bulb to prevent the recessed light from over heating.

  3. Mrs mortenson says:

    Our home is 30 years old with recessed heat lamp vents in the bathrooms. What did we do wrong when they were installed to have a draft when the wind blows? They are vented into the ceiling and then to an outside fascia. If that was a correct way to install them then how to we stop the loss of warm air when the vents are not in use?

  4. Dave Rongey says:

    Hi Mrs M,
    What I suspect is that there is a problem with the back draft flapper. Where the exhaust duct connects to the housing of the vent unit there is an adapter which should have a flapper. The flapper is designed to open up only when there is exhausting air flow. The flapper also prevents a back draft by staying closed when the vent is not in use. If the flapper is missing or is not mounted into the adapter properly then it will not work correctly and this may be why you are noticing a draft.
