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.

    Should I use conduit when wiring for an outdoor spa?

  2. Dave Rongey says:

    Hi JB,
    Electrical wiring and components must be protected according to code, specific to the project location. Typically a GFCI protected circuit for an outdoor spa is installed with a permit and according to applicable codes, and the wiring is installed in an electrical conduit using water proof fittings and methods and the installation is inspected.
    Be Safe,

    I’m inquiring as how much it would cost to rewire my hot tub as I’m moving it 6-7 feet from its current position and require a quote. Yours, Gary

  4. Dave Rongey says:

    Hi Gary,
    An estimate to extend the circuit wiring of a hot tub to a new location would require an on site evaluation where an electrician in your area could see the existing circuit wiring and then propose the best methods to would use to extend the circuit. The project may be estimated with the time and materials necessary, which may include an approved junction box, and supported electrical conduit to protect the circuit wiring. The actual cost for the project will depend on your location, the current rate charged by the approved electrician, and he cost of materials.
    Thanks for sharing your project with us Gary,
