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. Eli says:

    To hook up a hot tub do I need a disconnect or a shut off switch or both?
    Thanks for time and attention.

  2. Dave Rongey says:

    Hi Eli,
    A disconnect actually shuts off the circuit power and is required near the hot tub. The circuit must be protected with a GFCI breaker.
    The hot tub itself may have a shut off switch for functions like an air blower etc.
    I hope that helps,

  3. carol says:

    Can you confirm what the regulations are regarding a safety cut off switch, or electrical isolator on a hot tub used by the public not just for personal use.

  4. Dave Rongey says:

    Hi Carol,
    Because of the number of Article Exceptions that are written into the electrical codes, each hot tub project will need to be reviewed individually where all of the environmental factors may be identified as well as the codes that will then apply.
    For example, please refer to NEC sections 680.43, 680.62, and 680.74 for more information, and then make application for your specific area or location.
    I hope this helps,
