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.

    Good Day,
    I have recently bought an older home which was built in 1990. Just before the air conditioner starts, all the lights in the house dim. Actually I would never have known because the lights are never on during the day, but they dim for a very short period of time of a few seconds when the a/c unit starts.
    This I would presume is due to the load being taken by the a/c unit. Question: is this normal, and if not are there any safety issues that I need to address?

    Thank you,

    Hi Robert,
    Motor loads, such as an air conditioning unit, do require a lot of electricity to start. In fact, air conditioners could draw up to 4 times the running amperage when they start, so when the air conditioner starts you may see some lights dim a little.

    Here are some other things that could cause your lights to dim when your air conditioner starts:
    The size of the home electrical service panel. If the electrical service is too small it may need to be upgraded.
    The size of the home, and other electrical circuit loads such as electric water heater and electric range or cook top.
    Is the home located in a rural area where the electrical utility service is weak, or experiences low voltage.
    The age and size of the air conditioner, and when was the last time it was serviced.
    Has the air conditioner been replaced with a larger unit, and if so, does the new air conditioner require a larger electrical circuit.

    I hope this helps,
