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.

    Hi Alex,
    Although my new Home Electrical Wiring book is quite extensive I have not included information about Estimating Electrical Jobs or Projects, however I am seriously considering making a separate book for Electricians, Contractors, Inspectors, Handymen and Handy-Women and include how to estimate electrical jobs including labor and materials.
    Thank you for your interest.

  2. Alex says:

    Hi Dave,
    I would like to know how to estimate electrical wiring jobs including the wiring materials and particular knowing the quantity of cables and materials that are needed. Can I get such guidance in your book Complete Guide to Home Electric Wiring?

    Thanks Very Much, Franky!
    Sorry about the delayed reply, but I have been swamped, so I’m doing my best to catch up between the website questions and the blog comments. I really appreciate your comments which are very encouraging. I hope you come back and visit often. Additional home electrical wiring information is being added all the time with more on the way, so be sure to spread the word!
    Hey Franky, be sure to use nail safety plates on those 1 1/2 inch nailer strips if you are boring holes to install additional wiring. I know exactly what you are doing as I have installed wiring this way when clients decide to finish off their basements or fur out a concrete or cinder block walls. This method works well, but there is very little safe areas for electrical wiring.
    Thanks Again Franky,

    I have a concrete home that was built in 1944. i was shocked to find out that the r-value of concrete is only r-10 so I have been installing 3/4″ r-5 rated Styrofoam insulation (1 hole sheet tacked with 3/4″ nailers) then 16″ strips of Styrofoam between my nailers 🙂 hopefully getting R-20, but this gives me 2 advantages, insulation and a 1.5″ void to run NEW WIRING 🙂 I run my wiring up from the crawl space and thru conduit inside the walls “maybe an over-kill” but hey better safe than sorry. THANKS DAVE YOU ARE MY HERO 🙂 if I had to pay for all the info I have gotten from you I would might as well hired an electrician. Thanks for the codes and the wiring diagrams you even got me thinking about going to school to get my license cause dang this electrician thing might just be the way to go 😉 Many Thanks

    I recently bought an older home and had a problem with part of a circuit going dead. After investigating I find the problem is due to wires coming out of the back of the recepticle that were just push-ins. Now I am in the process of replacing every recepticle in the house and wrapping the wires around the screws but have found one that even though is turned off in the breaker panel still has .8 volts according to my multimeter. Is there any danger in changing this recepticle out? What precuations do i need to take if any?
