Thanks for your electrical wiring question Dan.

How to Check for the Cause of Incorrect Voltage

Application: Evaluating Incorrect Voltage of a Home Electric Circuit.
Skill Level: Advanced – Not Recommended for Homeowners or DIY’ers – Best performed by an Experienced Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester and amp meter or load recorder.
Estimated Time: Depends on the type and age of the electric service panel and the access to the circuits to be evaluated.
Caution: Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock.
Notice: Making changes to the Home Electrical Service Panel should be done according to local and national electrical codes with a permit and be inspected.

Testing Procedure to Locate a Voltage Problem

IMPORTANT: Voltage Testing inside an electrical panel is not recommended for anyone who is not an experienced electrician. The following is an example of the various testing procedure a qualified electrician may use to help locate a problem with incorrect electric circuit voltage.

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.
