Overview of Splicing Electrical Wires


splicing electrical wires 0
Summary: Before splicing wires it is essential to understand the NEC Electrical Codes that apply to the specific circuit application. Next, we must select the proper electrical wire, junction box, and the type of electrical connectors that will be installed. Finally, to put the project together it is best to select the proper tools that will ensure the method of wiring is performed correctly as well a providing safety for the electrician.

The Electrical Box
The type of electrical box where the wiring is installed will depend on the type of devices to be installed and the specific location of the application. For example an interior electrical box may be different from an exterior electrical box. The type of box that will be used will depend on the specific type of surrounding construction method and environmental factors such as exposure to weather elements.

Approved electrical boxes must be selected which provide enough space for the number of wires that will be installed and the type of device that will be installed.
See more about types of electrical junction boxes.

The correct size wire connectors must be used for each wire splice.
See more about electrical wire and wire connectors.

After the splice is made be sure to cap off any remaining wires.

Electrical Codes for Splicing Electrical Wires


The following NEC Electrical Codes are an example of the codes that may apply to Splicing Electrical Wires for Home Wiring Projects.

314.19 Wiring Methods junction boxes accessible Junction boxes shall be installed so that the wiring contained in them can be rendered accessible without removing any part of the building.

314.16 Electrical Junction Box Fill - The volume of electrical boxes shall be sufficient for the number of conductors, devices, and cable clamps contained within the box. Nonmetallic boxes are marked with their cubic inch capacity.



NOTE: This is a partial list of electrical codes. Other codes may apply. Some codes may be updated.

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.
