Junction Box Splice for a 220 Volt Electric Range Cable

How do I Splice a 220 Volt Cable in an Electrical Junction Box? Splice Electrical Wires, What to do with the Ground Wire. |
Splice Electrical Wires
Electrical Question: I need to move an existing 220 /240volt outlet to make a new gas and electric range fit when plugged in.
- This outlet is as old as the house which was built in 1971.
- I don’t want to rewire the entire run, I just want to use the existing box as a junction box and run over about a foot to the new location with a plastic remodel box.
- The problem is that there is no ground screw on the plastic boxes.
- What do I do with the ground wire in the new box?
- Do I simply cut if off?
- The existing outlet has three wires, two hots and a neutral I believe as the ground is attached to the box.
This electrical wiring question came from: Dennis, from Olympia, Washington.

Thanks for your electrical wiring question Dennis.
How to Splice a 220 Volt Cable in an Electrical Junction Box
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on the personal level experience and ability to work with tools and access to the wiring.
Precaution: Identify the circuit, turn it OFF and then Tag it with a Note before performing any wiring.
Notice: Installing additional electrical wiring should be done according to local and national electrical codes with a permit and inspected.
Special Materials: Properly sized wire connectors, anti-corrosion ointment, electrical tape, junction box and blank cover.
Working with Ground Wires and Junction Boxes
- Splicing 220 Volt Cable
- Splicing onto the existing cable and extending it to a different location is fine, just make sure to splice all the wires together color to color including the ground wire.
- What to do With Spare Wires
- Never cut off a wire that is not being used especially a ground wire.
- Cap off any unused wires and if the junction box does not have a terminal or there is no provision for terminating the ground wire then do not cut the ground wire off, but keep it folded inside the junction box.
What to do with the Ground Wire
- Junction Box Ground Wire
- I have seen this far too often where the ground wire is cut off really short especially at switch boxes because the switch did not have a ground terminal, however it is best to keep the full length of the ground wire and fold it back into the junction box so that it is available for future use.
- Safe Keeping for Ground Wires
- The ground wire poses no threat even if it is a bare wire as long as the ground wire is folded into the back area of the junction box.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis 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 TesterThis 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 CutterMy 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. |

I was told that the dryer electrical wire cannot be spliced according to the Ontario Electrical Code. It must be continuous from the outlet to the breaker. Is this true?
Hi Tim,
I am unaware of any such code. Electrical splices here in the U.S.A. may be made as long as the splice is accessible and done using approved methods and materials for the electrical circuit and application.

Can I splice a dryer and a range on the same 240 line?
Hi Lenny,
The amperage ratings are different for an electric dryer and an electric range, therefore a separate dedicated circuit is required for each of these appliances.
I hope this helps,
Dave
I want to move my current 220/240 volt outlet (for my range) to a new location in my kitchen, it requires about 15 ft of wire after measuring. Could I just splice it to the new box, or the wire has to be continuous (un-spliced) from the dedicated circuit board?
Thank you for this service,
AL
Hello Al,
The dedicated circuit cable does not need to be continuous, therefore a splice with an approved junction box may be installed so the circuit cable may be extended to the new location.
Be Safe,
Dave
