Warning About Splicing Electrical Cables and Circuit Sizes
I am working on a re-model project in my garage where I will enclose and insulate a room from the rest of the garage.
- I have a question about codes for splicing cables. Is this a really bad idea?
- I’m thinking of running a 10/2 NM cable to an electrical box, and then splicing 3, 20amp (12/2) cables from it for the little room which will pull some big electricity (music equipment).
- I think I know the answer: it would potentially pull 60amps through a 30amp cable.
- If so, does this mean if I want 20amp receptacles, I must use separate #12 cables?
I hope this question makes sense, and I really appreciate your time. Thanks a bunch!
This electrical question came from: Paul, a Homeowner from Flagstaff, AZ
Additional Comments: U all rock!
Thanks for your electrical question Paul.
Splicing Electrical Cables
- There is nothing wrong with splicing wires as long as the junction box is accessible and you are not mixing wire sizes.
- You may not splice a #10 wire with a #12. The circuit size must be determined up front, and for your garage outlets you may want a 20 amp circuit which a 12/2 NM Romex could be installed.
- I can tell by your questions that you really don’t understand electrical circuit design, and I’m suspecting that your project is being done without a permit.
- Both of these deficiencies spell trouble so I would advise you to slow down and make sure the remodel project is done correctly and according to code, otherwise your creating a fire hazard and we sure don’t want that, besides, you want a safe place to make lots of great music right?
- Well wiring is kind-of like music, you need to know where to put the right guitar strings otherwise the music will be wrong.

Electrical Junction Boxes for Home Wiring
Understanding electrical junction boxes and what they are used for. Home electrical wiring is the process of installing electrical wire to a location that will serve electrical devices or an appliance. One very important component is the box where the wire will be installed. The type and size of the home wiring electrical boxes will depend upon the circuit size, application and its location.

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.
