Ground Wires for Outlets
Electrical Question: How should I ground an outlet to a box?
I am running MC cable (3/8-1/2″) into handy boxes in series around my garage wall. I have one cable entering bottom of handy box and one leaving the top of handy box. How do I ground the box and outlet? the conductors are stranded copper. Do I strip the insulation and wrap around the ground screw on box and use crimp clamps to bond wires and use the tail of one to bond outlet, or do i need to use ring terminals and take all grounds to box ground screw, or wire nut all grounds and use 2 pigtails , 1 to box and 1 to outlet?

Thanks for your Electrical Wiring Question Chris.
How to Ground Electrical Outlets
- As you have described, there are a few options for bonding the ground wire.
- This goal of this task is to ground the box and the outlet using a method that works with your wiring and box space situation.
- Pig tailing is my favorite way in most cases, and the ring tongue or fork spade crimp connectors work best when installing stranded wire, just be sure to use a good pair of crimp pliers.
Electrical Tip for Outlets in Metal Boxes
- Installing 1- 1/2 deep 4-square metal boxes and installing outlets into raised metal industrial covers is preferred because these junction boxes provide more cubic inch space.

3 Essential Electrical Tips
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
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.
