This electrical wiring project is about how to provide electrical power to a garden shed for a light and outlets.
Sub Panel How to Wire
Jason, from the information you have provided:
- In your question, you have described a sub panel which is a Single-phase, 3-wire, 125 Amp 240 VAC panel – which far exceeds what is needed for a few basic 120 volt outlets and a light in a small garden shed.
- You have not provided information about what size or type wiring has been installed to the shed, or the power source that you plan to install.
- You may consider installing a GFCI outlet as the main connection point for the power source, then wiring to the additional outlet, and light switch, and then the light.

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.
