Guide to Repair Lost Power to a Shed
Electrical Question: I have lost power to my shed. I have underground cable that has been working for the past ten years.
- No plugs in the shed work, the light does not work either. It is not the case of plugs not working.
- I use my voltage tester on the main feed into the shed and I get a power reading inside the shed on the main feed power.
- The lines from the box inside the shed to the light and other plugs show that there is power, yet when I turn on the light nothing happens. I changed the bulb but that did not help.
- There are six plugs that do not work and I don’t know what to look for.
Thanks for your help!

How to Repair Lost Electrical Power to an Outdoor Shed
- With this question, I am assuming that there is a direct burial cable that supplies the power circuit to the shed.
- If there is a direct burial cable, then what you are describing sounds like the main underground power cable has lost the neutral.
- This may have happened if the cable was nicked when it was installed, and slowly it began to deteriorate until the connection was finally lost.
- To know for sure, voltage tests should be taken from the hot leg of the power to the neutral wire, not to the ground wire.
- If there is no reading then the neutral wire is the problem.
- The problem area can be detected using a cable detector or meter and then an approved direct burial repair splice may be installed to restore the connection.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!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, [amazon.com], I use for the detection of Standard 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.
