Overview

Outdoor fixtures, outlets and their wiring should be in good shape – no worn, loose, or dangling pieces. They should also meet height and circuitry standards to protect them from mechanical damage.
Have a look at your outdoor wiring to make certain it is safe. Call a professional electrician if you spot any problems

The first rule is "look but don't touch." If you spot any problems, contact a professional electrician.

Steps

1. Check for loose or damaged plugs and fixtures:
   • Have fixtures that are loose or hanging from their wires repaired or replaced.
   • Examine electrical outlets for mechanical damage. Have worn or damaged outlets replaced with GFI outlets.
2. Check for damaged or loose wiring:
   • Check all the visible wiring on your home’s exterior for fraying at connections. Check the plastic sheathing that coats the wires for cracking, splitting, wear or rodent damage. Have it replaced immediately.
   • Loose wiring is prone to damage. Have it properly secured.
3. Check for improper wiring. Indoor wiring is not designed for damp locations and should not be used outside. If you find indoor wiring being used outside, have it replaced. If you are not sure, consult an electrician. Here are some things to look for:
   • Outdoor wiring has heavier casing to protect it from the elements.
   • Wiring rated for protected outdoor application has NMW printed on it.
   • Wiring rated for indoor use might have the letters NMD printed on it.
   • Most often, indoor wiring is white or red and outdoor wiring is black, brown or grey.
4. Check for unprotected wiring. Wiring less than seven feet above the ground must be armored cable (encased in a flexible metal jacket) or inside a plastic or metal conduit (pipe) to prevent mechanical damage. If you have unprotected wiring below that height, have it fixed or replaced.
