Electrical Wiring For Outdoor Post Lights
Electrical Question: I just replaced the wiring to an outdoor lamp post with a plug in the base.
- It was wired with indoor 12/3 and no GFCI. The power feed comes from a junction box in the basement which supplies the other 2 outdoor plugs around the house.
- There is a line to a switch at the front door upstairs which controls the outdoor lamp.
- The only alteration I made was to add a GFCI plug where the cable exits the house. Downstream to this is the lamp post and plug.
- Now, if I turn the lamp on, the GFCI trips. The lamp and plug share a neutral line. Is this the problem?
I would appreciate your advice.

- Checking the Wiring
I would suggest that you check all your connections and make sure the GFI is mounted properly.
- Connections to the GFI
The wiring of the GFI should have both the power and the neutral wired through the GFI outlet.
- Post Light Wiring
The wiring to the post light should be direct burial cable or wire in conduit.
