I'm in the process of replacing my old lamp poles and lights outside with new ones. I have noticed that the previous ones were installed with UF wire buried directly underground. Since moving into my house I've always thought it was weird that the UF wire terminates at the house by connecting it to a typical male plug. This is then plugged into my outdoor GFCI outlet which is on a timer switch in my house.
The problem comes about when hooking up my new lights - I see the UF cable that runs between the two lights is your typical 14-2 with a copper ground. However the UF cable that runs from the first light to the house is also 14-2 UF, but doesn't have a copper ground, instead it has something that looks like a string running through it.
So is it acceptable to not hook up ground to these lights since it is connected to a GFCI outlet?
