Grounding LOR Boards

Dan:

I was looking at Don's setup and noticed that he did not use the Ground wire coming into his controller box. Is there a place on the LOR boards for an equipment Ground? If not, what good is having a GFCI upstream on the feeder circuits?

I am particularly interested since most enclosures now are plastic!

Grounding is not on a LOR board. You can ground the incloser if you have metal but, as long as you are not using a grounded light string you will be ok!

GFCI work with 2 wire as well as 3 wire (2 wire plus ground) applications.

You do not need a ground for them to work, which is why they are so important (ie life saving) when you are dealing with outside electrical elements exposed to moisture.

Like Greg said, GFCI's don't depend on having an equipment ground. In fact, the NEC (electrical code) specifically calls for GFCI's to be placed (ungrounded) in places where the equipment ground wire is not available (e.g. old homes with only 2-prong outlets).
