One more question on grounding.

[cyamaha2007]

Alright i have my light fixtures installed but not wired. They are contentious row mounted florescents. They are pushed tight to each other and a have a scab plate between them to tie them together. I will be using the fixtures body as a raceway/conduit to run my hot and neutral. So heres the question, do i need to run a ground to each fixture in a row? The way i see it is no, If i ground the first fixture in a row every one behind it will be grounded by the fixture body's almost like it was one long 56ft fixture? Am i wrong? Im using stranded wire so i would need to crimp ring/fork terminals to each ground wire connection.
You guys are a great help. Thanks Chuck

Did you use the supplied end cap in the slots shown in the last photo? If so, then connect the EGC at the point close to the point of entry of the supply conductors, & your good to go, no need to keep rebonding the EGC. I took it that you did use them by the text, but wanted to verify.

BTW, from the photos, the beginnings of a nice shop.

I would jumper the ground to every fixture. The painted steel of the fixture is not always a good conductor.

^^^Thank you, I did use the supplied scab plates. The pic is of a end fixture so no need for a scab plate. Thanks for the reply.

The paint is scraped away as the end caps are installed, no need for jumpers, what does slay me is when installers use both end caps then remove the KO's, then use a chase ****** & a locknut to join the fixtures, looks like hammered dog **** & wastes time and money.

Yes, you need a continuous ground. Say you removed one lamp fixture for servicing, that would break the ground (let's not get into the fact that removing one fixture in your configuration being impossible--it is theory that counts here.) Also as mentioned above, depending on the fixture's connecting to each other to provide a ground is probably not a great idea.

You still need to run a ground and bond each fixture, because event though the are attached, each and every one of them is a piece of equipment that requires bonding. If this were my shop I would definately do it..

Having installed a few of those here, I would ground each. The paint would get in teh way and they are not exactly square where they would mate. Caveat - he's screwed them to what looks like a metal ceiling, so they might all have a good conductive ground - but through the ceiling panel and not the fixture...?

 

[cyamaha2007]

I did put a screw through each scab plate on either side of the break. My meter shows continuity between each fixture. I may still jump the ground to each fixture.

It is cheap insurance to add the ground wire. It only takes a few minutes more. I wired my whole shop in conduit and still pulled a ground wire in every one. Good grounding is money well spent.
