Outdoor Light Projectors & Earthing
Outdoor Light Projectors & Earthing
(OP)
Hello,
I would like to know if somebody installs outdoor light projectors on the boundaries of their building,do they need to be earthed?
If yes,can they be earthed with the armoring of the cable or do they need an earth conductor?
Thanks

RE: Outdoor Light Projectors & Earthing
Make sure the armor/ grounding conductor is suitably terminated to provide effective and continuous) path back to the source ground bus.
I doubt any different, but your local codes may have some say in this.

What I found seems to indicate that in the USA:
The armor of type AC cable IS listed for grounding.
The armor of type MC cable IS NOT listed for grounding.
The armor of type MCAP cable IS listed for grounding.
Check your cable type and your local codes.

Thanks for the clarification.
I found a fairly new configuration. It is basically MC with a bare aluminum conductor under and in contact with the armor.
It is called MC All Purpose, or MCAP
The most accurate answer to the original question may be;-
"It depends!"

ScottyUK I am sorry for not specifying,I live in the Middle East & the projects that we take here not only in my country but other Middle Eastern countries they don't care which code you are using as long as you are using one,I know UAE follows mostly the BS,but let's say the rest don't care and the question I asked was for one of those scenarios where no code is specified & being a fresh graduate more oriented in electrical communication I am having hard times finding myself in this area of the domain,if you notice around the forum I am asking too many rookie questions hopefully with time I will become up to the level & I am in need of your guidance & experience as much of anybody else on this forum,sorry again & Thank you all!!!
