Schneider Electric 17th edition quiz

[333rocky333]

In metallic construction with regards to the depth of cable, what are RCD's required for?

a. Lighting only.

b. Sockets only.

c. RCD required for everything irrespective of depth.

d. RCD's are not required. [/color]

That to me is confusing. Anyone else agree?

At first glance I thought depth , as in buried cable, then I thought of metallic construction meaning the cable as in pyro and swa .
Was the answer D then.

I said D too. I thought what it was getting at was that if you have earthed metallic covering, you don't need RCD's.

jock- OOI, how did you interpret the question?

hi as rf said in a metal stud wall
