C2 or c3

[wrighty]

Alright,

im currently testing a store and come across a situation I'm a little unsure on. I've got 3 4c SWAs feeding 3 different boards, no separate earths with any of them and no fly leads from banjos to the DB their feeding or supplied from, there relying on the trunking and chassis of the main panel to get their earth, zs fine etc, so would this be a c2 or a c3 in ur opinion

What are the ZDB readings like?

 

[wrighty]

0.11-0.15

 

[Pete999]

Do they comply with the types of OCPDs you have installed?

 

[wrighty]

Yeah,,

 

[Pete999]

Yeah,,

Man of few words I see

 

[wrighty]

No, but it was a yes or no question so I answered it,

 

[Pete999]

Difficult one I would say C2 No I'll edit that and say C3 improvement recommended

 

[Andy78]

I would say C3 as well, although I am not sure which reg would back me up on that.

If your ZDB readings are within the limits, by fitting a link from the banjo to the earthing bar should improve the readings, not got my 7671 handy so can't help with a reg noView attachment Best-Practice-Guide-2.pdf think Ive got the right one attached sorry wrong one, try looking at the best practice guide for EICRs on google cant seem to get my copy to attach
