This is something I've been meaning to ask for sometime.

What do you guys put for 'Distribution reference, or distribution reference number' on the forms? Sometimes there is what looks like a specific number on the CU, but more often than not there is nothing to distinguish a particular CU.
 
PS... If someone could answer fairly quickly please as I'm watching 'The Evil Dead'..... alone.... in a remote, old house. :anguished:
 
I heard they made a remake ? Not that i'd be interested in that. Still weighing up if my kids are old enough yet to watch the original. I have so many horror films to show them.

As for the db thing, call it what you want. Once you put a label on it, it's named. Call it Malcolm, or Sandra.

Are you referring to DB reference?
Either leave it blank if there is only one, or call it #1.
If there is more than one, either give each a # or a description.
 
If they aren't already labelled then I would generally begin at DB1 and make my way from there.

Agreed. As an aside (more relevant in commercial) when a board is retired or replaced, unless the circuit arrangement of the replacement is an absolute 'like for like', it is good practice to retire the former DB number, as opposed to reusing that DB number. This is to avoid any confusion in documentation that may exist referring to a former board layout.
 
Lol. For a reason I can’t explain I always call it main when there is only one. Probably thinking main(s) or the main one. Dunno, never really thought about it until now. DB1 works though.
 
As I understand it there can only be one MET for an installation, this is the one that the earthing conductor connects to. Any other earth bar after this is an EMB (earth marshaling bar)
I agree. The word "Main" in Main Earthing Terminal should be evidence enough of this. Others would be, as you indicate, Earth Marshalling Terminals.
 
He did explain to me the difference between IP4X and IPXXD, which I always thought were just different ways of saying the same thing, also IP2X and IPXXB

If you look at the definitions they are quite different indeed. In fact IPXXB and IPXXD allow surprisingly large gaps.
