Main Earthing Conductor

Former Community Member
Former Community Member
Hi All, 


Is it acceptable to install the earthing conductor from the service head cut out or is that the responsibility of the DNO? 


A friend of mine is on a PME supply but there is no earthing conductor present. The DNO came yesterday and snipped the seal and told him to get it sorted. 


Thanks in advance, 


Jake

    There are some designs of service head where a terminal is available to connect a PME earth, and all that is needed is a flat bladed driver, there is no seal on that part.

    (some common types shown here, see the variations....)

    ~If (only if) it is one of those and he has been told to proceed, then that is fine. However in his shoes I'd prefer a clear permission as an Email or text, not just the word of AN Other in a van.

    The usual thing to do is to add a foot or so of 16mm and then screw one of these marshalling terminals to a convenient surface and bring gas and water bonds etc to it.

    There are other designs of cut out that cannot be opened to get to the earth terminal without exposing live bits, that sort is always a DNO job, but you need to have the link wire to your own marshalling block dangling nearby ready and waiting if you want them to wire it in for you.

    Mike.
