Sub mains rooms.

[chcnorris29]

Hello,
Been doing some work today in a high rise where there are sub mains cupboards on each floor however the communal fuse boards and all main connections for flats (before meter, meter and fb in flats) has previously been relocated to 1 sub mains room off of an old unused office on the ground floor to prevent vandalism. (not the nicest area in the world to work, we where working there because they had stolen an earth conductor).

Anyway:

Was told by people I was working with that as an apprentice I legally can not be in the sub mains room.
Sound weird as how can you learn to work on the sub mains if this is the case.
is this correct?

Thanks

Yes this us what I meant sorry, gut a little confused I meant you can access customers sub mains but not DNO room. Used to big sites where try and DNO switch room in same room and usually bolted on to side of clients sub.

DNO switchroom’s are out of bound unless you are accompanied by a DNO representative.
Authorised persons of private networks where the intake and outgoing share the same board are allowed access unaccompanied.

Access to private switchroom’s is at the discretion of the site operator.

And that just about sum's it all up in a Nutshell!! lol!!

The rest is just making things up as they go along, or mistakenly quoting a company policy as an actual industry regulation!!!!

I’ve worked on several setups. On the bigger sites the 33/11KV transformers belonged to the company, the 33KV coming from a separate building. Access to them would be accompanied. We would only go in there to confirm a feeder had been earthed and our locks applied.
Smaller sites had the boards combined so we needed access. You couldn’t do anything with the DNO gear, if it’s possible to get a lock on something they would.
