Wiring meter tails into switched fuse?

[tidyboiler]

I agree .... what confuses me is what you're calling upstream of the meter. ............ Be gentle - I'm just a thick old Geordie.

Shhhhhhhhhhh ............. divven't tell them pet.

Except..... (and I've said this before, so apologies for the parrot)...I've had guys from WPD say that they won't fit an iso downstream of the meter due to it technically falling under part P, and the DNO's aren't Part P registered!

They have a point.

The issue I'm having with this thread is the confusion / controversy over which way is upstream and which is downstream.

Me - being a simple Geordie - relates everything to the River Tyne. (It was a Big River ye knaa)

The River Tyne starts up a height in the hills and runs down to meet the North Sea at Tynemouth, so my simple Geordie logic tell me that the source of the river is UP stream and where it ends- up is DOWN stream.

To relate this to the electrickery, UP stream is the big building stuffed full of Babcock & Willcox boilers and Charlie Parsons steam turbines and DOWN stream is the 40 Watt bulb (sorry .. LAMP) hanging from the ceiling in me Granny's netty at the bottom of the back yard.

Have I understood this correctly?

I would say so, yes.

Using a fused 80A switch at origin to protrect SWA running to consumer unit on upstairs flat.

I've wired it so that the meter tails enter at the top of the double pole isolator i.e the tails running to the meter are fused rather than the supply to the consumer unit.

The meter installation guy has insisted that they be swappwed round saying that the meter tails must enter the switch and the SWA line is what should go into the fuse-holder. As it turns out not a problem but as far as I can see both solutions provide a double pole isolator between meter and consumer unit and overload protection so what's the deal?[/QUOTE

I cant believe what I am reading. The live supply should enter the switch & the SWA goes out from the fuse, where are these Electricians being trained, short Part P course.

Geordie...That should have said either;

Upstream of the head but before the meter, or

Downstream of the meter

I was probably thinking of the first, changed my mind as it was a mouthful and changed it without rereading it..

Yup, only the DNO is allowed to put an isolator between the head and a meter. The exception would be were the head feeds a DNO master meter and this then feeds a DB or split services to sub meters, then you could install an isolator between the master meter and the sub meters. It's all laid out in the Electricity Safety, Quality and Continuity Regulations 2002 and the ACOPs that the DNO's all have to abide by.

What about in a block of flats where the meter is in the flats upstairs and the DNO dont take any responsability for the risers including the ryfield in the basement and theres no meter before, just a 3 phase service head feeding the ryfield
