Divvent fogit Sooth Shiels man, thas mair than one pier ye knaa

Aye .. aahh knaa man .. aah wez keepin' it simple fur aall the furriners we have on here man !!!

Wu divven't want te confuse them !!!

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.

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

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

if there is a private or adopted submains between the dno cut-out and the meters upstairs , then all bets are off and you can do what you like and fit isolation at any point after the main fuses.

Outspoken - what do you mean "upstream of the head but before the meter"? By definition anything upstream of the head must be before the meter! lol. Are you sure you're not confused. Sizewell is upstream, my kettle is downstream.

As Biff has said, in this situation all bets would be off, but usually there is a 3 phase check/Landlords meter from which all sub-mains would be fed..well thats how it used to be done, appreciate that things may be slightly different now as I have not done a block of flats for about 20 years!

If you have nothing constructive of funny to say, even at my expense, then there is no point sticking your toe in the water!

 

[terminator]

Ouch!
It was meant to be constructive for any new guys. It's not uncommon to confuse upstream and downstream. (even for seasoned guys) :49:

 

[Outspoken]

No worries terminator...I have one of these all to myself
