3 Phase / Single Meter - change to one communial meter, 4 sub meters, 4 flat supplies

[ianbrookes]

I'm doing the design work for a job. anyone done something like this before ?

ANY IDEAS GRATEFULLY RECIEVED



Supply is TP&N. It has a single Meter feeding a bunch of stuff and a few fuse boards (next to the meter).

The customer is converting the house into 4 flats each with it's own meter.

The new meters will be in a cupboard 10m distant from the incoming supply.

There is a picture of the supply attached.

I am thinking;

1 - rip all this old stuff out and leave the communal fuse board where it is
2 - connect the existing meter to a new TP&N distribution board
3 - run supply cable to each new meter (10m away)
4 - each meter will then connect to a switch fuse
5 - each switch fuse will service supply cable/tails to one fuse board (in each flat)

but potentially means lots of cable from the existing supply to the new cupboard


another option would be to;

1 - leave the communal fuse board where it is
2 - install a TP&N switch fuse next to the existing meter and run a TP circuit to the new cupboard
3 - split the TP&N in the cupboard via a TP&N distribution board (for isolation)
4 - feed each meter from the TP&N dist board
3 - run tails for each new flat supply from the new meters.

Fit a ryefield board after the cutout. From here, feed each meter with a lateral service cable. Obviously agree the arrangement with the DNO engineer first.
