Circuit Metering

[LED Lighting]

Hi All

I have been asked to install a New DB to serve 40 offices, with the facility to meter each office individually.
I was thinking of installing a 18way TP&N DB, running 10mm to each office where a smaller SP CU is installed branching off to 3 circuits. Lights, Sockets and electric heater. A Din Rail Energy Monitor would be installed in this CU.

Whole install is in Dado and plastic trunking on the surface so RCD is in the office CU and not the 3P&N DB.


Any thoughts on this or any other way of doing it.

BS88 fuses or correctly set MCCBs are what you need, bs1361 has been replaced/merged into bs88 now

When did this happen.? That why theres no 1361 time charecteristics in regs now

theres 40 offices, so needs to be 16 or 18 way TP&N

Theres 28 offices (current) but will probably reduce to 20 in total being supplied off this board

I don't have my copy of the BYB to hand but I think this is technically called moving the goalposts.

Edit: link didn't work

might be better to use something like these for the distribution circuits.

Never seen these Lee, what sort of ocpd are they?

They are BS88 HRC fuse carriers. My browser wont let me post links for some reason but type hager LS201 in to google.
