YEDL Want a Load figure

[oharaf]

Called to a light industrial unit today.

Customer is splitting the unit into 2.

Currently has a 3 phase supply.

He wants YEDL to provide a seperate supply to the other unit to be, for metering purposes.

He has completed the paper work 'ticking' 3 phase.

They have returned it asking for a LOAD figure.

This is pretty impossible to give.

all I know at the moment is the unit requiring the new supply is only going to be used for plumbing storage a few sockets for power tools, lighting and the office.

However the customer agreed that it would be sensible to leave all options open.

The over-riding factor is that both units have roller shutters powered by 3 phase motors.

He/ we thought it would be best to put a figure of 55kVA based on the info given of

upto 20kVA for single phase and upto 60kVA 3 phase.

I would appreciate any imput on this.

The other unit is to become a garage with a ramp also requiring 3 phase supply, this is not a problem as the 3 phase supply is already there!!

20KVA = 87A
so a 100A each phase 3 phase supply should do you..

Thankyou oh 3 Phase King

Dug me out twice tonight much appreciated!!!

So If I tell him he should tell YEDL he wants 100A per phase it MIGHT satisfy them?!?!

Cheers

Central networks refer to a 100A x 3 Phase suppy as a 70kW supply.

They are probably still using 240v in their calcs as 70kw it works out just a shade over 100A per phase at 230v

Yes, Spark123, seems they live in the real world!
