3 phase supply but single phase boards question!

[devonsparky]

Hi...........my first post so please be gentle!! I am an approved electrician and am currently doing a fair bit of testing for the company. I am still learning the testing/inspect side of the trade so do have the odd question from time to time!!

So here goes, today I tested a community centre which had a 3 phase supply but the installation was off of 3 different single phase boards. (From meter blocks on a phase each)
Does the PFC have to be multiplied by 2 as its a 3 phase supply or as each circuit is off of a single phase board, does the PFC just stay as it is!!
A pretty easy one but the football was on and I was rushing!!!! ha ha

Cheers

The PFC would be for each board as you find it, the pfc's are probably going to be more or less the same (at each board) if the db's are in close proximity.

P.S. You should have 3 test certs 1 for each board
