Phase rotation

geov
Hi all, long time not here, but as always, value the opinions of members.

EICR on a commercial. Incoming phase rotation correct at head, but all 8 sub mains in the MCCB panel have been incorrectly installed L3, L2, L1.

Been like this since the building was refurbished 10 years ago.

They do have some three phase equipment which is running happily ( tho’ I’ve not been able to switch off to see if the rotation fail  has been corrected at the local isolator).

I’m minded to code C3 - anyone disagree & if so why?

    I suppose if they have 3 phase kit, it needs noting so nobody tries to fix it and damages something, but it is pretty small beer, and quite common in some parts of the world (hence all those plugs where you can flick a switch and swap 2 phases over.)

    C3 or just a note and no action seems about right.
