Looking through our periodic certificate that was completed by a 3rd party, I've got a few queries that hopefully someone on here can clarify.
We've got a Schneider Prisma switchboard (S3/MSP 3.1) fed from 11kV/400V Transformer.
- What is meant by MW for cpc size of 2/TP and 13/TP?
- Is there any reason why Max Permitted Zs is N/A?

My gut feeling is MW is short for metal work as in the metal enclosures the gear is in. As for the lack of max Zs, there isn't a table for it for 60947-2 MCCBs in BS 7671, so maybe they didn't have access to the required information and so N/A'd it.

But why not ask the third party, save any ambiguity or guesswork?

Thank you for the reply, I've asked them a few queries on the certificates and haven't came back with any clear answers, so thought I would ask on here
 
The certificate looks like it has been done by Amtech software if you don't disable the N/A it will fill all unpopulated boxes N/A
