Hi all,
Just a quick one, I've been asked to price a EICR / PIR on some shared offices, its just the landlords testing so the general test to each "sub owned DB" plus the landlords communal lighting and small power.
I've been told I can't power down to one unit as the company has Servers and It gear. I know I can let this off with a limitation but can I put a Limitation on the Ze test for the building?
I don't think there will be any faults and all the sub boards and mains were upgraded 5 years ago
 
After you spend all day phoning i will guarantee the answer given by the person will be the maximum Ze permitted depending on your earthing characteristics.
 
Limitation for Ze. Zdb at your board, and see what you get, there is more than a good chance it will be well below 0.35/0.8, if so then no problems. If it is getting close to those values, then good old fashioned maths comes into play to work out your Ze.

Cheers.............Howard
