I need information from some body that has done electrical work in abu dhabi. I need to know how they do panel (distribution board) schedules in Abu Dhabi. Especifically GFCI protection (RCD). It is for commercial/industrial project.

i undestand they use british code help anyone?
 
You need to consult the curent standards.

If its British standards then you need RCDs at least on any circuits feeding outdoor sockets, and anytime that the prospective short circuit current phase to ground of a circuit is too low to trip the overcurrent device in the required time, which I've forgotten what it is. And the scope may well have increased as there is a new version of the standard since I worked with it.

I say again: You need to consult the curent standards.
 
You will want to find out if they stay with current British codes or if they just used one cycle as a starting point for their own standards. The UK recently implemented the harmonized color code which changed all of their wire color coding. This is significant as it is usually a part of the panel schedule.

A typical schedule is based on a 3-pole slot and the color code for each phase on that slot. ATTACHED info is based on the old color code of Red/Yellow/Blue w/ Black grounded conductor the new harmonized color code is Brown/Black/Grey w/ Blue grounded conductor.

Hope this is helpful. though I think I may have misunderstood the question after a re-read....

Yes thank you. I have a sample of a panel schedule that shows a six slot 63A 100mA RCD rating in one colum and then the next colum is the actual breaker size (10,20 ,,,amps) and it has the color code you mentioned as the old standard. Do you know what this is about?

Design should be in accordance wit the British Wiring Regulations. You should purchase a copy of this document so you know what is expected.

I have a copy but the code does not explain how to do panel schedules
