ELECTRICAL SERVICE INSTALLATION FOR BUILDINGS

[Variac200]

Hi,

I would like to know some few things;

1. How are final circuits referenced/ labelled? eg. Board/breaker1/breaker2.....
And is there a laid out procedure for this?
2. What would be the best order of circuit protection; is it Main breaker/MCB/RCCB ?

Thanks, great minds.

Are you on the customer side, or the contractor?

What is your boss' preference or HIS requirement?

I am on the contractor side. I have seen some people mix it up and I want to know if there are Literature or some sort of guidelines to that effect.

My boss has not really given his preferences; let's just say he relies on my information and decision and I also look up to great minds.
Thanks
