Cable Calculations - Diversity Applied

Apostolos
Good morning everyone.

This is a theoritical question that I have however come across....really a lot when inserting my loads in Amtech!!!!!

I have a DB which feeds lighting and small power in a reception area in a hotel.

The DB has various lighting circuits and various small power circuits (sockets, door access controllers, heaters, automatic doors etc etc etc)

As I understand there is one type of diversity that is common sense and is the "concurrency factor" which is applied to the DB as a whole.

I am more interested however in additional diversities for the individual circuits.

My question is this.

I have a room where the lights are all on or all off through presence detection. I anticipate that within a typical day the lights will be on 6 hours. That is 25% of the day. Does this mean that I sould insert for this specific circuit an individual diversity factor of 0.25?

Do I interpret this correctly?

    It is all guesswork. The hotel may let out a room all day and evening for business meetings etc. The lights may be on for hours. At busy times like Christmas the hotel may be full to capacity and everything used to excess. I suggest that you get your employer to book you in for a luxury weekend break at the employer's expense so that you can get a feel for the environment and take scientific readings.
