Good morning all.
I have a question regarding diversity calc.
So, for example, I have a office unit that has three floors.
There is a main DB feeding the block, each floor has a submain DB feeding three single dbs.
For ease I will make all the DBs the same.
So, the single dbs supply:
3 x 16A Power circuits,
2 x 32A Shower circuits feeding a 7KW shower on each,
1 x 16A Water Heater feeding a 3 KW heater,
1 x 6A Lighting circuit feeding 6 x 20W lights.
So, for diversity I have
Power - (100% x 16) + (50% x (16 + 16) = 32A
Water Heaters - (100% x 30.4) + (100% x 30.4) + (25% x 13.04) = 64.06
Lighting - (90% x 0.52) = 0.46
Which give a total diverse loading of 96.52 A (100A supply).
Which gives a 300A supply to each submit DB and a 900A supply to the main DB
Is this correct?
Now, line 9 of table A2 gives a diversity of final circuits.
How would, if I should, apply this.
Thank you in advance.
Richard.
