Hi guys, I have been asked to fit a ring main in a utility room currently being built with a outside socket and a lighting circuit with 4 led lamps and a outdoor light, this much I am comfortable with.
My issue is with the max demand,
The current consumer unit is loaded to the max with 212amp of mcb's
With a 60amp cut out fuse
So if I do the math 212a -40a x0.4 +40a
Gives me a maximum diversity of 108.8amp
So I'm already nearly twice my max demand already before I've started adding my circuits.
It's a 2 bed small bungalow, this seems hugely over rated, I would like to get my 1st NIC assessment done on this so i want to cover all bases.
So any ideas would be gratefully received, my thoughts would include
1. Request DNO to upgrade to 100amp cut out which would still not meet the criteria,
2. Test and possible down grade any overrated mcb's, there is five circuits for sockets????
3. Full load test
4. Could I apply diversity to each circuit independently ?
Here is the C.U and cut out
