diversity 66% of current demand for lighting

[Niblok]

hi guys got my self confused with diversity using conservatory as on example 6amp mcb

ok lighting 66% of total current demand. I have two lights in my conservatory 100 watts each 200watts total = 0.83 amps so 66% of that is = 0.54 amps is this right

or is it 66% of the 6 amp breaker

cheers

so then apply the 66% rule to a circuit that would supply power to kitchen,hallway,lounge and living room

You can't apply diversity to two lights in a room/conservatory, when they're on they're 100% on, but you can apply it to a number of rooms because the lights will not normally be on at the same time.

On what grounds do you base that statement? If a room is in-use the lights in it are likely to be on and it's not that unusual for all rooms on a floor to be in-use. So IMO applying diversity within a normal lighting circuit is crazy.

You apply diversity to the whole circuit that is protected by the mcb, but as stated normally is not needed for your standard house.
Normally it's okay to have 12 lamps at 100watts each, running off one circuit that is protected by a 6 amp MCB.

hehe. You are lighting one room with 200 watts of light. I'm lighting my whole house with 216 watts, and that includes outside. [/smug]

A head torch each for the whole family? Good idea that...

Nope. completely abandoned filament lamps. Moved in here over a month ago and used less than 100 units so far.
