how do you work out maxium demand

[philipbbop]

can you show me how to work out maxium demand on a lighting circuit with ten lights on the circuit please

The way I used to do it was 100w per lampholder add them all up and divide by the supply voltage to give the amps,that was when we had lightbulbs on pendants before all these fancy fittings came out so 10x100 =1000 divided by 240(supply volts)=4.16a

then its 66% of this therefore maximum demand is 2.75A

table A2 on page 111 of the on site guide.

in the on site guide it says it 66% of total current demand how do you work it out by that

Work out your total load in amps by the formula given above then multiply that answer by 66/100

To be brutally honest this is pretty basic maths mate and if you struggle with percentages you're going to have a fairly major problem

Aye ..... that's the benefit of having a good edukayshun innit !!

More likely he's gone to bed for a rest.
