maximum demand am i right

[markzsparks]

Hi everyone am i way off the mark in calculating my maximum demand i have 6 circuits
1x50 shower 10.5kw, 3x32 ring finals, 2x6 lights.ive calulated 100% for the shower =50
ive then calculated 40% on the ring finals=38.4 then 66% lights =7.9 totaling 96.3 ive
worked these out from osg table1b using section 9 but to be honest not sure whether im doing it
correctly any help

Lighting - 66% of total current demand for each circuit
Power - 100% of the first ring circuit + 40% of all other circuits
Cooker - 10A + 30% of remaing rated current + 5% if the CCU has a socket outlet
Shower - No diversity allowable


Hope this helps mate.

I can see where you are comming from, but the question is if the shower is included in the Standard Circuits. Since it is not a storage vessel, and not part of a comprehensive space heating installation I don't believe it is and therefore falls under section 5 of table 1B. Consequently section 9 of table 1B only applies to the ring circuits and you have to take 100% of the first circuit.
