Volt drop again

NWDS · Feb 25, 2009

Evening fellas, am I right in thinking that when you have worked out the volt drop ( mV*A*M/1000 ) if this is greater than the values given in the OSG ( pg 124 ) then you would have to recalculate untill you could meet the values ??????????????.

recalculate using larger csa cable?

Thanks Apache, that is what I meant to post, I would need to increase my CSA to meet the OSG values.

Or reduce the length of the circuit

i can just imagine that... large factory unit wanting new lights....

'well we dont want to use a larger sized cable to overcome volt drop, so we will make the circuit length shorter. but you will need torches if you need to use that side of the building.'
