Ok, I'm doing canble calculations as revision for my forthcoming exam, I've lost pretty much all of my notes due to my ex binning them by accident, anyhow please help if you can with the following
3 x 400watt SON/ I High Pressure Sodium Lmps mounted on 5m concrete columns each fitted with a SP & N fused cut out in the column base.
My problem is and it might be 'cause I'm not thinking straight but what is a
SP & N fused cut out?
and is there any calcs/ factors I should take into account for street lighting? for doing cable calculations. This isn't for an assignment this is purely revision and I had the note I lost the notes, and I could do with some help. Thanks in advance
