probably an easy answer if you know it, unfortunately I don't (or just cant bloody remember)... but how do you work out cable sizes when using more than one conductor?
Basically, and I wont go into specifics, but there's been a lovely cock-up by the ground workers and instead of putting in a nice size duct for me, they've put in multiple small ducts, meaning I'm going to have to install multiple SWA's
Is it a simple case of the rating of a single cable (with normal correction factors applied) and multiple it to reach total loading requirement. Or what?
ie. if a 4mm SWA is capable of carrying 25amps over the distance, will 4x 4mms be capable of 100amps?
