Hi all,
I'm currently doing a load of landscape gardening and while I've got all the earth up I want to run an armoured SWA cable to an external building. Someone already put something in as a spur from main room ring mail in the house - not ideal and the wall switch for it gets hot under load so I want to run a cable from this all the way to the main fuseboard and have an electrician terminate it properly.
So I estimate the cable run from the external building to the fuseboard in the house will be 30 metres, allow for a HUGE margin for error. Assuming this, I want to be able to allow for 18Kw draw from this building (electric shower plus usual extras). Can someone confirm what I would need for a 240VAC, 18Kw draw over 30 metres? I've tried finding online calculators but not luck!
if it turns out to be a ridiculous gauge of cable (and so cost), I'll ditch the shower and allow for a 8Kw draw instead.
Also, I'm assuming I can just bury armoured cable in some plastic ducting, lay some 'electric cable hazard' tape above it and that's legit?
Thanks everyone for any and all help!
