    KVA new build development

    Thanks ProDave, I did say 13KVA they came back with 5.5KVA I said that I still don’t think that is enough. Eventually they came back with 10KVA felt like I was haggling with them. I was just wanting to confirm I wasn’t over exaggerating.

    It’s the calculation part I’m not confident with. I would think a 35mm 4 core would be fine. If you can help me out with the calculation when you have time that would be great. 👍👍

    To be honest I don’t know the Ze it is in a duct under ground with 5 other SWA  Ambient temp 30 😵 10mm sounds like he is penny pinching!
