Morning all
Re: the electrical overload. I'm not sure of the finer details John. There is a huge building program going on at school with some 'blocks' closed off ready for refurb or demolition, many temporary buildings and a whole new buiding going up. I think that in disconnecting some areas and adding others, including supplies for the builders, they got the balance wrong between the three phase supplies. One was drawing 360A but the other two were something like 210A and 90A!! I don't think individual cabling came into it - just bad maths.
Given that they've already cut the phones four times and the water twice, I'm not really surprised.
