Currently converting a barn on our farm which is attatched to my parents house. I own the barn and in partnership with my dad. We will be looking to sort the electricity out soon and we're planning to connect onto my parents supply and install a meter. Is this possible or will we need a separate connection? Transformer is 300 metres away, currently run on poles. Have a friend who is a electrician and said 100 amp supply to my parents would be enough for our place as well, as long as we have a gas oven and hob and no power shower. Advice???
