I am in the process of landscaping the garden, with an intent at completion of having a small log cabin.
I'd like this to have electric and data connection to the house.
Cable run will be approximately 17 metres and I am assuming S.W.A. buried would be the simplest method with a reaosnable level of protection.
Intent would be if this could be spurred from the existing ground floor ring of the house, which is RCD protected at main CU, would 2.5MM cable be sufficinet? My logic being that any attempt to laod with greater than 16A would trip the breaker for that circuit in the main CU before any cable current capacity over the suggeted run would be a concern.
Not looking to connect anything up, I just want to verify & purchase the correct size of cable so I can get it laid in before any more of the garden work proceeds. I'll have someone in to complete work at each end once things are further along.
Happy to buy 4mm cable as the difference is only a few quid - though also don't want to over engineer if there is truly no point.
