Hi Folks, A lorry hit a wire going from the house to the garage a few months back when we had an extention done. Please see attached picture. I don't think the wire is damaged and the one that supports it was already down. Can anyone tell me what kind of electrical cable I should buy to replace it with and what junction boxes I should use on each side to connect the new wire up to the existing ones? It's a simple job I just want to make sure I have the right bits.
