I agree. I bought a small motorsailer and had it delivered to Milford Haven. On first connecting it to the mains it blew a big locked fuse box nearby. I had to get an electrician from the yard to reset the breaker that fed the whole yard. He told me that this also fed the leading lights into the port, which were also now out!Ref "whole marina electrics shut down " and assertions that it is unlikely to happen.
It might not be common, but i've certainly seen it happen. Faults that cause an RCD to trip can have slightly random results, i've seen them trip something that shuts down a whole section of big marinas, could easily shut down an entire small one, whilst the RCD on the boat and on the pontoon connection have not tripped.
I'd suggest this particular issue is best left to someone qualified.
Investigation found that the previous owner had disconnected and removed mains sockets and simply twisted the bare wires together
