Electrical Safety for Small craft On-Board Guide

grahamro

I've just purchased this guide.
I'm a little miffed that there doesn't seem to be any mention of a TT earthing system for shore supplies.
I quote " For a large percentage of UK small craft that have a permanent berth, especially those in marina locations, the majority of such berths will be serviced by a TN-S 230v AC single-phase shore supply."
Any marina or boatyard shore connection I've seen has always been on a TT system.
Explain away..

    Did you know 9 out of 10 cats prefer Whiskas or 80% of dentists recommend......

    As part of my job, I assist in gathering information for court. Such a statement would be straight back from the barrister with a big red circle and  question marks following one word.....Source??

    Pirate wiring clearly, the rest of us have a 'shore' supply. 

    But joking aside, I'd  agree - rather like another doc we are discussing on another thread it seems that stuff is sometimes pushed out without enough critical review. Actually very few DNOs in England will provide TN-S so unless it is your own transformer, or the supply dates back to  the swinging '60s, then it is either TT or TNC-s here.
