240 volt system into yacht

Please read the link before posting any more bad advice like your previous posting:


Even on a small boat you need to follow the regs!!!!!

I'll include my signature on this post.

I did read the link and stand by what I said, it's perfectly possible to have an installation completely in line with regs with no faulty parts and still electrocute someone in the water between boat and pontoon. I didn't make this up, it's specifically mentioned in the boat electrics book I have as a consideration when deciding how to do your installation.
I'm not sure why you're quoting me saying that about my installation either, I fully explained why I chose not to have a main isolator switch on my boat. It is not in line with the regs but the switch in question would serve no purpose on my boat and so I chose to leave it out. Had I fitted it, it would live on the opposite side of the bulkhead to the cable connection point and would actually be harder to use than unplugging the shore power. Since the purpose of the main isolator is not to break in an emergency but to isolate from the supply my solution makes perfect sense and causes no danger.

Having read some of the posts on these threads I am rapidly coming to the conclusion I must be Very careful before taking advice!!!

The important thing is to double check all advice before going ahead, not to choose the most plausible sounding post. These posts will give you sufficient information to find the correct information with very little effort but you should never just trust them. With electrics threads forumites often mention the regs - this gives you enough information to find the regs and read them. They are not particularly long so an easy read. Also often mentioned is stranded wire which gives you enough info to make sure you find out the right cable to use. Add all of this up and you have enough info to research the solution you need for your boat and decide whether it's within your abilities.

The marina are upgrading a lot of power to 32a at the moment so I have had quite a lot of on board low voltage AC job requests over the last 6 months or so, far in excess of the usual level and the standard of some installs, everything from no consumer unit at all, relying on the shore side protection to low voltage AC cables below bilge level to solid core conductors.... the list is endless. I have to work to BS EN ISO 13297:2012 Small craft - Electrical systems - Alternating current installations so have had to refuse to even touch some of it, it's scary.
