shore power socket/plug

Well old vic said it was to provide double pole over current protection for the whole boat. New vic thinks differently so I guess just do what you feel :)

It would but its not a requirement of ISO 13297 except that
the need or otherwise for a double pole circuit breaker ( not an RCBO) is covered in 7.2.1 and 7.2.2

You were the first the mention an RCBO in the previous thread

TestMonkey insisted that the RCD should be replaced with a "twin pole circuit breaker" then quoted the definition in 3.19 of such an item as the reason!
His suggestion would leave you without an RCD!

You have fitted a garage consumer unit which, like those sold for shorepower intallations, has a DP RCD and SP mcbs for the individual circuits.

ISO 13297 requires that you have a DP mcb in the incoming supply. You do not have that.

Can you clarify these points please Vic? I'm now more confused than ever. I thought the outcome of the previous thread was that the RCBO was to replace the RCD since it offered overcurrent protection, RCD and a main switch in a single unit. Adding a dual pole MCB may achieve similar but would then require a larger CU and therefore be more expensive?
I'm not trying to argue, I'm now genuinely confused.

My interpretation of Iso 13297 is that a garage CU with a DP RCD on the inlet and SP MCBS for each circuit satisfies the the basic requirements ( at least for a polarised system )

However there is a requirement for a trip-free circuit breaker to be fitted in the incoming supply between the inlet connector and the CU but I think, after reading the iso many times, this may not be necessary if the CU is within 0.5m (??) of the inlet connector or if the wiring is enclosed ...Section 7.2 covers this.

There's no objection to replacing the RCD with a double pole RCBO as far as I can see but it does not improve the personal safety aspects of the existing RCD and the individual mcbs give all the necessary overload protection.

You posted a link in the previous thread to a 2 pole RCBO but rated at 40 amps
I assume thats the current at which it trips on overload if so with a 6 amp mcb and a 16 amp mcb on the circuits it never will. Any advantage of it as a DP circuit breaker is therefore lost.
I have not found one rated at less than 40 amps.
 
Thanks Vic, that's much clearer. Can you explain what a "trip free circuit breaker" is? I read the definition in the ISO doc but the first half sounds like what I'd call a switch and the second half sounds like an RCD. If this refers to a switch I think I'm happy with just unplugging and ignoring the ISO on my 20 footer :)

Its a circuit breaker which trips on overcurrent but which cannot be prevented from tripping by holding the reset button in .

At least that is what I understand

You wont need to bother with it if your CU is within 0.5m cable run of the inlet connector or if the cables are enclosed in some protective covering such as trunking or conduit.
But if the distance exceeds 3m .... read the ISO again!

look for the code LANDGL on this webpage:
http://www.philippi-online.de/index.php5?url=produkte.php5&m1id=2&sprache=en&kat1_nr=4&kat2_nr=3

I've been using these for a few years now as the connector on the boat's side and they are excellent. Small form factor, robust and several mounting options. These connectors accept loads up to 16 Amps @ 230 Volt.

yummy scrummy, thanks, loads of stuff there and loads of info. everything, in fact that ive been thinking about. german i believe.
so, where do you get this gear and the all important how much? if you could give me a retailer or something id be grateful. thanks

yep thanks, no use to me but may be of great benefit to some of the globetrotting live-aboards.

Why don't you send them a mail. The fact that their websites is in English make me believe they are more then happy to find you a way to order their stuff.
The prices AFAIK are not bargain base, but also not sky high. I've seen the quality of their stuff on another yacht that most of the electrics from them and it's really nice stuff, much nicer than most other stuff in that area

Cheers,

Arno
