Marinco shorepower socket

[jimmy_the_builder]

Hi Jimmy,
Many thanks for helping out here, I think I may have confused issues by giving duff info in my first post.

The Marinco socket as fitted is marked with 30A 125V and not 16A as first reported, but has no mention of 240v anywhere on it, the socket is wired directly to the distribution panels 32amp RCCD (marked 240v).
So the 32amp breaker at the distribution panel is rated higher than the boats shorepower connection socket.
Boat is a standard Targa 28, built for the UK market.

The shorepower cord and plug are normal Arctic grade, blue 3 pin 16Amp stuff, the breaker and socket marina side is 16Amp.
I know the 32amp plug/socket sizes and confirm their not that big.

Iv'e ordered the 50A 125/240v socket from EBY (kindly suggested by Swifty).
I Looked at a few Fairlines down at the Marina today and the one ordered is common to all of those looked at.

One final question though, is it worth swaping out the 32A main breaker for a 16amp seeing as we only use a 16amp shorepower lead that's plugged into a socket protected by a 16amp RCD shoreside?

Did you mean EBY, or coastal rides? Remember that the 32a inlet is physically larger than the 16a - so you'll need a new plug as well.

Ref the breaker - if you're upgrading the inlet, why do you need to downgrade the breaker?

Cheers
Jimmy

Hi jimmy et al. No hard feelings, the problem with the written word eh. Interesting correlation between power ratings on the sockets though. 30a @ 125v, that's pretty close to 16a @ 240v (220v) of about 3.8KVA for each, accurate enough for these calculations. Doh, said I wouldn't comment didn't I .
Glad a replacement socket has been found although I would suggest wisdom in Jimmy's words re sockets and breakers. I have a similar set up on my Princess. A 16a commando recessed commando socket fed from a 16A breaker and 30mA rcd shore power but the boat supply is covered by a 30mA 63a rcd with a separate 32A double pole breaker in the main switch panel. The supply is all fed through the ups which has a programmable limit of 16A anyway because I too was confused by the contradictory ratings on the various system components but it looks as if mine is no different to anyone elses! So if nothing else it has reassured me that my system is 'normal' even if confusing.

Now I'm getting confused,
Iv'e ordered the 50A socket from coastal Rides (not EBY,sorry Jimmy, well spoted) at £35+ vat & postage it worked out at £50, which aint too bad after some of the prices iv'e seen.

However Boatingdave has just answer a question I hadn't asked, the original marked at 30A 125v was adequate for the 16A 240v shorepower cable connected to it, it just didn't say 240v on it which is why I got confused as to it's suitability.

Looked at a targa 31 which had the same as Iv'e ordered from Coastal rides, 50a 125/240v, are you saying that the new socket will require a new 32A plug for the shorepower cable?

I guess I will have to see when it arrives, many thanks to all who have responded.

. . . . Today I fully investigated, removing the marinco input socket from the boat as the terminal pins looked green with corrosion, . . . . .

Notwithstanding the corrosion and amperage queries that you have, be very aware that this input socket comes in a variety of types.

I had this problem last August and ordered a Marinco (female) plug to fit into the Marinco receiving mounting in the boat.

It took three weeks from America and when I got back to the boat it was totally wrong as the third pin with the 'dog-leg' had the dog-leg outward going instead of inward going.

The other thing is that Marinco sell the parts either separately (outer yellow plastic cover and inner workings) or they are sold ready made up.

If you buy them as separate items, make sure that they fully fit correctly and that when the inner part is fitted inside the yellow plastic cover, that the locking bezel will be able to mate to your boat. Mine didn't and they guy in the shop told me "this is how they come". The inner electrical part protruded out of the yellow case about 1½ inches and no way could the locking ring mate onto my yacht. It would have allowed the weather to get into the electrics.

In the end, I went to Marine SuperStore, Port Solent and purchased the correct unit, 16-Amp ready made up (dog-leg inwards), for a cost of £78.99
