Well firstly, there is no way a 16Amp socket should be protected by a 24 amp mcb. Well thinking, I am sure they don’t make a 24 amp mcb . So firstly ask them what breaker you are on ,maybe 25 type b or c. If so ask to have the socket changed for a 32 amp. Which can be used on a lower mcb size. Do they have any 32 sockets anywhere . On your socket post how many 16 amp sockets is there.

But just changing the socket type isn’t going to help with the AC units tripping. I think I need 2 32 Amp sockets feeding the 2 shore power sockets. Someone told me to create a Y cable to the 2 sockets on the boat and feed them from a docket in the post, again, I don’t feel that is right?
 
No don’t do a y cable if they are fed from , two phases there would be a bang and you would be putting 400 volts into your boat.

You're not being very precise with your language and your repeated use of "socket" to mean different things. With the above edit, that Y cable will work fine as regards voltage and you wont need to worry about phases and 400v. Whether you can get enough current from a single socket on the dock post depends on the dock supply.

A quick question on shorepower. My boat has 2 shorepower connections, each 32 amps is my understanding.

At my home berth I’ve been given a 16amp socket with a 24 amp breaker. The marine post can’t handle any more amperage without upgrading the cable.

When I run AC Heating, I can only run 2 of the units, out of 4 available without causing a p5 pwr error on the displays.

What’s the thoughts on what I need to get this working as per design?

I’m only connected to shorepower 1 socket on the boat.

It is very unlikely you will be able to run all 4 AC units from a 16Amp supply however you wire it up.
Yes you can make a Y connector from one AC source into two input sockets into the boat
But don't make a Y lead from 2 AC outlets on the marina posts into one input socket on the boat. Bad things will likely happen.

Well don’t want to deviate from is problem , but the regs s displayed, only one socket should supply a craft or house boat.

UK regs state all outlets on a pontoon must be on the same phase., so no bangs and no 400 volts.

Not that i'm suggesting making such a Y cable.

Yup, but I didn't say otherwise.

Indeed, given that hundreds of Fairlines/Princesses/others are built with two 230v inlets (bus A and bus B). it is 100% necessary to have a Y structure somewhere in the wiring if you're going to comply with the regs and feed the boat from a single dock socket.

So yes, the Y is intended to be on the boat. With one connection on the marina power post. I’m suspecting that will need to be at least 32 Amps. I’m going to check the amps on each ‘bus’ as per owners manual and I’ll revert back here soon.

I think they were suggesting using two plugs.

I got the post upgraded to 32 Amps, in fact the electrician said he upgraded to 42 on something. Even without splitting at the boat via a Y connector it seems to be much better. I'm going to load test this weekend with all the AC Units on etc, if it trips then I'll get the Y connector ordered and try that.

Well if one side trips , how will the y help
 
No more than 32amp should pass through a 32 socket only on inrush currents, also what size cable is your lead.

great that the marina upgraded your connection. You should be fine. If it trips after the upgrade, get an electrician.
