Hook up help please.

NO, it's like saying that a 13 inch tyre will NOT fit onto a 15 inch wheel, they have different profiles, if you go to a wholesaler you will see the difference

You can use any MCB of the correct electrical specification in a consumer unit. The necessary physical dimensions are all standardised - they all fit a DIN rail, they all have exact modular widths, and the projecting parts all fit through the slot in the consumer unit cover. The only problems you will encounter are with paperwork - the warranties and installation guarantees.

If there's a number of MCBs, they may be connected by a section of copper bar (bus bar) rather than a length of wire. In that case you may have to replace a bit of the bus bar with wire. But that happens mostly in domestic consumer units, with lots of MCBs, rather than in a MH with only a couple.

3 pin sockets should be on a 16 amp MCB, not a 6amp.
In any case it sounds like the MCB has failed.

Pappajohn you can run a 3 pin socket on ANY size breaker up to and including 32amps, (if it’s protecting a ring final circuit), it’s what you are using on the end of the 13amp plug that you plug into it that’s important. The OP, like the rest of us on EHU’s will have a maximum available SUPPLY of 16amps, that 16amps needs to supply all sorts of things and other circuits in the MoHo, microwaves, hair driers, air fryers, laptops, Mifi, etc etc. 16amps is approximately (depending on input voltage) 3,680 watts/3.68KW at 230volts 3.5KW at 220volts (mainland Europe) or 3.8KW at 240volts (most of the UK). So that’s the TOTAL that the MoHo’s mains electrical system can supply.
OP please check that you don’t have more that 6amps/1.38KW plugged into your “faulty” circuit. Technically an MCB will disconnect the supply at 1.2 times its nominal value (this is called fusing factor), but you’ll be working it pretty hard just before it pops! So a 6amp MCB SHOULD be able to withstand 7.2amps/1.66KW before it disconnects. Manufacturing tolerances, age, previous “at the limit” usage etc will adversely affect the fusing factor, the age, usage etc MAY actually “kill” the MCB in the end. An MCB isn’t really all that sophisticated, see this short YouTube video.

Pappajohn, i hope i didn’t sound too condescending in the post above! Please accept my sincere apologies if it came across that way.

Cheers!

Wow the video was very informative never realised there was so much inside.

Just a rather overdue update to my problem. After some testing with a multimeter and process of elimination I've hopefully fixed the problem. I've replaed the circuit breaker and all seems okay at the moment. Thanks again for all the help and advice.

Glad you got it sorted, also glad that you’ve posted how you fixed it rather than leaving us hanging on for the remedy, like most people do! Thanks!

Cheers!
