Can anyone ID these mcb's for me?

Hi, looking at the wiring on the Ribtec I've just bought as the bulge pump won't run. I came across these in the JB. Can anyone ID them for me, or am I completely wrong and they're fuse holders???!

Many thanks!

Yep. they're fuse holders. Pull the rubber covers off. They'll be standard blade fuses.

Sorry, just looked again and saw the row of what looks like circuit breakers.

(box looks like it's been full of water!)

Sorry, my fault, not specific enough. It's the round ones with red 5 or 10 I meant...

They are circuit breakers.
5 Amp or 10 Amp being the current at which they should pop.
As LT pointed out you have some rust there so might be worth renewing the connector blocks.

Be warned! Once you start renewing...................

I WANT to rip it all out, but I'm SCARED to!

Seriously, the boat is in great shape and if the wiring were up to standard it would be a cracker...

Winter project methinks.

Can you guys advise best supplier for marine electrical supplies?

TIA!

I use either 12volt planet or Kojaycat. Personally I would only use marine grade tinned copper stranded cable & adhesive lined heat shrink crimps.

If, and IF I tackle it, it'll have to be done right. I'm good for that, but having fitted a few new consumer units I know what s PITA it'll be...
