Fused switch colour codes

[colind3782]

Getting around to sorting out various electrical issues on the boat. The switch panel has ten fused switches but they don't have any rating marked on them, just different coloured dots in red, blue and green. Does anyone know what rating the dot colours signify? For some reason the photo won't upload

I may misunderstand but pull the fuses out - the rating should be marked on each fuse

They're not pull out fuses but fused switches. I wish I could upload the photo!

Took some serious resizing!

I think you mean "circuit breakers" don't know any coding.

IF they follow blade fuse colours ;
Red =10A, blue=15A, green=30A

Latest standard for fuse colours and "resettable fuses" as follows.

6 amp Mossy Grn ral6005
8 amp Honey ral1005
10amp Red ral 3020
15 amp Blue ral 5012
20 amp Yellow ral 1018
25 amp Pearl White ral 1013
30 amp Light Grn ral 6018

I really can't check out much from your picture. It appears that you have mainly 10 amp and 15 amp fuses.
I have little to get a size reference from but if the cables have been matched to the fuse sizes then you would expect red marked fuse to have a cable size of 0.5 to1.5mm csa.
A blue marked fuse to have 1.5mm to 2.5mm csa .

I don't think you have any 20amp resettable fuses as they are normally wired with heavier cables 3.0 to 6mm csa. And none of yours look to be that size.

It might help if you can identify the circuits to each fuse.

Usually on most boat panels a very light fuse( less 6 amp) is provided for compass or instrument illumination.
Can I detect a possible 6 amp fuse second from the bottom right of your picture?

Sorry can't help anymore.
