Can you recommend a good source for blade cartridge fuses

I have some fat cartridge fuses on the yacht. They have never blown, but of course one will do at an inconvenient time. I thought that I should keep a spare for each. However I am having trouble finding replacements. A Legrand supplier will only sell in packs of 3. I assume that there are equivalents and they do not have to be Legrand.

Does anyone have a good source for these???

Thanks

I inherited boxes of stuff like this from my predecessor and ended up scrapping most of it as couldn't warrant holding onto it. Nicest option is Blue Sea resettable circuit breakers - these will replace the old distro stuff you have there, although they're quite expensive.

Next best option is to fit MEGA holders and fuses, good quality ones from littelfuse for instance are reliable. You'll keep a few spares or a "kit" on board incase of any blackouts.

Otherwise I'm happy to hunt through the remaining piles of stuff and see if I can give you some extras, although not sure what ratings they'll be, if any.
 
Good idea to keep a spare or two on board. They are NH fuses, very widely used in industrial applications. Armed with that knowledge, you can easily find them online, e.g on eBay.

The brand does not matter, the rating does however. You'll need the right amps of course, the right size (so they physically fit) and they come in different speeds. Here's a handy set of tables for all of that: https://www.swe-check.com.au/editorials/nh_fuses.php

From your photos, yours seem to be all fast acting gG ones, except one slow aM, probably the windlass.

Thanks. Since you know about these, can I ask why the metal lugs for pulling them aren't live? They look as if they are touching the blades. I do have an insulated fuse puller so it is a theoretical question.

I will go and research on eBay now.....

They are live most of the time - I think the design just doesn't specify it explicitly.
 
I would look at changing the carriers for a fuse type readily available as you will eventually run out of any spares you may have at a time you don’t want too

Good idea. I wonder how easy this is. An RCD with flick swtich would be ideal. Off to do more googling

You don't want an RCD, you want circuit breakers or fuses.

I'd want to double check the rating that you have are correct, you have a lot of high current fuses there.

200a and 400a breakers are not available in many affordable styles. The BlueSea 187 series goes to 200a, these are ridiculously priced at about £120 each, but if you do a search for "Bussman 187 series" you will find them much cheaper (the BlueSea ones are actually Cooper Bussman). Options for the 400a one will be limited.

I think the suggestion in post #2 to use Megafuses makes good sense. ASAP carry good stocks.
