2 amp blade fuses?

Do they exist, or is the lowest rating 3 amp? I have to admit that I haven't looked that hard but neither my local suppliers of halford do 2 amp versions.

Some of the electrical stuff I'm fitting to my rib (notably the fish finder and bilge pump i think) require (according to instructions) 2 amp fuses. Could I get away with using 3 amp ones, or is that stupid?!

Thanks.

Tim

Quite rare to find them below 3amp but they do exist.

thanks for the replies guys.

In the hope that I won't have top buy some and pay postage (tight!), will my 3 amps be ok? If they are so rare, what does everyone else use?! I can't imagine my bilge pump (attwood) or fishfinder (garmin 160 blue or something) are all that unusual?

Have also tried Lucas and maplin and neither do them as low as 2amp! I already have some 3 amp ones so if I could use those, that would be a bonus.

Tim at least you are protecing the circuit, better than some I've seen (wired to the battery direct with croc clips!) You could always put an in line fuse holder in for your fishfinder if you are worried. They take the glass fuses (30mm) much more choice in sizes for low down ratings.
hope this helps

PS. My electronics are protected by a standard blade fuse, 3 amp. No probs in 6 years.

Excellent, thanks jizm.

as it happens, my fish finder has an inline 2 amp fuse built in. My dad was going to whip that out and use it else where but I think we'll leave it in. I would be surprised if my bilge pump gets frazzled on anything below 3 amps.

Bilge pump is an electric motor, which often takes quite a bit of current at startup. See if the manufacturer has a lock up current draw spec, and fuse for just over that.

The fuse is not to protect the item, but is supposed to keep the wiring from melting the insulation in case of a short.

but I do love the smell of burning insulation in the morning!

As my old man once said to me, 'wiring contains smoke, when you let the smoke out that's the end of it!'
