Guys,
I really don't want to start a problem here, but have a question... I recently acquired a 40L National Luna (I am in Africa mind, so please don't go mental cause it is not Waeco/Engel!) I am having a real problem getting decent fuses. Is there a difference betwwen say a vehicular fuse that runs on 12v DC and the same amperage fuse (or circuit breaker) that is made for household voltage. May seem stupid, but there you go! Oh, and before you ask the wiring is really heavy and there are no cigar type connectors in sight . Oh and if anyone is interested the fridge seems bl**dy
well made.
Cheers,
Gil

The current rating of a fuse is the same (for practical purposes) irrespective of the voltage of the circuit it is operating in. However the voltage rating is not - so it is OK to use a 240V fuse in a 12V circuit but a 12V fuse must NEVER be used in a 240V circuit.

PS. It's not a stupid question it's actually a very good one.

a lot of folks wouldnt know that, and put their life or someones elses at risk
12v cable/wire/fuses/switches (anything made for low voltages) doesnt require as good as insulation as 240v stuff requires

It is actually a good idea to use a household cartridge type fuse for high or constant drain 12v accessories as they usually have a large contact area on each end of the fuse and large contact area where they pug into the holder meaning that there is little chance of voltage drop.
Codan and Barrett both supply a large 240v cartridge type fuse and holder with their HF radios for just that reason.
I also use one for the frig and the compressor.

The exception to this is that some household 240Volt fuse holders & wire are not made for the vibration or waterproofing required in a car & wont last very long.

Many thanks for the replies - big problem solved! Will now get some big household type fuses as teeny blade fuses were my problem: dozens of 'em but no decent holders. The National Luna seems be be a pretty
well made piece of kit. Cheers guys,
Gil
