content: Any ideas where I could buy these fuses in the UK? Or does anyone have a few they'd be willing to part with for a reasonable amount please?The one that's blown is in the low voltage side of a car battery charger, but is rated 250V on the cap.Farnell list them as US stock, so charge £16 for delivery. RS & Rapid don't carry them at all and google suggests ebay from china, which is longer than I really want to waitThanks.

content: Hi richlooks like they only wanted to save money and time not using a proper Automotive fuse for that purpose.The fuse you are showing is damn cheap and easy to assemble (Automatically?)I would try soldering a widely available Automotive Fuse to the Board, but for safety reasons and fire protection it could be also a bad idea

content: Thanks for the suggestion. It already has a user-replaceable automotive fuse in series with the positive output lead though. Unfortunately, the user couldn't find a 20A in their workshop so they substituted a 30Awhich is why the 15A axial blew (it's in series with the transformer secondary). There's enough electronics in it with low-side MOSFETS that it wouldn't have cost much more to add in an overcorrect sense to protect against abusive users

content: So add these:http://uk.rs-online.com/web/p/fuse-holder-accessories/0379274/They are supposed to only be rated up to 8A, but the odds of them carrying more are fairly good.

content: Nice find Ian, thanks. I'd discarded conventional fuse holders as there isn't enough height clearance. Those caps will allow me to get this back into service quickly and I can swap them out later if they don't like the higher current long term.Andreas, 32mm might work (need to measure board space first). Not sure why I filtered by only 20mm in my searchesMany thanks everybody for all the help. I'm now sorted to get parts ordered this evening for delivery tomorrow
