Brymen BM235 10A fuse silently destroyed by a switched off UPS leakage current..

-  "Regarding arc flash on regular outlets, I have had my share of very impressive events on both the typical 15A circuit and some higher ones (40, 80A)."

Do you mind sharing the details?   

I have shared it in one or two threads around here, but the short version is that, in at least two occasions, if I weren't using glasses I would have vapourized electrolyte and a blend of silicon/epoxy etched to the bottom of my eyes.

johnkenyon   Thank you for the idea.   

The UPS already had a covered hole with the exact diameter of a mains neon indicator... 
This is how it was meant to be made...

Nice, and the meter? Get a decent fuse  10x38mm 11A fuse ( Siba, Bussman) for the meter and consider next time using an small  extension cord with splitted cables ( earth, neutral and live) to connect a small load ( a 5V usb power cord)  and only connect in series the matched color / type r of cable when using current, also consider using a clamp / current AC transducer eg:

or even a clamp meter such the uni-t 210E.

The meter is waiting for the new fuse.
I already have both the UT210E and a splitted earth extension cord...

Good another thing to explore with the extension cable is leaks between earth-neutral or earth-live, putting these pairs in the clamps, without any load attached.

i follow previous post a recomendation for fuses, based on the  jpscalibrationservices  seller .

He lists shipping for Greece from 11 pounds to 14 pounds which is crazy expensive for little a fuse!
Obviously he makes money from shipping as well...

Another option maybe is tme:

https://www.tme.eu/en/katalog/#search=bussman+11A&s_field=accuracy&s_order=DESC


Look at the price difference

TME, thats where I bought the Bussmann fuse.   (I am also waiting for 2 ebay fakes..)
20 euros!  double the price of the SIBA fuse.

Am not sure though how the double price is justified...
