Big Clive's "Trashy" meter, unboxed ( Duratool D03047 multimeter )

Which is why I would curious if any UK based electricians here could indicate what kind of prospective fault current would be measured at a typical UK 13 A wall socket? (It would be a range, obviously, but typical/min/max would be interesting.)

Wikipedia says typical UK ring circuits have 30A fuses and 2.5mm2 cable.

Seems like it would be fairly common information and easy to find but my search was a bust. I did come across this site for the electrical workers. Mostly seems related to industrial environment.

Audio buffs are concerned with it.. The sound of a top of the line audio system would certainly be degraded if plugged into my lab's outlets.
Fungus:
All UK mains plugs are required to have BS1362 fuses in them, and the biggest fuse is 13A.

Really? Plenty of CAT III meters here, but I dont not have either:
mains impedance measuring tool (as to measure the earth and lines individually)
or
some significant and benign load (such as a resistive heater or load bank) to do a simpler line-neutral measurement
Sure that second item might be somewhat common, but the first is specialist, and I wouldn't call either route "basic". We know the ceiling to impedances here because Australian installations are required to maintain a maximum droop under their full load.
joeqsmith:
Really.
