As I said, I have worked in electrical trades in the past. Employers had need for various test equipment that I used in industrial commercial and residential settings. Currently do not have the equipment to measure fault currents (safely or accurately) or even a mains current clamp....

Is the maths or reference to standards I present somehow questionable because of the lack of current equipment that I personally own? Is the personal equipment I own related to my knowledge of safety regulations or a desire to not see people encouraged to ignore them? No. Take your FUD and shove it.

It's fine when you question my statements and ask me to show data to back up my claims.  Guessing you were not expecting me to actually follow through.  Now that I have and the roles have changed you start whining and telling me to shove it.    :-DD :-DD :-DD :-DD

Quite the opposite, I'm happy there are some measured numbers for people to consider but typical figures or calculated examples would have been fine. All I was after was the prospective fault current as your prevailing local standards (of which I know almost nothing about) were likely to be different to the standards we have here.

Measurement categories from 61010 are international and to protect people from (almost) worst case conditions (including faults and transients). Simple rules with almost universal application. Many things could make specific installations/setups less dangerous than that but its then down to (learned) people applying that specifically and not trying to extrapolate out to other situations.

joeqsmith measuring a prospective fault current on a socket outlet larger than 1kA? Yep, sounds like it when the meter in question doesnt have the required specifications or ratings to safely withstand that much energy. This thread being about a meter that has a claimed CAT I, and joeqsmith saying it shouldn't be a problem for mains.

Or perhaps these gems from the 61010 standard:

--- Quote from: AS61010 ---for equipment marked with measurement category I, a warning shall be given not to use the equipment for measurements within measurement categories II, III and IV
--- End quote ---

--- Quote from: AS61010 ---Measurement category I is for measurements performed on circuits not directly connected to MAINS
