Never mind fuses these replace re-wireable fuse holders!

How do you find the supply impedance without resorting to measuring the
short circuit current?

Measurement is the only way.

If you ask your supplier, they'll just say 16kA which is the maximum.

How close are you to your nearest transformer?

Mine's a fair way away and my PFC is about 2kA (measured by me).

Brain fart - it's 1.2kA

OTOH, I had more than 5kA at a flat that has a transformer outside.
