If there was something tapped off, that would show up when testing.
I've only got the time fault characteristic chart for mcbs to 60898, but I'm sure that it's not a million miles away from a bs 3871 and that shows that it would need about 11 amps to trip a 6 amp mcb in about 5 minutes.
That means a resistance of about 20 ohms.
