Thing is, some older mains filters have a fairly high

run
Many pi-section line filters have capacitors connected between each
side of the mains and ground. If one were the slightest bit leaky,
it might warm up a bit and pass sufficient current to trip the (well,
we call it a Ground Fault Interrupter) RCD.
