Hi Ralph:
Some say 0th fault to mean it is expected to fail, therefore you fault it,
before applying a single-fault.
Never heard of this process. And never used this process. And have never seen
it in a safety standard.
If bonding impedance test passes, then the circuit is
with our equipment.

How do you demonstrate the dielectric strength
between mains and user accessible circuits when
the accessible circuits are referenced to chassis?
Disconnect the ground, and connect the low end of

Gentlemen,

accessible circuits when the accessible circuits are referenced to chassis?

and it breaks down
Are you testing just line/neutral. To ground?

For the purposes of this discussion, there are two

Can anyone help resolve my confusion over the issue of equipment insulation

might get damaged by such tests.
More specifically, there are various safety standards that require (say) a
