8.4.2 The dielectric withstand test equipment shall employ a transformer of 500-VA or larger capacity and
have a variable output voltage that is essentially sinusoidal or continuous direct current. The applied
potential is to be increased from zero at a substantially uniform rate until the required test level is reached,
and is to be held at that level for 1 minute.
Exception: A 500-VA or larger capacity transformer is not required if the transformer is provided with a
voltmeter to measure directly the applied output potential.
