Grounding Continuity; Rating; General - Century UL 1086 Manual

50
46.8 If the output of the test equipment transformer is 500 volt-amperes or larger, the test potential may
be indicated:
a) By a voltmeter in the primary circuit or in a tertiary-winding circuit,
b) By a selector switch marked to indicate the test potential, or
c) For equipment having a single test-potential output, by a marking in a readily visible location
to indicate the test potential.
When marking is used without an indicating voltmeter, the equipment shall include a positive means, such
as an indicator lamp, to indicate that the manually reset switch has been reset following a dielectric
breakdown.
46.9 Test equipment, other than that described in 46.6 – 46.8 may be used if found to accomplish the
intended factory control.
46.10 During the test, the primary switch is to be in the on position, both sides of the primary circuit of the
appliance are to be connected together and to one terminal of the test equipment, and the second
test-equipment terminal is to be connected to the accessible dead metal.
Exception No. 1: An appliance – resistive, high-impedance winding, and the like – having circuitry not
subject to excessive secondary-voltage build-up in case of electrical breakdown during the test may be
tested with a single-pole primary switch, if used, in the off position, or with only one side of the primary
circuit connected to the test equipment when the primary switch is in the on position, or when a primary
switch is not used.
Exception No. 2: The primary switch is not required to be in the on position if the testing means applies
full test potential between primary wiring and dead metal parts with the switch not in the on position.

47 Grounding Continuity

47.1 Each appliance that has a power-supply cord having a grounding conductor shall be tested, as a
routine production-line test, to determine that continuity exists between the grounding blade of the
attachment plug and the accessible dead metal parts of the appliance that are likely to become energized.
47.2 Only a single test need be conducted if the accessible metal selected is conductively connected to
all other accessible metal.
47.3 Any indicating device – an ohmmeter, a battery-and-buzzer combination, or the like – may be used
to determine compliance with the grounding continuity requirement in 47.1.

RATING

48 General

48.1 An appliance shall be rated in volts, and in frequency expressed in one of the following terms: hertz,
Hz, cycles-per-second, cps, cycles/second, or c/s.
48.2 An appliance shall be rated in amperes.
Exception: It may be rated in watts or kilowatts if the overall full-load power factor is 0.80 or more.
