75.1 The leakage current of a cord-connected unit shall be no more than 0.75 milliamperes when tested
in accordance with Clauses 75.8 – 75.10.
75.2 Cord-connected equipment that complies with both of the Items (a) and (b) below may be permitted
to have a leakage current from simultaneously accessible parts to the grounded supply conductor higher
than specified in Clause 75.1, but in no case shall the leakage current be greater than 3.5 milliamperes.
a) The product requires EMI suppression filtering for compliance with FCC regulations.
b) The product is equipped with a grounding-type supply cord and plug.
75.3 Components are considered to be in compliance with Clause 75 if they have already been evaluated
to and comply with other UL or CSA standards that contain a leakage current test.
75.4 Leakage current refers to all currents, including capacitively-coupled currents, which can be
conveyed between exposed conductive surfaces of a unit and ground or other exposed conductive
surfaces.
75.5 All exposed conductive surfaces shall be tested for leakage currents. The leakage currents from
these surfaces shall be measured to the grounded supply conductor individually as well as collectively and
from one surface to another where simultaneously accessible. Parts are considered to be exposed
surfaces unless guarded by an enclosure providing protection in accordance with Clause 5. Surfaces are
considered to be simultaneously accessible when they can be readily contacted by one or both hands of
a person at the same time. These measurements do not apply to terminals operating at voltages which
are considered to be low-voltage.
