2. Clamp the cable clip to accessible conductive sections of the chassis and
the enclosure.
Note
Ensure that bare metal is reached and that both jaws of the clip are in
contact with the chassis. Do not use metal labels or incidental
conductive hardware for this test.

Patient Lead Leakage Current
Patient Lead Leakage Current (I
P
) (source current) would flow through
individual patient leads and all of the patient leads connected together, if the
patient were to come into contact with earth ground. This test was originally
required only for devices incorporating intra-cardiac electrodes or conductive
