48.3.4 Before conducting a leakage current measurement
with the circuit in Figure 48.3, the appliance is to be
disconnected from the receptacle. It is to be
determined by closing S1, utilizing both positions of
S2, and observing the leakage currents at the
meter, that the stray leakage currents are
negligible.
N/A
48.4 120 volt cord-connected appliances N/A
48.4.1 The water spray test is to be conducted with the
switch in the "on" position. For a multispeed
appliance, the "on" position of the switch is to be
the low-speed setting.
N/A
48.4.2 The leakage current is to be measured using the
test methods and equipment described in 41.2 –
41.5, except that the circuit shown in Figure 48.3 is
to be used. The leakage current is to be measured
with switches S1 and S2 in all possible positions.
N/A
48.4.3 During exposure to the water spray described in
48.2.1, the leakage current is to be monitored
using both positions of S2. The leakage current
shall be no more than 2.5 milliamperes.
N/A
48.4.4 Immediately upon cessation of the water spray, the
appliance is to be turned off by opening switch S1
unless it was in the open position during the
exposure to the water. The leakage current shall
be no more than 2.5 milliamperes.
N/A
48.4.5 After the 30-minute monitoring period, the leakage
current is to be measured with switch S1 open and
using both positions of switch S2. The leakage
current shall be no more than 0.5 milliampere.
N/A
48.4.6 Immediately after each of the leakage current
measurements, a dielectric voltage withstand test
is to be conducted as described in 48.6.1.
N/A
48.5 Other than 120 volt cord connected appliances N/A
48.5.1 Immediately after the water spray test, the
insulation resistance measured between live parts
and interconnected dead metal parts of an
appliance shall be 50,000 ohms or more. After the
insulation resistance measurement, the appliance
shall comply with the dielectric voltage withstand
test described in 48.6.1.
N/A
48.6 All appliances N/A
