SHOCK HAZARD: As defined in American National Standard, C39.5, Safety
Requirements for Electrical & Electronic Measuring & Controlling Instrumen-
tation, a shock hazard shall be considered to exist at any part involving a
potential in excess of 30 volts RMS (sine wave) or 42.4 volts DC or peak and
where a leakage
current from that part to ground exceeds 0.5 milliampere,
when measured with an appropriate measuring instrument defined in Sec-
tion 11.6.1 of ANSI C39.5.
NOTE: The proper measuring instrument for the measurement of leakage
current consists essentially of a network of a 1500 ohm non-inductive resistor
shunted by a 0.15 microfarad capacitor connected between the terminals of
the measuring instrument. The leakage current is that portion of the current
that flows through the resistor. The Simpson Model 229-Series 2 AC Leak-
age Current Tester is designed around the ANSI C39.5 requirement for the
measurement of AC leakage current. See Figure 1 below.
