Just curious if anyone can tell me about power strips with GFCI. I am
wondering if in addition to using an isolation transformer, a power strip
with GFCI could provide an extra layer of protection against lethal shock.
Found this information on Wikipedia......
RCDs are designed to prevent electrocution by detecting the leakage current,
which can be far smaller (typically 5-30 milliamperes) than the currents
needed to operate conventional circuit breakers or fuses (several amperes).
RCDs are intended to operate within 25-40 milliseconds, before electric
shock can drive the heart into ventricular fibrillation, the most common
cause of death through electric shock.
In the United States, the National Electrical Code requires GFCI devices
intended to protect people to interrupt the circuit if the leakage current
exceeds a range of 4-6 mA of current (the trip setting is typically 5 mA)
within 25 ms. A GFCI device which protects equipment (not people) is allowed
to trip as high as 30 mA of current; this is known as an Equipment
Protective Device (EPD). In Europe, the commonly used RCDs have trip
currents of 10-300 mA.
