shock always depends on the voltage. never on the current.
for e.g. i have worked on machines where 4.5 kA of current
is passed through copper rings, but nothing much happens
when i touch them, the simple reason is that voltage is arnd
2-3 Volts. hence shock is always caused by voltage and never
by current.

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
