Answer / vinoth

Human body can resist up to 30mA only...

Answer / vikram veer singh

the typical values for current are given below :-

BODILY EFFECT DIRECT CURRENT (DC) 60 Hz AC 10 kHz AC
------------------------------------------------------------
Slight sensation Men = 1.0 mA 0.4 mA 7 mA
felt at hand(s) Women = 0.6 mA 0.3 mA 5 mA
------------------------------------------------------------
Threshold of Men = 5.2 mA 1.1 mA 12 mA
perception Women = 3.5 mA 0.7 mA 8 mA
------------------------------------------------------------
Painful, but Men = 62 mA 9 mA 55 mA
voluntary muscle Women = 41 mA 6 mA 37 mA
control maintained
------------------------------------------------------------
Painful, unable Men = 76 mA 16 mA 75 mA
to let go of wires Women = 51 mA 10.5 mA 50 mA
------------------------------------------------------------
Severe pain, Men = 90 mA 23 mA 94 mA
difficulty Women = 60 mA 15 mA 63 mA
breathing
------------------------------------------------------------
Possible heart Men = 500 mA 100 mA
fibrillation Women = 500 mA 100 mA
after 3 seconds
------------------------------------------------------------
since the resistance of human body is about 1 mega ohm.
so calculate the voltage by ohm's law..

we have 3 phase 4 wire supply 230/415 V.AC and our distribution is single phase or we have all single phase 220 v,ac operated appliances. and noted the current with help of clamp meter Red to N = 20 Amps. Yellow to N = 45Amps and Blue to N = 30 Amps ( total is 95 Amps ) what will be neutral current on the main .
