Safe Body Current, Let Go Current

Let Go Current
the let go current is the maximum safe current a person can tolerate and still released the grip of a energise object. the safe let go current is shown in below table.

Based on Safe let go voltage and current, the average wet body resistance for male and female and child is determined as

1130 ohm for male

1700 ohms for female and

2266 ohm for the child.
