Formula for Calculation Incomer Rating

Single Phase (Amps.) = Total Load (Watts) / 230 Volts *Cos ϕ
Three Phase (Amps.) = Total Load (Watts) / √3 * 230 Volts *Cos ϕ

* The above data is only for guidance and may vary from manufacturer to manufacturer. The proper load of appliance should be checked for current requirement & appropriate Wire & MCB size should be selected accordingly.

The human body's reaction to electric shock - Electrical shocks, passing through the human body, confuses its internal nervous system and it causes the body to react to the passage of current through it as follows:

CURRENT	REACTION
Below 1 Amp.	Generally not perceptible
1 mA	Faint Tingle
5 mA	Slight shock felt. Not painful but disturbing. Average individual can let go. Strong involuntary reactions can lead to other injuries
6 ~ 25 mA (Women)	Painful shocks. Loss of muscle control
9 ~ 30 mA (Men)	The freezing current or “let go” range. If extensor muscles are excited by shock, the person may be thrown away from the power source. Individuals cannot let go. Strong involuntary reactions can lead to other injuries
50 ~ 150 mA	Extreme pain, respiratory arrest, severe muscle reactions. Death is possible
1 ~ 4.3 Amps.	Rhythmic pumping action of the heart ceases. Muscular contraction and nerve damage occur; death is likely
10 Amps.	Cardiac arrest, severe burns, death is probable
