4. 100mA – to give a degree of protection against electric shock due to indirect contact situation

1.1 4p 100ma rccb Application:

For protection against risk of fire due to live to earth fault where fault current is insufficient to cause over-current protection device to operate.For protection against risk of shock from indirect contact with equipment suffering a live to earth fault.For protection against shock in potentially hazardous environment. As supplementary protection against shock from directly touching “live” parts.Note: an RCCB must not be used as the sole means of protection against touching live parts

  1.2 General rules for choosing RCCB:

a. Rated residual operating current10mA – to give a high degree of protection against shock in a hazardous environment situation that supplementaryprotection against shock from accidental direct contact is required.

30mA – to give a high degree of protection against shock from accidental direct contact is required when it must beable to trip within 40 milliseconds when a fault current of 150mA is detected.

100mA – to give a degree of protection against electric shock due to indirect contact situation

300mA – to give overall protection against risk of fire from electrical faults in wiring etc, only where sufficient current(typically less than 500mA)may cause incandescence of metal parts in suitable circumstances and in consideration thatinstalled over current devices would require far in excess of 300mA to operate.
