Dear friends,
first it is common sense that in earthing you set more 100ma means when 100ma or more current is flow in nutral / earthing it may be trip. You aware that fatal current is 5 mA to 10 mA.
It is advisable to set 30 mA when in your home or industry you use 24 hours duty i.e continuous duty.
For higher capacity it i.e 100mA or more is apply where more current rated single apparatus is use. It is advisable to fit rccb with refrigerator, single phase water sump motor or pump and heater use in your house. In those house where small kids advisable to fit rccb.
