curent,or insulation is low class.

Answer / s.k. ghosh

Earth Fault means single line to ground fault or double
line to ground fault.Earth leakage means a equipent or

how to calculate current carrying capacity for cables?

Answer / m bilal akram

a line touch with ground is called earth fault due to this
current flow back to sours.earth leakage equipment work on
kerchief current law incoming current is equal to outgoing
current.when not equal UN balancing current flow due to this
current flux generate in sensing coil(CT)and then tripping
occur with CT output.
