Typical earth leakage
*
for 200 - 230 V supply
<5
mA
for 380 - 460 V supply
<10
mA
*
Typical earth leakage values were measured at steady-state conditions.
Note that higher leakage currents may occur:
i) under transient conditions such as power on or pump acceleration or
ii) with abnormal supply configurations such as a missing or earthed phase or unbalanced supply voltages.
