when the PFR (POWER FACTOR REGULATOR)change a step to
zero,one of the RCCB will triped off,is it the changing step
of this PFR effect the RCCB?
Answer Posted / pillay
what is a RCCB doing inside a PFR. Any way if a rccb trips
than it means there is a earth leakage.otherwise the wiring at
the PFR is wrong especially the neutral connections or the
RCCB itself is faulty. Check all the wirings first and than
try substituting the RCCB itself
