I have carried out wiring for lighting in a shed in
Industrial area which contains Metal halide lamps & have
balanced in 3ph.Now when we put all the lines on in the
daytime the current taken at 3phases at MCB comes to be
equal i.e.28,29,28Amps respectively but in the night time
i.e between 7p.m.to 11p.m. at the same MCb the current is
52,59,62Amp, though I have fit 63A MCB it is tripping in
the above period.What may be the reason.?
Note: This industry is located in industrial area where
majority of steel ingot manufacturing plants are there.
Whether this may be due to harmonic? what should I do to
overcome above problem.pl suggest urgently.
