Answer / maulik shah

of course the direction of
current changes in negative
half cycle but the current flows
only when there is a close
circuit. So placing two fuses in
phase and neutral both wires
makes no technical difference
As there is only one close loop
in 1 phase circuit. Although we
have to check two fuses each
time it blows off.
