Answer Posted / virendra joshi
Universaly W(power) = V X I , mean for a constant power if
current increase Voltage decrese & if viltage increase
current Decrese. In LT voltage is less ( 415 ) so current
is high & fuse is bigger in size, simonteniously in HT volt
is more then current is less hence size of the fuse wire
will be lesse in terms of cross section.
