I was giving connections of a tubelight in home with out switching off the mains..Suddenly sparks came when I was trying to remove the insulation of phase and neutral wires for tube light connection ...Power has gone..later we checked that fuse and replaced our fuse..But what is the actual cause of that spark... what s d reason for that
Warning: never work when the power is alive.... turn off the main power supply or atleast turn off the switch corrsponding to the tube light... then work... in your case the phase and neutral wires might have touched or come very close in humid environment....
