Guard wire have a supper conductivity & almost negligible
resistance , that why leakage current can easily flow through
it..

Answer / arvind

as guard wire has less resistance wire but some where we use g.i wire whose resistance is high but the correct answer for that should be that the current choose a path to ground which is less resistible it will go through that and our body is less conductive in comparison to the conductors

I have a relay contact rated at 220v dc which is supplied with a 24vdc from the panel,for it to trip the dampers(24vdc).What if the application of the relay changes so that it should work at its rated 220vdc then will it work at 24vdc supply given or any other consideration needs to be taken .....
