high resistance and low melting point material must be used
as fuse because, a fuse (from the Latin "fusus" meaning to
melt) is a type of "sacrificial over-current" protection
device. Its essential component is a metal wire or strip
that melts when too much current flows, which interrupts the
circuit in which it is connected.
So as high current/ over-current flows through the fuse due
to high resistance high (I^2*R)power loss will take place
thus generating heat in the wire and the wire will melt
quickly as its melting point is low
Material used in fuse wire
Fuse wire is a thin wire made of different types of alloys
of chromium, aluminum, iron, nickel etc. The fuse wire
alloys are:
* Aluchrom alloy
* Cronifer alloy

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
