im a 3rd year apprentice and need some help on a few questions:
State the procedure and equipment required to perform each of the following tests
a) insulation resistance for alarm cables
b) continuity of alarm cables
c) Safe isolation of a 230Vac supply
for b) i was thinking multi-metre set on resistance shorting all the cores together at one end and testing between each one. and then checking them again un-shorted to make sure i dont have any shorts i shouldnt have.
and c) was thinking metre set on voltage
test the supply at my IAP for 230v remove the fuse from my 3a unswitched fused spur and put the fuse in my pocket. test at IAP again making sure the supply is dead.
any help would be greatly appreciated
