Hi all
Can anyone please ask me some basic electric questions:
1) an over sized fuse is dangerous as it could cause damage to appliance(s) and fire?
2) an under sized fuse will not allow sufficient current through and will blow and appliance etc not work?
3) what are volt free contacts ie in a programmer/thermostat?
4) an oversized wire ie 2.5mm used on a lighting circuit is safe, but an undersized wire ie 1.5mm used on a ring main circuit is dangerous, as could overheat and cause fire
5) using a pull-cord switch that has 45 amps 230 volts on it is ok/safe to use on a circuit which uses say 30 amps 230 volts?
if anyone can quickly answer these I would be very thankful.
