tell 2 reasons for why only copper is used in domestic
wires& only alluminium in transmission lines ?
Answer Posted / suresh
the same for home &
in transmission we have to transmit long distance if we use
copper its(costly&weight)when compared to alum.& distance
b/w the pole is decrease
and due to capacitive sending end Volt SEV < REV if v use
alum some Wat it will reduce.( HV the current flow around
the cable not inside the wire y should v use costly
copper).in LV current flow inside the cable

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
