AC Resistance
In Simple words, Resistance in AC circuits is called
Impedance. Or
The Overall resistance (Resistance, Inductive reactance and
Capacitive reactance) in AC circuits is called Impedance (Z).
DC Resistance
We know that there is no concept of Inductive and Coactive
reactances in DC Circuits. i.e. capacitive and inductive
reactances in DC circuits zero because there is no
frequency in DC circuits, i.e. magnitude of DC current is
constant. Therefore, only the original resistance of wire
comes into play.

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.

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?
