why the 4 terminal are named as main, line, common, voltage (M, L, C, v) of a wattmeter?? why not..

Answer / deepika

The three terminals are M, L, C, V
M stands for main load, L for connecting load, C for common, V is for voltage
There are two coils - current coil is between M and L, potential coil is between C and V

Answer / magesh kumar.s

'M' it connect one is voltge phase and 'M' to 'C' are inter
connect.

'L' it is used to connect load (or) energy meter.

'C' it is a capactive device is a support device.

'V' it is a voltage to connect transformer neutral and also
connect energy meter.

so they are not its named A,B,C,D.
