Electrical wire Based on the current and voltage rating of the meter and breaker, #4 size AWG copper wire is the highly suggested type and size of wire.

Why copper wire is used in meter bridge?

The value of resistivity of nichrome wire is 1.10×10−6Ωm, which when compared to copper wire whose resistivity value is 1.68×10−8Ωm , is around 100 times more. Thus, copper, due to its low resistance and high temperature coefficient of resistance, cannot be used in meter bridges.

You will need four-conductor copper wires to wire your breaker box. These cables run from your main switch to the meter and are known as hotwires. These are the same type of wires that carry electricity from its source to its designated destination.

Why thick wire is used in meter bridge?

The connections between the resistors are made of thick wires so as to increase the rate of cross-section. Therefore, the resistance of wires is almost negligible. b) Balance point is obtained in the middle of the meter bridge wire so as to increase the sensitivity of the meter bridge.
