Question

how measure capacity of conductor

Answer 1

Current carrying capacity is defined as the amperage a conductor can carry before melting either the conductor or the insulation. Heat, caused by an electrical current flowing through a conductor, will determine the amount of current a wire will handle. Theoretically, the amount of current that can be passed through a single bare copper conductor wire can be increased until the heat generated reaches the melting temperature of copper. There are many factors which will limit the amount of current that can be passed through a wire.

Answer 2

Answer:

1. The formula for calculating current carrying capacity is:

2. I = permissible current rating.

3. ∆Φ = Conductor temperature rise in (K)

4. R= Alternating current resistance per unit length of the conductor at maximum operating temperature (Ω/m)
