A long branch-circuit homerun is upsized with larger conductors to reduce voltage drop. What is the best statement about the breaker serving that circuit?

Correct Answer

D) The overcurrent device still must be selected to protect the circuit and connected equipment, not just because the conductor was upsized

Larger conductors may be used to reduce voltage drop, but overcurrent protection is still selected for the circuit and connected equipment. Upsizing conductors does not automatically justify a larger breaker, and it never eliminates the need for circuit protection.

Answer Options
A
The breaker should automatically be increased to match the larger conductor
B
The breaker can be omitted because larger conductors are safer
C
The breaker should be doubled whenever voltage drop is a concern
D
The overcurrent device still must be selected to protect the circuit and connected equipment, not just because the conductor was upsized

Why This Is the Correct Answer

Larger conductors may be used to reduce voltage drop, but overcurrent protection is still selected for the circuit and connected equipment. Upsizing conductors does not automatically justify a larger breaker, and it never eliminates the need for circuit protection.
