Question

The minimum conductor size for a ___ Amp service is a 4 AWG copper or 2 AWG aluminum.

A) 100 apms.
B) 200 amps.
C) 300 amps.
D) 400 amps.

Answer 1

A 4 AWG copper or 2 AWG aluminum wire is the minimum size for a 100 Amp electrical service.

Step-by-step explanation:

The minimum conductor size for a 100 Amp service is a 4 AWG copper or 2 AWG aluminum. When determining the appropriate wire size for electrical service applications, it is essential to consider both the current-carrying capacity and the material of the conductor. Copper and aluminum are widely used due to their good conductivity and ability to be drawn into wires, but they have different properties necessitating different gauge sizes for the same amperage service ratings.
