Question

A separately derived transformer system has a size #1 AWG copper secondary wires. The smallest size copper grounding electrode wire will be

1. #10 AWG
2. #8 AWG
3. #6 AWG
4. #4 AWG

Answer 1

The smallest size copper grounding electrode wire for a separately derived transformer system with #1 AWG copper secondary wires is #8 AWG.

Step-by-step explanation:

The smallest size copper grounding electrode wire for a separately derived transformer system with #1 AWG copper secondary wires would be #8 AWG.

The American Wire Gauge (AWG) system is commonly used to measure the diameter of wires, where a higher gauge number indicates a smaller diameter. In this system, #8 AWG corresponds to a larger diameter than #10 AWG, #6 AWG, and #4 AWG, making it the smallest size copper grounding electrode wire for this system.
