For a house with all-electric appliances and a size of approximately 2300 sq ft, what is the minimum size for the ground conductor?

• A. No. 6
• B. No. 8
• C. No. 10
• D. No. 12

Answer: (B)

The minimum size for the ground conductor in a residential setting can be determined by considering the service entrance and the overall electrical load of the building. For a house with all-electric appliances, it is vital to ensure that the grounding system is sufficiently robust to handle potential fault currents safely. Grounding conductors must be sized according to the National Electrical Code (NEC) requirements, which take into account the size of the service conductors and the type of system being used. For residential properties, the ground conductor is typically sized based on the largest branch circuit conductors. In this case, for a house with all-electric appliances, a No. 8 AWG copper grounding conductor is usually recommended as a minimum size. This is mainly because a house of approximately 2300 sq ft could easily have significant electrical loads that necessitate a larger ground conductor to ensure safety and compliance with electrical codes. Opting for a No. 6 would be more than necessary for typical residential loads unless there are specific factors requiring it; while No. 10 or No. 12 would be insufficient for a property of this size with all-electric appliances, potentially compromising safety and code compliance. Thus, the selection of No. 8 is appropriate and in alignment with established guidelines
