ICC Residential Electrical Inspectors Practice Exam

What is the maximum load that should be provided for each receptacle on a circuit?

1. 180 VA

2. 120 VA

3. 1500 VA

4. 300 VA

The correct answer is: 1500 VA

The maximum load that should be provided for each receptacle on a circuit is defined as 180 VA. This figure is based on the National Electrical Code (NEC), which sets guidelines for load calculations in residential settings. It’s important to consider the nature of the devices connected to the receptacles and their potential maximum consumption. While the maximum load can vary based on the specific application and receptacle type, a value of 180 VA is reflective of the expected continuous loading for general-use outlets. This provides a sufficient safety margin to prevent tripping circuit breakers or causing overheating during typical use. Understanding this load calculation is crucial for ensuring the electrical system's safety and reliability, particularly in residential installations where multiple devices may be plugged into a single circuit. Additionally, it is important for inspectors to verify that the load calculations adhere to these standards during home inspections, ensuring compliance with NEC requirements and protecting against potential electrical hazards.
