ICC Residential Electrical Inspectors Practice Exam

What is the correct approach to determining whether an attic space needs lighting?

1. Evaluate the space based on local codes

2. Ensure it is used for storage

3. Install lights regardless of use

4. Use occupancy sensors to automate lighting

The correct answer is: Ensure it is used for storage

The correct approach to determining whether an attic space needs lighting is primarily based on its use, specifically if it is utilized for storage. When spaces are designated for storage, adequate lighting is essential to ensure safety and facilitate easy access to items stored within the area. This is particularly important in attics where storage conditions can involve navigating around beams, insulation, and other objects that may be present. When evaluating whether to install lighting, understanding the intended function of the attic becomes critical. If the space is not used for storage or is purely a ventilation area, then the need for lighting may not be as pressing. Therefore, the use of the attic dictates the requirements for lighting installation and safety measures. In contrast, if the space is only occasionally accessed for maintenance or is intended to be left unfinished, other options like local codes or universal installation may not be as relevant. Additionally, while occupancy sensors may enhance energy efficiency in spaces with regular human activity, the primary consideration for lighting needs starts with the actual use of the attic space.
