NEC Commercial Electrical Practice Test

No part of a cord connected pendant fixture shall be installed in a zone over and within how many feet horizontally from the top of the bathtub rim?

1. 2 feet

2. 3 feet

3. 4 feet

4. 5 feet

The correct answer is: 3 feet

The correct answer indicates that no part of a cord connected pendant fixture should be installed within 3 feet horizontally from the top of the bathtub rim. This regulation is in place to ensure safety in wet locations, particularly in bathrooms where water exposure is likely. The intent is to minimize the risk of electric shock or equipment failure that could occur if the fixture were too close to the water source. In areas with high humidity or direct exposure to water, such as bathrooms, specific guidelines are set forth in the NEC (National Electrical Code) to protect both users and electrical systems. Fixtures designed for wet or damp locations typically have different requirements, and care must be taken to avoid installation in areas where they could be inadvertently splashed or where caregivers or users might be at risk of electrocution. This 3-foot requirement provides a buffer zone, helping to ensure that electrical cords and fixtures remain out of reach of any potential contact with water, thereby enhancing the overall safety of electrical installations in residential and commercial settings.
