Coastal and Floodplain Construction Inspector's Practice Exam

Where should lighting circuits and fixtures operating at 120 volts be located in Category II structures?

1. At the base of the structure

2. BFE + 1 ft or DFE, whichever is higher

3. Above the roof level

4. Only in protected areas

The correct answer is: BFE + 1 ft or DFE, whichever is higher

In Category II structures, which are defined by their risk of flooding and the potential impact of flood damage, it is essential to elevate electrical components to minimize the risk of water exposure. The correct location for lighting circuits and fixtures operating at 120 volts is specified as being at the Base Flood Elevation (BFE) plus 1 foot or the Design Flood Elevation (DFE), whichever is higher. This guideline helps ensure that the lighting remains operational during flood events, protecting the integrity of the electrical system. Elevating these components to this specified level is a best practice that minimizes the risk of electrical hazards, such as short circuits or fires caused by water intrusion. Location at the base of the structure poses significant risk since floodwaters can easily reach this level, leading to potential damage or malfunction of electrical fixtures. Placing fixtures above the roof level may not be practical for typical lighting applications and could lead to complications such as accessibility for maintenance. Lastly, restricting installations only to protected areas does not adequately address the risk of flooding and does not follow the established elevation guidelines necessary for safety in these structures.
