Question

Metallic conduits, boxes and enclosures set up on indoor walls in wet locations will be mounted with an air space of AT LEAST how far from or off the wall?

Answer 1

Metallic conduits, boxes, and enclosures set up on indoor walls in wet locations should be mounted with an air space of at least a few inches from the wall to provide insulation and protect against moisture.

Step-by-step explanation:

When metallic conduits, boxes, and enclosures are set up on indoor walls in wet locations, they should be mounted with an air space of at least a few inches from the wall. This air space acts as insulation, preventing heat loss or gain through convection and improving the safety and effectiveness of the electrical system. By maintaining an air space, the conduits, boxes, and enclosures are protected from moisture, which can cause damage to the electrical components.
