According to the Code, what type of box can be used with EMT?

The correct type of box that can be used with EMT (Electrical Metal Tubing) is indeed a metal box. Metal boxes are typically utilized with EMT systems because they can provide a secure and robust housing for electrical connections and junctions. They also help in enhancing grounding and bonding of the electrical system, which is crucial for safety and effective operation.

While options such as wood, plastic, and glass may have specific applications within electrical installations, they are not commonly used in conjunction with EMT. Metal boxes ensure that the installation maintains integrity and functionality while adhering to electrical codes and safety regulations. Additionally, metal boxes can withstand environmental stresses better than many other materials, making them a preferred choice for various electrical applications.
