Which of the following best describes the usage of metal boxes with conduit?

The use of metal boxes in conjunction with metal conduit is a common practice in electrical installations. Metal boxes provide a secure and robust housing for electrical connections, protecting them from physical damage and environmental factors. When metal conduit is used, it not only offers a protective pathway for electrical conductors but also serves as a grounding means, enhancing the overall safety of the installation.

In environments where durability and protection are paramount, such as in commercial or industrial settings, utilizing metal boxes with metal conduit is beneficial. This combination helps to ensure compliance with electrical codes, which often require proper grounding and protection of electrical components.

Metal conduit can be advantageous for certain applications, such as indoors in dry environments or outdoors where weather impacts are minimized. The key takeaway here is that metal boxes are suitable for use with metal conduit, capitalizing on their collective strength and safety features in wiring installations.
