HOLT Electricians Complete Practice Exam 2025

Question: 1 / 400

What is the maximum distance within which conduits must be supported to be considered adequately supported in enclosures not over 100 cubic inches?

12 inches

18 inches

The correct answer is based on the National Electrical Code (NEC) standards, which provide specific guidelines on supporting conduits. For conduit systems installed in enclosures that are not over 100 cubic inches in volume, the maximum distance that they can be left unsupported is 18 inches. This requirement is in place to ensure that the conduits are secure and stable, reducing the risk of damage, and maintaining proper performance of the electrical systems.

While the other distances available in the choices may seem plausible, they exceed the maximum allowable support distance stipulated by the NEC for smaller enclosures. By adhering to the 18-inch rule, electricians can ensure compliance with safety codes, prevent physical strain on the conduit, and facilitate easier maintenance and inspection of the electrical installation.
