Mandatory rules of the code are characterized by which terms?

The correct characterization of mandatory rules within the code is defined by the terms "Shall" or "Shall not." These terms indicate a requirement that must be followed in accordance with the building and electrical codes. When a code states that something "shall" be done, it signifies an obligation or a standard practice that is not optional but rather a necessity for compliance with safety and regulatory standards.

This terminology is utilized within legal and regulatory frameworks to unambiguously stipulate what is required, ensuring clarity in enforcement and adherence. "Shall" coupled with "shall not" denotes actions that must be taken or explicitly avoided, thus providing clear directives for compliance.

In contrast, terms like "must" or "must not" can occasionally appear in other contexts but are not the legal terminology used in the code itself. The wording "can" or "cannot" implies permission or prohibition, which does not necessarily reflect the mandatory nature of the code's requirements. Lastly, "should" or "should not" is typically used to suggest recommendations or best practices rather than enforceable rules, indicating that while these may be advisable actions, they are not binding regulations that must be followed.
