What characterizes mandatory rules of the code regarding actions that are required or prohibited?

Should or Should not
Must or Must not
May or May not
Could or Could not

The correct answer is: Must or Must not

The correct answer is "Must or Must not" because these terms denote mandatory compliance within the context of electrical codes. When a rule states that something "must" be done, it indicates a required action that must be followed without exception. Conversely, when the rule states that something "must not" be done, it clearly prohibits the action, ensuring safety and compliance with established standards. These definitive terms reflect the legal and regulatory framework governing electrical installations, where strict adherence is necessary to prevent hazards and ensure safety. In contrast, the other options—"Should or Should not," "May or May not," and "Could or Could not"—represent guidelines or suggestions rather than requirements. These terms imply a degree of discretion or optionality, which does not align with the binding nature of mandatory rules in the code. Thus, "Must or Must not" best encapsulates the essence of mandatory compliance in electrical regulations.
