The overcurrent protective devices used in panelboards are only LVPCBs or fuses/switches.

Explanation:
Overcurrent protection in panelboards is about devices that interrupt current when it becomes unsafe. The common protective options are circuit breakers and fuses, and many panelboards are designed to accept either type or a combination (for example, fuse-switch configurations or plug-in/bolt-on breakers). A switch alone does not provide overcurrent protection unless it is paired with a protective element like a fuse or breaker. Because panelboards can be configured with different protective devices or combinations, limiting them to only LVPCBs or fuses/switches isn’t accurate.
