Class CTL panelboards incorporate physical features which, in  conjunction with the physical size, configuration, or other means
provided in Class CTL circuit breakers, are designed to prevent the installation of more over current protective poles than the number for which the device is designed and rated, per UL 67 and National Electrical Code (NEC) NFPA70.

When a panelboard is used as service entrance equipment, it must be located near the point of entrance of building supply conductors. In a main lugs only panel, the number of breakers or switches directly connected to the main bus must be limited to six. In a panel having a main breaker or main switch, the number of circuits are not limited except as may be provided under other panelboard requirements, i.e., lighting and appliance branch circuit panelboards. Also, panels must include a connector for bonding and grounding neutral conductor.

42-Circuit Rule: NEC Paragraph 408.14 defines a lighting and appliance branch circuit panelboard as one having more than 10 percent of its over current devices rated 30 amperes or less, for which neutral connectors are provided. NEC paragraph 480.35 states that not more than 42 over current devices (other than those provided in the mains) of a lighting and appliance branch-circuit panelboard shall be installed in any one cabinet. For the purpose of this publication, a two-pole circuit breaker shall be considered two over current devices; a three-pole circuit breaker shall be considered three over current devices. (NEC 480.34 and .35 do not apply to panelboards feeding and communication circuits. Panelboards for this application must be so marked.)
