Main switch rating
WebA nameplate is a metal plate attached to a device, such as a circuit breaker, that lists its technical specifications. See Figure 1. The circuit breaker ratings most commonly referred to are voltage, frequency, frame, continuous current, short-time current, short-circuit current, fuse, control voltage, and megavolt ampere (MVA) ratings. WebIn 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.
