600 Amp Panelboards with Main Breaker

The 80% rule, per NEC guidelines, states that a panelboard should not be loaded beyond 80% of its rated capacity for continuous loads — those lasting 3 hours or more. For a 600 Amp panelboard, this means continuous load should not exceed 480 Amps. This rule protects the panel from overheating and ensures safe, reliable long-term operation in commercial and industrial environments.
