PanelboardsGeneral SpecificationsBussing SequenceInteriors are designed to accommodatetop or bottom feed. Regardless ofwhich is specified, the uppermost poleis always on “A” phase; the secondpole down is always on “B” phase, andthe third pole down is always on ”C”phase (assuming 3Ø panel).As standard, branch breakers shall bemounted at the top of the panel with“spaces” at the bottom, regardless ofthe direction panel is fed.GeneralAll breakers have bolted connectionsexcept plug-in type. The panel designprovides bracing up to 200,000A IR ULshort circuit rating. Case-hardened, highperformance, thread rolling screws areused on branch bus.Circuit Breaker LightingPanel Type P1Circuit Breaker Lighting orDistribution Panel Types P2/P3Circuit Breaker DistributionPanel Type P4/P5Fusible Switch DistributionPanel Type P4/P5Panelboard RatingsDescription P1 P2 P3 P4 P5Max.
