AND - Power and distribution panelboards shall be of the voltage and amperage shown, 3 phase, 4 wire, 50,000 amps AIC minimum, dead front, circuit breaker type, with main circuit breaker or main lugs only as shown, copper bus, fully rated neutral and ground bars, NEMA Type 1 enclosure and surface trim. Provide circuit breakers as shown. Eaton Pow-R-Line 4B, GE Spectra, Siemens P4 or P5, or Square D I-Line. Blank circuit breaker spaces shall be fully bused and ready to accept future circuit breakers. Bus and circuit breaker terminals shall be identified as accepting copper and aluminum cables. Enclosure shall be sized to provide adequate conduit knockout space and gutter wire bending space for future conduits and cables. When aluminum feeder cables are being used, oversize the enclosure for aluminum cables. Enclosures that are too small to accommodate future conduits and cables or aluminum cables (when used) shall be replaced at the Contractor's expense. Door shall have concealed hinge, flush handle, lock with 2 keys, and panel directory frame. All panel locks shall be keyed alike. Lighting and receptacle panels shall be of the voltage, amperage and number of positions shown, 3 phase, 4 wire, 22,000 amps AIC minimum unless shown otherwise, circuit breaker type, with main circuit breaker or main lugs only as shown, copper bus, fully rated neutral and ground bars, NEMA Type 1 enclosure and surface or flush trim as shown. In main circuit breaker panels, the main circuit breaker shall be separate from and not mounted in feeder breaker positions. Load center type panels are not acceptable. Provide circuit breakers as shown. Eaton Pow-R-Line 1 or 2, GE A series, Siemens P1 or P2, or Square D NF or NQOD. Bus and circuit breaker terminals shall be identified as accepting copper and aluminum cables. Enclosure shall be sized to provide adequate conduit knockout space and wire bending space for future conduits and cables. When aluminum feeder cables are being used, oversize the enclosure for aluminum cables.
