B. Operation Requirements <br /> 1. The control panels shall consist of a main circuit breaker <br /> and generator breaker with mechanical interlock, an <br /> emergency power receptacle, a motor circuit protector <br /> (MCP) and magnetic starter for each pump motor, and 20 <br /> ampere, 120 volt circuit breakers as required. MCP motor <br /> control panel shall meet all requirements of service <br /> entrance by properly bonding neutral or shall be UL service <br /> entrance rated. A low and high level alarm and pump <br /> shutoff shall be accomplished by float type, liquid level <br /> control system, with all components mounted in one <br /> common enclosure. Control switches shall provide means <br /> to operate each pump manually or automatically. When <br /> operated in the automatic mode, the control assembly shall <br /> provide means to manually select or automatically <br /> alternate the position of the "lead" and "lag" pumps after <br /> each pumping cycle. A three position alternate switch <br /> labeled "test-off-auto" shall be provided to manually select <br /> which pump shall be the lead pump, when necessary, and <br /> also be able to test the alternator to see if it is still <br /> operational. <br /> 2. A float type liquid level control system shall continuously <br /> monitor wet well liquid level and control operation of the <br /> low-level cutoff for the pumps, and shall operate on a 24- <br /> volt circuit. <br /> 3. A non-fused safety switch shall be installed between the <br /> meter and panel. This switch shall be in a NEMA 4X, UL <br /> rated, stainless steel waterproof enclosure, in accordance <br /> with IRCDUS Approved Manufacturer's Product List. <br /> Amperage shall be at least equal to that of the main <br /> breaker. <br /> C. Construction <br /> 1. The electrical control equipment shall be mounted within a <br /> modified NEMA 4X, UL rated, white powder coated <br /> stainless steel, dead front enclosure. The enclosure shall <br /> be equipped with a door and may incorporate a removable <br /> back panel on which control components shall be <br /> mounted. Back panel shall be secured to enclosure with <br /> collar studs. All lines entering the enclosure shall be <br /> protected by conduit seal bushings (supplied by pump <br /> manufacturer) at the source and shall be behind the dead <br /> front enclosure, entering from the side or bottom only. The <br /> seals shall prevent moisture and gas from entering the <br /> enclosure. Two cable connectors (shall be in accordance <br /> with IRCDUS Approved Manufacturer's Product List) shall <br /> be provided to terminate the motor cables in the control <br /> 10 - 7 23, K. 2• <br />
