9.2 Luminaires and Circuits
9.2.1 Luminaire type and voltage rating for each area of the facility shall be as
specified on the Data Sheet.
9.2.2 Outdoor lighting shall be controlled automatically. Photocell control,
provided with time delay and other protection to negate the effect of
lightning, is preferred. The method of photocell control shall be as specified
on the Data Sheet. In areas where plant flares, clouds of dust, and similar
conditions exist, an astronomical clock should be used. The astronomical
clock shall be specified on the Data Sheet, when required.
9.2.3 Standby lighting shall provide minimal egress lighting in operating areas in
the event of a power failure. These luminaires shall be circuited and run
separately from general lighting. The type of standby lighting shall be as
specified on the Data Sheet.
9.2.4 Battery-powered stand-by lights shall be provided in the control room,
substation buildings, and other locations as specified on the Data Sheet. Exit
signs need to be illuminated during the loss of normal lighting.
9.2.5 The loss of a luminaire or lighting circuit shall not leave any area in
darkness.
10. Power Receptacles and Convenience Outlets
10.1 120-Volt Receptacles
10.1.1 The 120-volt receptacles shall be located in process units so that equipment
at grade can be reached with extension cords not longer than 50 feet unless
specified otherwise on the Data Sheet.
10.1.2 All receptacles located in washdown areas or in other areas having wet
atmospheric conditions shall be equipped with weatherproof covers and
boxes.
10.1.3 All 120-volt receptacles located in non-classified areas shall be
NEMA 5-20R unless specified otherwise on the Data Sheet.
10.1.4 Ground-fault circuit-interrupter (GFCI) protected receptacles shall be
provided where required by the NEC and where specified on the Data Sheet.
10.2 480-Volt Receptacles
10.2.1 All 480-volt receptacles shall be three-wire, four-pole, and three-phase and
shall be installed in convenient locations within 150 feet of areas in which
480-volt power to portable equipment is required. The 480-volt receptacles
shall be 60A unless specified otherwise on the Data Sheet.
10.2.2 All four-pole receptacles shall be of the same size and rating.
10.2.3 A maximum of four (4) receptacles shall be connected to one feeder. Feeder
cable sizes shall be based on a demand factor of 0.5.
10.2.4 480-volt receptacles shall match the plug type indicated on the Data Sheet.
