Generally, <br />receptacles and appliances are on separate circuits from lighting. <br /> <br />Branch panel circuits are numbered to match NEMA pole numbering system; poles l <br />and 2 - Phase A; poles 3 and 4 - Phase B; poles 5 and 6 - Phase C, etc. Actual field <br />numbering of circuit directories may vary from pole numbers, but is phased and pole <br />connection as shown. <br /> <br />No. 14 wire will be permitted only on control circuits of relays, contactors, starters, etc. <br />No. 12 wire will be a minimum size for any lighting, motor, or general branch circuits <br />unless specifically noted otherwise. <br /> <br />In general, conductor sizes for major branch circuits, such as large motor and <br />equipment branch circuits are noted. Where conductor sizes for such circuits are not <br />noted, provide branch circuits with conductors sized as follows: <br /> <br />Conductors for Individual Motor Branch Circuits: Have ampere capacity of not <br />less than 125% of the full load running current of the motor. <br /> <br />Conductors for Multiple Motor Branch Circuits: Have ampere capacity of not <br />less than 125% of the ruJming current of the largest motor plus 100% of the <br />running current tbr each additional motor connected to the circuit. <br /> <br />Where specific conductor sizes required by the Drawings and Specifications are larger <br />lhan Code requires, the larger sizes are installed. <br /> <br />Circuits may be arranged in four-wire feeds (three circuits and common neutral) in <br />color code previously described; more than three circuits in conduit when in <br />compliance with applicable NEC Article 310. <br /> <br />DISCONNECT SWITCtlES <br /> <br />Disconnecting devices, when not included with electrically-operated equipment <br />furnished under other sections of this Specification, provided and installed under this <br />section. <br /> <br />Safety switches quick-make, quick break, heavy duty, horsepower rated, with voltage <br />rating as required by the system and current rating as scheduled or as required by the <br />motor manufacturer. Switches in a NEMA I enclosure with a defeatable cover <br />interlock unless specified as NEMA 3R on plans or otherwise required. Switches non- <br />fusible except where otherwise noted. <br /> <br />BASIC MATERIALS AND METHODS 16050-7 <br /> <br /> <br />
