' <br /> PART 2: PRODUCTS <br /> 2.01 LIGHTING LOAD CENTERS ' <br /> A. Load centus shall be surface mo�nted.Load centers mounted on uninsulatsd masonry walls shall , <br /> be mounted on 1/l inch spacers. 'Ilie bussing shall be suitable for 200 amperes,minimum. The <br /> number of circuits shall be not less than shown on the schedules shovm on the drawings. Load <br /> center shall be NEMA 1, bear the LTL label. and be listed as "suitable for use as service ' <br /> equipment". , <br /> g, Cabinet rough-in brnces shall be code gauge stcel, zinc galvanized on both inside and outside , <br /> s�ufaces,with an iaauned t]ange a�all sides of the front The front covers shall be sheet stcel, <br /> with a nist inhibltar prima and a balced ena�nel finish for s�rface mounted centers. The front <br /> covers shall be fittsd with a door. ' <br /> C. Load center bussing shall be braced at least eq�al to the intem�pting rating of the main <br /> overcurrent device. The losd ca►ter neuual shall have solderless connectors numbered not less , <br /> thaz►the numbu of branch circuits and available spaces in the load center. All spaces shall be <br /> suitable m receive branch circuit breakers. Adjacent breakers shall be connected to alternate <br /> P�• , <br /> D. Unless otherwise definod,main circuit breakers rated at 240 volts shall have an interrupting rating <br /> of not less than 10,000 amps,r.m.s.,sym.,and branch breake.rs shall have an interrupting rating ' <br /> of not less than 10,000 amps, r.m.s., sym. Circuit breakers shall indicate open, closed,or trip <br /> conditions by handle position. Circuit breakers shall be quick-make.quick-break with thermal- � <br /> magnetic trips having long-time and instantaneous tripping characte,ristics. Muld-pole breakers <br /> shall have one handle with handle tie a internal tirip bar with the circuit breaker cases fastened <br /> together. ' <br /> E. Where requind, the load cu►tecs sl�all cantain gro�nd fault interrupting circuit breakers. The <br /> brPakers stiall have an intetrupting rating of not less than 10,000 amps,r.m.s.,sym. The breakers , <br /> sl�all have a sensing circuit capable af tripping the breaker in not more than 30 m.s.at a curnent <br /> inbalance of S m.a. Tl�e breaker shall contain a sensing circnit test feawre. <br /> F. Install cbsu�e pla�es in each space not occupied by a bnaker wh�e the knockout has been ' <br /> ramoved. Accurately list the circuit numbas ai the load center schedule. Fill out the schedule <br /> ntilizing a typ�writa o�block letteis.
