The default rod type, STD, includes manually-driven ¾ INCH x 10 FEET [3.05 METER] copper-clad ground rods with studs, clamps, etc. The electrolytic rod types, EL-L (3 FEET vertical x 10 FEET horizontal [0.91 x 3.05 METER]) and EL-S (straight 10 FEET length [3.05 M]), include pipe with weep holes, electrolytic filling material, special conductive backfill material, and protective cover. If the number of ground rods is not specified, 4 rods are generated for the first FEET [ METER] of grid cable, then 1 rod for each 200 FEET [61 METER] thereafter. For example, a 10 FEET [3.05 METER] length generates 4 rods, a 200 FEET [61 METER] length generates 5, and 1,000 FEET [305 METER] generates 9. Does not include trenching and backfill.

Interrupt Capacity: LV: MVA; MV: MVA; HV: MVA Breaker type: Defualt: *FEED* FEED - Feeder breaker MAIN - Main breaker TIE - Tie breaker : *AIR*, SF6, VAC 8 Motor control center MCC Floor-mounted assemblies of one or more enclosed vertical sections principally containing combination motor control/overload protection units (starters). Range: LV: HP [ KW] MV: HP [ KW] Voltage: LV or MV : *S*, I The MCCs described below are intended for inside use (i.e., are not for outside use local to the motors). They are unaffected by the electrical class/zone specifications covered later in this chapter. The intelligent MCCs provide more sophisticated electronic control and communication to a control center. The cost for upstream items are not included (e.g., supply bus duct/cable; switchgear [feeder breakers, metering, substation disconnect switch, main breaker]; and substation transformer). There are two types of MCC available in the system (see diagram below)- those which supply electric motors driven at low voltage (MCC-LV: COA 733) and those driven at mid-voltage (MCC-MV: COA 744). The MCC-LV may contain starters for motors and as well as circuit breakers for other small electrical loads (LIGHTING TRANS. BRKR- to supply panelboards feeding lights, electric tracing, control center hardware). The MCC-MV contains only starters for motors. The MCC-LV is a 12-NEMA space cabinet; the MCC-MV is a 3-NEMA space cabinet. This item is specified by the HP [KW] rating of the motor being supplied- this permits the system to select an appropriately sized starter (see table below). The resulting cost includes both the cost of the starter as well as the cost for the fraction of the cabinet occupied by the starter. For example, assume that you specify a 20 HP [15 KW] rating- the reported cost for the MCC-LV is the cost of the 3-space starter plus three-twelfths of the whole cost of the cabinet. Specifying four such items would, in effect, completely account for the cost of one 12-space MCC-LV containing four 3-space starters. - Continued - ICARUS Corporation, G3
