When boltedconnections are preferred, cubicles may beused in place of plug-in units. Cubicles can alsobe used at ampere ratings that exceed standardplug-in unit ratings. Modifications to cubiclescan be made in order to accommodate keyinter-locks, ground fault detector systems andpower monitoring systems.In-Line Disconnect CubicleHorizontal14 BUSWAYSYSTEMSVerticalExpansion Fittings, Dimensions (standard/min.)Dimensions Inches (mm)Ampere Rating“A”AL L-Rated225 — 13 (330)400 — 13 (330)600 — 13 (330)800 400 13 (330)1000 600 13 (330)1200 800 18 (457)1350 1000 18 (457)1600 1200 18 (457)2000 1350,1600 18 (457)2500 2000 23 (584)3000 2500 23 (584)3200 2000 23 (584)4000 3000,3200 25 (635)CU M-Rated225 — 13 (330)400 — 13 (330)600 — 13 (330)800 400 13 (330)1000 — 13 (330)1200 600 13 (330)1350 800 13 (330)1600 1000 18 (457)2000 1200,1350 18 (457)— 1600 18 (457)2500 2000 18 (457)3000 — 23 (584)3200 — 23 (584)4000 2500,3000,3200 23 (584)5000 4000 25 (635)Expansion FittingsExpansion fittings accommodate for expansionand contraction of a busway run and buildingmovement. Expansion fittings typically areinstalled in the center of long busway runs, andat the beginning of riser runs to minimize stresson the lower most device or where a buswayrun crosses an expansion joint of a building.Expansion Fittings are recommended when therun exceeds 200 ft. (608m). Expansion fittingsallow for a +/- 2 in. (50.8mm) movement alongthe length of the busway system.Expansion FittingSuffix XPFT 24.0" (610mm) for isolated ground.Siemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog 14-35
