B1 copy starts hereB2 copy starts hereB3 copy starts hereInteriorsReliaGear neXT panelboard interiors feature plug-in and bolt-on (when vertical main circuit breakers are selected) technology, IP 20 “finger-safe” features (on clean bus only) and center or offset mounting positions within the enclosure. Main lug, feed-through lug and clean bus options exist. X-height or X-space refers to the space occupied by individual (plug-in) components on the interior bus. One X-space for ReliaGear neXT equals 1.385 inches.2 RELIAGEAR NEXT30" wide circuit breaker panelCenter-mounted interior40" wide circuit breaker panelOffset-mounted interior45" wide circuit breaker panelOffset-mounted interior45" wide circuit breaker panelCenter-mounted interior—01 Typical standard, hinged gutter covers—02 Typical sheet metal fillers cover the space between gutter covers and circuit breakers/blanks—03 Typical sheet metal blanks cover the future space for adding circuit breakers to the interior Standard interior heights• 16X05• 24X05• 32X05• 40X05Interior materials• Tin- and silver-plated aluminum (heat rated)• Tin- and silver-plated copper (heat rated or 1000 A per sq. in. density rated)XT4XT4XT4 XT4XT4XT4XT1XT1XT1XT1XT1XT1FB/TEY FB/TEY225 A04225 A045.5" 5.5"30"XT4XT4XT4XT4XT4XT4XT5XT5XT1XT1XT1FB/TEY FB/TEY8" 5.5"40"600 A04225 A04XT4XT4XT4XT4XT4XT5XT6/XT7XT1XT1XT1FBFB/TEY13" 5.5"45"0302011200 A04225 A04XT4XT4XT4XT4FB/TEY600 A04XT5600 A04XT5XT5 XT1XT4XT4FB/TEY5.5" 5.5"45"Clean bus Main lug Feed-through lug—04Maximum ampacity circuit breaker allowed per this side of interior—05Interiors are double sided; double standard interior heights for available mounting space (Ex. 16X bus has 32X max. of circuit breaker mounting space)

B1 copy starts hereB2 copy starts hereB3 copy starts hereEnclosuresReliaGear neXT panelboards come in three widths (30", 40" and 45") and four heights (60", 72", 84" and 96"). Enclosure sizing is determined by three criteria: 1) wire-bending space required for main device; 2) interior height; and 3) the largest main or branch devices selected. For additional detail, please refer to document 1SQC900008M0201 for NEMA 1, 2, 3R, 4, 4X and 12 enclosure dimensions.4 RELIAGEAR NEXT—Enclosure depths TypeDepthBox Box and front/doorNEMA 1 11" 11"NEMA 1 + DID 11" 14.5"NEMA 2 (with drip hood) 11" 16.3"NEMA 2 + DID (with drip hood) 11" 16.3"NEMA 3R 14.5" * 14.5" *NEMA 4 / 4X / 12 14.5" * 14.8" **Does not include additional depth needed for hanging brackets / handle.—NEMA 1 and NEMA 2 mounting hole locationsHeight Holes A (in) B (in) C (in)60" 4 5 – 872" 4 5 – 884" 6 5 42 896" 6 5 48 8—NEMA 3R, 4, 4X, 12 mounting hole locations Enclosure exterior size (in) Dimension D (in) Dimension E (in)30 (33.5) W x 60 (61.0) H 65.97 24.4730 (33.5) W x 72 (73.0) H 77.97 24.4730 (33.5) W x 84 (85.0) H 89.97 24.4730 (33.5) W x 96 (97.0) H 101.97 24.4740 (43.5) W x 60 (61.0) H 65.97 34.4740 (43.5) W x 72 (73.0) H 77.97 34.4740 (43.5) W x 84 (85.0) H 89.97 34.4740 (43.5) W x 96 (97.0) H 101.97 34.4745 (48.5) W x 60 (61.0) H 65.97 39.4745 (48.5) W x 72 (73.0) H 77.97 39.4745 (48.5) W x 84 (85.0) H 89.97 39.4745 (48.5) W x 96 (97.0) H 101.97 39.47Note: Values in parentheses are overall enclosure dimensions.BAAC CED

General • Panelboards are listed and labeled by Underwriters Laboratories, Inc. in accordance with UL Standards 50 and 67, and shall conform to the latest requirements of the National Electrical Code (NEC) and NEMA Standard PB.1. • The panelboard will meet service entrance requirements when specified.• Boxes are furnished without knockouts. Panel boxes and fronts are cold-rolled steel and furnished with ANS1 light gray polyester textured powder coat. • A four-piece front and hinged gutter covers are provided by default to provide ease of wiring access. All screw fasteners are 1⁄4–20 thread and zinc coated to retard corrosion. • Main and branch circuit breakers shall be quick-make, quick-break and trip-indicating. Interrupting rating of the circuit breaker shall not be less than the maximum short-circuit currents available at the incoming line terminals as shown on the plans. • ReliaGear neXT circuit breakers are compatible with ReliaGear SB switchboards. ReliaGear nexT components are not compatible with any other panelboard type. —Publications Title Document NumberGuideform specification 1SQC900001D0201Assembly Instructions — Factory assembled 1SQC900004M0201Assembly Instructions — Bulk pack 1SQC900003M0201Door-in-door instructions 1SQC900002M0201Dual main lugs 1SQC900009M0201Grounds and neutrals 1SQC900007M0201NEMA 3R, 4, 4X and 12 enclosures 1SQC900008M0201RELT unit 1SQC900005M0201SPD unit 1SQC900006M0201AMP1 main circuit breaker meter 1SQC900001M0201Service entrance barrier 1SQC900010M0201General information1SXU900300G0201, 6.2021—We reserve the right to make technical changes or modify the contents of this document without prior notice.
