Middle Atlantic MPR-JB843A – MPR Raceway Junction Box, 8 x 4 x 3 Inch
Product Overview
The Middle Atlantic MPR-JB843A is an optional junction box that mounts on the end of a Middle Atlantic MPR raceway to provide a code-friendly wiring termination point for vertical power distribution. Measuring 8 inches deep by 4 inches wide by 3 inches high, this MPR raceway J-box is equipped with electrical knockouts for conduit and cable entry. Steel construction with a black finish matches the MPR raceway system it serves. It is the narrowest of the MPR junction box sizes, suited to compact rack power feeds.
Product Description
Middle Atlantic MPR Series raceways distribute power vertically along the rack rail, and every hardwired raceway installation needs a clean place to land the electrical feed. The MPR-JB843A junction box attaches to the end of the raceway and gives the electrician a dedicated enclosure for making those connections. Pre-punched electrical knockouts accept standard conduit fittings, so the incoming branch circuit can be routed into the box without field drilling.
At 8" x 4" x 3", the MPR-JB843A is the 4-inch-wide member of the MPR junction box family; wider 5-inch (MPR-JB853A) and 6-inch (MPR-JB863A) versions are available when additional wiring room is required. The steel enclosure carries the same black finish as MPR raceways, keeping the completed assembly uniform inside equipment racks and credenzas. For integrators standardizing on MPR vertical power distribution, pairing each raceway with the appropriate J-box simplifies rough-in coordination with the electrical contractor and keeps line-voltage terminations enclosed and serviceable.
