What Is Remote Power Panel?_
An RPP is a floor-mounted or overhead electrical enclosure that receives high-current three-phase power from the facility’s main distribution switchgear and breaks it out into multiple branch circuits. Each branch circuit feeds a rack PDU, typically via hardwired conduit or overhead busway. RPPs often include metering, monitoring, and circuit breaker protection for each output.
Technical Details
RPPs are typically rated for values such as 225 A to 600 A at 208 V or 480 V three-phase, with output breakers sized per rack load requirements. They are installed in the cold aisle or above the row to minimize cable length and voltage drop. In typical deployments, RPPs are bonded to the facility ground grid per NEC Article 250 and must be coordinated with the upstream transformer’s overcurrent protection. The RPP’s monitoring interface (e.g., Modbus TCP) is integrated into the DCIM system for real-time power usage tracking.
How Leviathan Systems Works with Remote Power Panel
During row assembly, the field crew mounts the RPP on the raised floor or overhead ladder rack, then pulls feeder cables from the facility’s main distribution panel. Branch circuits are terminated to the rack PDUs, verifying phase rotation and load balance before commissioning.
