Which type of equipment would be needed to expand a data center containing a single Power Distribution Unit with ample power capacity but no extra breaker or panelboard capacity for additional equipment?

The need to expand a data center with a single Power Distribution Unit (PDU) that has sufficient power capacity but lacks additional breakers or panelboard capacity can be addressed by implementing a Remote Power Panel (RPP).

An RPP is specifically designed to provide additional distribution points for power, allowing for the connection of more equipment without overloading the existing PDU. It effectively extends the power distribution capabilities, making it ideal for situations where the main PDU is at its limit in terms of panelboard capacity but where more capacity is needed for additional devices. The RPP can house multiple circuit breakers and distribute power to various loads, making it an essential component for scaling power infrastructure in data centers.

Other equipment choices, such as a Medium Voltage Power Distribution (MDP), Uninterruptible Power Supply (UPS), or Manual Transfer Switch (MTS), serve different purposes. An MDP is used for larger distributed systems and higher voltages, a UPS provides backup power during outages but does not expand distribution capacity, and an MTS facilitates the transfer of power sources rather than adding additional circuits. Thus, for the specific requirement of expanding capacity through additional breaker space, an RPP is the appropriate solution.
