Abstract: Systems for improvements in electrical power distribution and monitoring systems for data centers. A system can include a circuit breaker, a set of phased current transformers (CTs), a neutral CT, and a metering device. The circuit breaker can be mounted in a first enclosure. Additionally, the set of phased CTs can be positioned in a first component arrangement of a second enclosure. The set of phased CTs can be coupled to the circuit breaker and be configured to measure a current value flowing through the circuit breaker. Moreover, the neutral CT can be positioned in a second component arrangement of the second enclosure. The neutral No errors found. CT can be coupled to the circuit breaker. Furthermore, the metering device can be configured to transmit data associated with the current value to a display device.
