Can I purchase a PDU without a circuit breaker?

Yes, some configurations can be purchased without an internal circuit breaker. All Geist’s PDUs require an appropriately sized branch circuit breaker in the building installation. Branch circuit breakers should be sized according to the PDUs namplate rating, and electrical code requirements. To comply with the NEC the circuit breaker in the building installation should have a trip current rating that is 25% higher than the PDU’s nameplate. For example, a 16A rated PDU requires a 20A circuit breaker.
