Circuit Breaker Capacity Requirements
Provide a separate circuit breaker for each power cord connected to the server. Each
power cord supplies power to two power supplies. These circuit breakers must
accommodate the facility fault current ratings for the power infrastructure. Standard
3-pole circuit breakers are acceptable. The server has no specific time-to-trip
requirements.
Contact your facilities manager or a qualified electrician to determine what type of
circuit breakers accommodate your facility power infrastructure.
