Static transfer switch rapidly transfers a load between two power sources when one source falls outside acceptable limits. It can improve source redundancy for critical loads but adds controls, fault-current, and coordination complexity.
Electrical room is a dedicated space for switchgear, panels, transformers, UPS equipment, or distribution equipment. Room size, access, clearances, fire separation, cooling, and maintenance paths can constrain usable data hall planning.
Read definition →Scope 2 emissions are indirect emissions from purchased electricity, steam, heat, or cooling. Data centers are often Scope 2-intensive because electricity use dominates operational emissions.
