Power Fundamentals
A circuit breaker interrupts current under normal switching or fault conditions. Breaker ratings must match voltage, continuous current, interrupting duty, protection scheme, and system fault levels.
EPA's eGRID is a database of electric generation and emissions attributes by grid region and plant. It is useful for estimating location-based emissions, but users should understand reporting year, regional boundary, and market-based procurement differences.
Read definition →Interconnection is the physical and electrical connection of a facility to the grid or to another electric system. For data centers, the term can refer to utility service connection, transmission-level large-load process, on-site generation connection, or fiber/network interconnection depending on context.
