DEC STD 002

DEC STANDARD 002 REV.C is an internal document from Digital Equipment Corporation that defines comprehensive requirements for AC power wiring, safety grounding, receptacles, and electrical rating information applicable to Digital's hardware products.

The standard's primary purpose is to ensure product compliance with national and international electrical codes and safety standards for installation and use. Key areas covered include:

• Specifications for power cord conductors (e.g., color coding, wire sizes).
• Requirements for power entry methods, including various voltage conversion methods to accommodate diverse AC power sources (e.g., 120V/240V, single-phase, three-phase).
• Detailed safety grounding requirements for equipment, including ground wire specifications, connection methods, and cabinet grounding.
• Specifications and configurations for power receptacles and plugs.
• Requirements for electrical rating information to be displayed on product nameplates (e.g., voltage, frequency, current, power).

Notably, the document explicitly states that it excludes signal grounding requirements, focusing solely on product safety related to AC power. It is designated "FOR INTERNAL USE ONLY."
