Identify Junction, Pull, and Connection Boxes: Identification of systems and circuits shall be pressure-sensitive, self-adhesive label indicating system voltage and identity of contained circuits on outside of box cover. Color code shall be same as conduits for pressure. 1203 defines the requirements and guidelines for DC power distribution identification by colour and marking in Telecom/ICT installations (wire, cables, electric distribution boards, interconnections, etc. This is an internal LLNL standard meant to guide the design of new facilities, facility. When designing low-voltage and medium-voltage systems, a complete set of distribution panel symbols helps engineers, CAD designers and contractors understand how power flows through switchboards and panel boards. Using a standard DWG legend for breakers, meters, transformers and control devices. Building Automation System (BAS): Blue and Green. Lighting Control Cabling shall be Green. 3 Underground Electrical Line Identification: Install line markers for all underground wiring, both direct-buried and in raceway. Provide metal tags securely fastened to wire and cable in manholes, hand-holes, vaults and underground pull boxes.
