SynC · Topic
These are the standards in the SynC Standards library that cover Disconnects. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Identification labels, nameplates, warning signs, panel directories, and color-coding for electrical distribution equipment and wiring rated 600V and below and for medium-voltage equipment served by the same project — switchgear, switchboards, panelboards, transformers, motor control centers, disconnects, automatic transfer switches, junction boxes, raceways, and conductors. Covers arc-flash warning labels driven by the arc-flash study, voltage-class and system color coding (normal, emergency, critical, standby, fire alarm, security), panelboard circuit directories, disconnecting-means identification, available fault current marking, and conductor and conduit identification.
