IEEE P2406

New IEEE Standard - Withdrawn - Draft.
This Standard is a basis for the design, application, and usage of direct current non load (no-load) break disconnect switches for the purpose of isolating direct current power distribution circuits for transit applications.

This standard covers basic design parameters and features for Non-Load Make or Break Direct Current Disconnect switches used on Transit systems for isolation applications.
This Standard covers design criteria of direct current disconnect switches pertaining to current and voltage ratings, physical clearance spacing for gap and creep, and auxiliary control equipment.
Special considerations not addressed in this Standard or beyond the scope of this Standard should be considered by specific owners on a case by case basis. The intent of this Standard cannot cover these instances.
