Full Description

Scope

This standard covers ratings, construction, and testing of dead-front control switchboards containing but not limited to devices such as switches, control devices, instrumentation, metering, monitoring, protective and auxiliary relays, and regulating devices and accessories.

Purpose

This project will modify all dimensional information to provide metric dimensions. This is necessary to gain global acceptance of this standard. Also, due to changes in related standards (e.g. C37.20.1 and C37.20.2) revisions will be made to provide similar requirements between these related standards.
