IEEE C57.12.28-2014

This standard covers conformance tests and requirements for the integrity of above grade pad-mounted enclosures containing apparatus energized in excess of 600 V that may be exposed to the public including, but not limited to, the following types of equipment enclosures: – Pad-mounted distribution transformers – Pad-mounted capacitors or inductors – Pad-mounted junction enclosures – Pad-mounted metering equipment – Pad-mounted switchgear – Pad-mounted voltage regulators This standard does not cover installations that are under the exclusive control of electric utilities and that are located in such a manner that access to the equipment is controlled exclusively by the utility.
The purpose of this standard is to describe the requirements for a comprehensive integrity system for pad-mounted enclosures providing long field life with minimum maintenance and positive safety features.
Revision Standard – Superseded. Conformance tests and requirements for the integrity of above grade pad-mounted enclosures that contain apparatus energized in excess of 600 volts and that may be exposed to the public including, but not limited to, the following types of equipment enclosures: pad-mounted capacitors or inductors, pad-mounted distribution transformers, pad-mounted junction enclosures, pad-mounted metering equipment, pad-mounted switchgear, and pad-mounted voltage regulators are covered.
