IEEE C57.12.29:2014

Revision Standard - Active.
Conformance tests and requirements for the integrity of above-grade pad-mounted enclosures for application in coastal environments that contain apparatus energized in excess of 600 V and that may be exposed to the public are described. These include, but are 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.

This standard covers conformance tests and requirements for the integrity of above-grade pad-mounted enclosures intended for installation in coastal environments 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.
