IEEE C57.12.28:1999

New IEEE Standard - Superseded.
Conformance tests and requirements for the integrity of above-grade pad-mounted enclosures that contain apparatus energized in excess of 600 V 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, and pad-mounted switchgear are covered.

This standard covers conformance tests and requirements for the integrity of above grade pad-mounted
enclosures containing apparatus energized in excess of 600 volts that may be exposed to the public
including, but not limited to, the following types of equipment enclosures:
a) Pad-mounted capacitors or inductors
b) Pad-mounted distribution transformers
c) Pad-mounted junction enclosures
d) Pad-mounted metering equipment
e) Pad-mounted switch gear
This standard does not cover installations that are under the exclusive control of electric utilities and 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.
