This standard covers conformance tests and requirements for the enclosure integrity of above-grade padmounted electrical equipment 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 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 enclosure integrity system for pad-mounted equipment providing long service life with minimum maintenance and positive safety features. Revision Standard - Active. Conformance tests and requirements for the coating integrity of above grade pad-mounted enclosures that contain apparatus energized in excess of 600 V and that may be exposed to the general public. 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, and pad-mounted voltage regulators.
