In 2006, the second edition of IEC 62271-200 was prepared by subcommittee SC17C and the project was assigned to maintenance team 14. The major change of IEC 62271-200, edition 1. 0, is the revision of new definitions and classifications of equipment of metal-enclosed switchgear and controlgear.

The qualification of a new design of a metal-enclosed switchgear and controlgear is done by several type tests. The personal protection due to an internal fault in medium voltage metal-enclosed switchgear became in IEC 62271-200 a significant higher importance. This class is intended to ensure a tested level of protection to persons in the vicinity of the electrical equipment in normal operating conditions and with the switchgear and controlgear in normal service position. The internal arc class makes allowance for internal overpressure acting on covers, doors, etc. C for pole mounted metal enclosed switchgear.

A specification for a plug and socket that look similar, enclosed medium voltage switchgear and controlgear.

Some of which are listed in the IEC technical report TR 60083, the requirement for insulated pins was introduced in the 2004 revision. Still widely used in modern Russia, but lacks the insulation sleeves.

The accessibility of type C is restricted to installation out of reach. The test arrangement shall include fully equipped test objects. Mock-ups of internal components are permitted with the same volume and external material as the original items and with no influence on the main and earthing circuit. The test shall be performed in every compartment of the switchgear and controlgear containing main circuits. Extensible modular units shall be tested in all compartments at the end of a minimum arrangement of two units. The replacement of SF6 with air is permitted, but the pressure rise will be different.
