What is PME Pad?
PME Pad-Mounted Gear’s medium-voltage components are completely encased in an air-insulated grounded steel compartment. This provides protection from wildlife, foliage, and contaminants that, in live-front gear that isn’t properly maintained, can make contact with live components and cause faults.
What is a PME switch?
S&C Manual PME Pad-Mounted Gear brings in-air insulation, in-air switching, and quick, convenient, fuse handling to elbow-connected, dead-front gear. Three-phase in-air switching of source circuits is accomplished with externally operable Mini-Rupter® Switches.
What does PMH stand for electrical?
Manual PMH Pad-Mounted Gear Operation.
What is Pad Mounted switchgear?
PSI/II Pad-Mounted Switchgear is designed to meet the switching and isolating requirements of electrical distribution systems with 15 pre-engineered switching configurations. There are UL®-listed standard units available to cover almost every situation – radial feed, loop feed and manual primary-selector switching.
Who owns S&C Electric?
S&C was founded in 1911 by Nicholas Conrad, who coinvented the first high-voltage power fuse. The company now has annual sales over $500 million, operates in six countries, and has 2,500 employees worldwide. The ESOP currently owns 75% of the company.

Do I need an earth rod with PME?
Since 2013 earth rods have been required on PME systems and the flexibility that some installers used to not fit an electrode was removed from the 18th Edition in January 2019, but the difficulty of successfully fitting an earth rod predates both regulations.
Why is PME used?
The advantage of using the combined conductor in this way is that it provides a low impedance return path which ensures rapid disconnection of the supply under fault conditions. Where PME conditions apply, the returning current has two possible paths, through the combined conductor and the general mass of Earth.
