Glossary of Electrical Enclosure and Cabinet System Terms

This glossary is a practical reference for everyone who works with electrical enclosures, their installation or the selection of a suitable cabinet type.

It provides information about the different enclosure systems (3D, AHVO, Modul, PS1 and PS2), the materials used, enclosure marking methods and specialised PER electricity meter enclosures.

Each term is explained briefly and clearly to help you understand enclosure construction, installation options, dimensional compatibility and specific technical parameters.
The glossary is intended to help you navigate our product range and provide quick explanations of terms commonly encountered by designers, installation technicians and electricity distributors.

We regularly add to and update the glossary in response to new products, system changes and the requirements of electricity distributors.
