Electrical Maintenance Glossary – Terminology & Abbreviations

Understanding an invoice from an electrical contractor can be tricky. The electrical industry is rife with tla’s – three letter acronyms, technical jargon, and industry speak.

At Keece, we attempt to remove the complexity from our communications. Thus keeping our quotes and invoices easy to understand. We use this “trade dialect” of English all day long. Sometimes we fall guilty of expecting our customer to understand it as well. This post is a summary of  the electrical terms and abbreviations used within our maintenance team – our electrical maintenance glossary. We hope it can help you.
