What Do the Common Electrical Acronyms Stand For?
Wednesday, November 09, 2016
Whether you’re trying to replace a part yourself or are wondering about electrical services your HVAC professional has performed, it can be helpful to have an electrical abbreviation reference.
Common electrical services are still somewhat mysterious to the layman, which is why it can be helpful to have a reference for what electrical acronyms stand for. Because such a range exists, it’s unlikely you’ll memorize them all, but we’ll address the major types here and give you a handy reference to use for later.
Electrical Units of Measurement
Units of measurement are one of the most common classes of electrical acronyms. These include, but are not limited to:
Of course, there are plenty of other units of measurement, some of which are not acronyms, but rather are single letters or even Greek letters. For instance, the Omega symbol (Ω) stands for Ohms, a measurement of electrical resistance.
There are quite a few components signified by acronyms. Consider an automatic transfer switch (ATS), current limiting fuse (CLF) or rigid nonmetallic conduit (RNC).
And then there are systems, such as a voltage transformer (VT), roof top unit (RTU) or elevator (ELEV). Other acronyms cover professional associations or regulatory bodies; fields (think HVAC, or heating, ventilation, air conditioning); or basic qualities, such as normally closed (NC), underground (UG) or required (REQ). You can learn about these terms and more by trolling through the Architect's Technical Reference.
