Got Electric’s alphabetical list of electrical terminology continues to appear in a series of posts. Be sure to keep this detailed list handy!
Electrical Terminology: T - U
1. Three Phase: #Three-phasepower is a three-wire AC power circuit with each phase ac signal 120 electrical degrees apart.
2. Three-way switch: Multiple location points to access power. For example, having more than one switch to control one light.
3. Transfer Switch (ATS/MTS): A device that transfers power from its original source (like a power line). An ATS (or Automatic Transfer Switch) connects to two sources of power. If one source fails, power from a backup source, like a generator, will kick in. An MTS (or Manual Transfer Switch) manually changes power sources if one fails. For example, if the power goes out, simply flip the MTS to switch to generator power.
4. Traveler: A wire that carries voltage through a multi-way switch as in between two #three-wayswitches. This offers two potential pathways to complete the circuit.
5. Underground: Electrical circuits that are located beneath the ground, rather than above as in power lines. This is often a safer (protecting from elements like snow and ice) and aesthetically pleasing option.
