Technical Vocabulary

1. Alligator - A specialized tool attached to a hot stick used to tie a wire or cable into an insulator. (Caimán)
2. Autotransformer - A transformer in which at least two windings have a common section. They are use to either "buck" or "boost" the incoming line voltage. (Autotransformador)
3. Blackout - Complete interrupting of load to an electric utility customer or group of customers. (Apagón)
4. Circuit breaker - A device that can be used to manually open or close a circuit, and to automatically open a circuit at a predetermined level of over current without damage to itself. (Pastilla Termomagnética)
   
5. Conduit - A channel for holding and protecting conductors and cables, made of metal or an insulating material, usually circular in cross section like a pipe. Also referred to as Duct. (Tubería para cable)
6. Luminaire - A complete lighting unit consisting of a light source with a means of distribution (reflector and/or refractor), lamp positioning (socket), lamp protection (housing) and a provision for power connection. (Luminarias o lámparas fluorescentes)
7. AWG - American Wire Gauge: A measure of wire thickness (which also dictates cross-sectional area, and for a given material, ampacity). (Calibre de alambre Estadounidense)
   
8. Ampacity - The amount of current a conductor can carry without exceeding its specified temperature, in amperes. (Amperaje)
9. Relay - electromagnetic switching device consisting of an armature which is moved by an electromagnet to operate one or more switch contacts. (Relevador)
10. Three phase - It refers to one circuit consisting of three conductors where the current and voltage in each conductor (phase) is 120° out of phase with each other phase. (Sistema Trifásico)
