A complete electrical reference library small enough to fit in a toolbox. This unique guide contains tables, charts, graphs, diagrams and terminology relating to the field of electricity that includes: formulas and laws, wire ampacity, conduit and box fill, raceway and wiring specifications, motors, overload protection, transformers, lighting, low voltage, symbols, conversion factors. abbreviations, definitions, materials, tools, and more.
Figuring electrical formulas can get pretty complicated. This amazing little guide is like an encyclopedia that fits in your toolbox, for when you need to reference or double check an on-the-job question. Here youíll find Ohmís laws on power formulas, impedance, AC and DC current. Youíll also find power factor formulas, horsepower formulas, voltage drop formulas, circuit characteristics, resistance, inductance, capacitor ratings, fuel cells and batteries, and sizes of panelboards, gutters and wireways, disconnects, pull boxes and junction boxes. Youíll find conduit specs, wire specs, grounding electrode conductors, sizes of conduits, couplings, chase nipples and bushings. Youíll learn typical wiring methods for communications, labor units for fiber optics; cable selection criteria, common fiber optic connectors, designing motor circuits, DC motors; cost-savings in motor power formulas, motor trouble-shooting, transformer connections, voltage levels, recommended light levels, fluorescent lamp troubleshooting, and much more.
