This heavily constructed spiral-bound reference is filled with essential NEC tables, and the most-used basic electrical, voltage and transformer formulas, examples and illustrations that you can use on the job when you need it most.
You'll find NEC tables that include allowable ampacities, derating, burial depths, grounding, and wire-fill, as well as basic electrical, power, voltage and transformer formulas, examples depicting bending, transformer installations, branch circuits and GFCIs.
All this information fits in a shirt-pocket reference that is there, on the job, when you need it most.
