Book excerpt: This guide book started out as a simple code basics guide for my own employees. I was finding that when we wired a detached garage, or something else we didn’t do all the time, there would be some confusion on how to do it properly, what the codes were, etc. I’m all about training at my own company and came up with a guide that would cover of all these situations. My employees could keep it in their trucks and pull it out, when needed. For example, if they were going to install a Tesla charger next week, they could reference the section in this guide book to refresh their memory. This early company guide morphed into "Residential Electrician Field Guide". This guide includes many of the important residential codes, explained in a normal "non lawyer talk" way. One of the most frustrating things about our National Electrical Code book is that it is hard to read! My goal was to break down the codes and explain them in simplest fashion possible. This guide is over 200 pages including over 75 diagrams and tables. Some of the items included in this guide: * NEC 2020 code changes * Under ground wiring * Detached garage wiring * New work and old wiring wiring installations * Arc-Fault protection * GFCI protection * Related codes to lighting and outlets throughout all different rooms in a house * EV charger installations * Service upgrade installations * Load Calculations * Knob and tube inspections * HVAC wiring * Cable and CAT lines * My thoughts on electrical inspectors * Massachusetts Amendments to the 2020 NEC * Some business thoughts * And much much more! If you are a residential electrician or someone interested in it. I believe this to be the perfect guide for you!
