"What's new: The text covers new and updated wiring requirements, including those for peninsular and island counterspaces in kitchens, which have changed significantly, and wiring for receptacle outlets in an attached or detached garage with electric power, which may now supply outside outlets in a limited way (per NEC 210.52(G)(1)). The text teaches students both recognized methods of calculating electrical load on feeders and services and the new or revised 2023 NEC® rules relevant to service installation and surge protection."--Publisher.
