This article takes a look at the NEC 2017, Section 210.8. We’ll answer questions about GFCI and AFCI protection as it relates to residential washing machines.
Arc Fault Circuit Interrupters (AFCIs) are an important electrical fire prevention and safety requirement of the National Electrical Code. With the changes to the NEC in 2017 there still seems to be questions regarding the use of AFCIs. This primer will address these questions.
The Electrical Service supplying an entire RV park must be sized to accommodate the electrical demands of multiple modern recreational vehicles drawing power simultaneously from the individual park sites.

NEC Article 725 is dedicated to specialized circuitry, different from standard power and lighting circuits. The limited power and voltage of these circuits is what makes them a separate and specialized wiring method.
Let’s take a look at what is happening on the other end of that equipment grounding conductor, and what it is that enables this conductor to effectively carry current at such a rate that it will instantaneously trip a circuit-breaker or fuse, in the event of a ground-fault. It is normal to assume that a conductor will carry current, but in the matter of fault-current it is important to know why an equipment grounding conductor is able to do its job.
The terms Grounding and Bonding are found throughout the NEC text, and while they are seemingly interchangeable terms, they are actually two distinct procedures when it comes to the National Electrical Code, as well as the installation of electrical equipment.
