We are going to examine a TIA issued for the 2020 NEC regarding GFCI protection for recreational vehicle (RV) parks, covered in Article 551 of the NEC. The popularity of RVs continues to increase, especially during the pandemic. We also know that GFCI protection continues to be expanded with each successive code cycle. This TIA was published to clarify where protection is required in an RV park. Read more from our blog!

Article 250 is arguably the most important article in NEC 70, and much of its content is devoted to the proper sizing and installation of equipment grounding conductors. First, let us consider the purpose of an equipment grounding conductor (EGC). We know that EGC’s provide a low impedance path from the equipment to the overcurrent protective device (or ground detector for high-impedance grounded systems) so that a fault condition can be quickly cleared. Hence, EGC’s are a critically important safeguard to persons and equipment.

The average consumer does not understand the potential dangers related to electricity and pools, so they rely on you, the electrical professional, to do it right. There have been 98 verifiable water deaths from electricity since 1986, but that is likely just the tip of a very large iceberg. A small amount of current can cause muscular paralysis and drowning. We have put together a basic checklist for electrical safety-related to pools. This list is not exhaustive. We will focus our attention on three important areas: grounding and equipotential bonding, GFCI protection, and corrosive environments.
