Preparing for Summer: 2017 NEC Checklist for Installing a Safe, Effectively-Bonded Pool at a Dwelling

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.

A New Method for Measuring Receptacles Located within 6 ft of Kitchen Sink Basins 2017 NEC 210.8

It is no surprise that Ground Fault Circuit Interrupter protection has again been expanded in the 2017 edition of the National Electrical Code. Since its inception in the 1971 edition, GFCI coverage has been expanded and tweaked with just about every code change. In this edition, coverage has been increased in several significant ways, but an important clarification has also taken place. Specifically as regards protection for 15 and 20 amp outlets near sinks, the point at which the measurement is taken as well as the method to be used to measure the 6-foot distance has been clarified.

2017 NEC 210.8(E), GFCI Protection for Crawlspace Lighting Outlets

Ground fault protection is not new, having been introduced in the 1971 edition of the National Electrical Code. GFCI devices have saved many lives since then by preventing shock and electrocution. As you may know, they contain a small transformer that detects current leakage from the phase to the grounded (neutral) conductor. That is why they work even in circuits that do not have a separate grounding conductor. These devices are designed to interrupt current when the leakage reaches a threshold of 4 to 6 mA, just shy of the amount of current that can cause injury to the human body.
