The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
The Code Question of the Day (CQD) is NECA and ELECTRICAL CONTRACTOR Magazine’s flagship National Electrical Code (NEC®) public forum for the industry. The daily distribution of Q&A generates a lively dialogue and shares relative Code-based practical responses.

Hi Code Question of the Day, does Section 680.26 require a continuous bonding grid around a permanently installed pool, or can the required items each be run back individually to a common bonding point? Thanks, Nathan K.

Hello CQD. I have heard that GFPE protection is now required on shore power receptacles at marinas rather than standard GFCI. Is that correct under the NEC, and what is the required trip threshold? Thank you, Eric B.
Hello Eric, that is correct. Article 555 covers marinas and boatyards, and Section 555.35 requires GFPE protection rated to trip at 30 milliamperes for shore power receptacles supplying boats — rather than the 5 mA ground-fault circuit interrupter protection used elsewhere. The 30 mA threshold is grounded in US Coast Guard studies and research by the American Boat and Yacht Council Foundation, which found that level prevents a majority of electric shock drowning incidents while remaining practical for marina applications. Section 555.35(E) also requires a listed leakage current measurement device at marinas where more than three receptacles supply shore power, so individual vessel leakage can be identified before it accumulates in the water around the dock.
