The Weekly Facebook Live show RVing in New England, hosted by the New England RV Dealers Association (NERVDA), was scheduled to discuss grounding monitor interrupters (GMI), which are loss-of-ground devices.
Co-hosted by Bob Zagami and John DiPietro, the show airs at 7 p.m. EDT on Wednesdays. Recordings can be found on the duo’s podcast site here.
“A new electrical safety device will be required on all new RVs manufactured beginning late 2026,” show coordinators said. “It’s called a GMI for Grounding Monitor Interrupter, which is a loss-of-ground device that confirms the chassis of a camper trailer or motorized RV is properly bonded (grounded) to the campground pedestal ground.
“The GMI is mounted inside of the RV itself, NOT the campground pedestal. If the GMI inside the RV doesn’t detect a proper low-resistance ground connection from the pedestal, it will disconnect the connection to the shore power cord and won’t allow AC power to reach the RV’s electrical system.
“Mike Sokol is joined by Ryan Bergen, Campground Design Services, and Eric Rathburn, VP Real Estate Development for KOA. They will discuss the challenges and opportunities from the campground owner’s perspective when GMI equipped RVs show up in late 2026 and early 2027. The time to discuss this is now, not when campers show up at your campground. Join us for this candid discussion as everyone learns more about GMI devices.”
