A shore power connector was built to carry current, not to carry a cord.
In our bench measurement, a 50 amp cord held at 36 inches put 3.0 to 3.8 lb on its connector. Strain Guard carries the weight instead. No tools. No wiring. Works with the cord you already own.
Load test, 2 August 2026. Scale calibrated on camera. It took 8.06 lb of upward force to first lift the 50 amp cord’s weight off the connector. Strain Guard held 10.91 lb before it released.
without connector support, a 50 amp cable has a downward weight of between 3.0 and 3.8 pounds on a connection made to carry current.
Heavy power cables pull down on the connection point. That pull works the connector loose over time, and a loose contact makes heat — even when the power itself is perfectly normal.
Heat softens the plastic and takes the spring out of the metal. Less spring means less contact pressure. Less pressure means more resistance, and more resistance means more heat. It feeds itself until something melts.
The U.S. Fire Administration counts about 4,200 RV fires a year, from all causes, with an average loss of $15,350.
In 2019 ours caught fire. We found it in time. Not everyone does.
What you say matters.
That is why our feedback form is right here on the front page. No hunting for a contact page.
Tell us about your rig, your setup, and what you’ve run into with your cord or inlet. We read every message and we answer. What you tell us shapes what we build next.
