When we say the right extension cord matters, this is not us being dramatic. The plug already handled that part for us. 😅
Here’s a recent job we did where the cord being used to power this RV wasn’t rated to safely carry the electrical load. It overheated badly enough that the plug and outlet melted together, creating a very real & dangerous fire hazard.
We removed the damaged equipment, installed a new outdoor receptacle with a weatherproof cover, and replaced the cord with one properly rated for the RV’s electrical demand.
Extension cords aren’t one-size-fits-all. The correct cord depends on:
• How many amps the equipment requires
• The cord’s wire gauge and amperage rating
• The length of the cord
• Whether it is rated for outdoor use
• The condition of every plug and connection
Just because a cord fits doesn’t mean it can safely power what’s connected to it.
If a cord, plug, or outlet ever feels unusually warm, smells like burning plastic, looks discolored, sparks, or begins to melt, stop using it immediately. The damaged components should be replaced, and the entire setup should be inspected before being used again.
Electrical safety often comes down to the details that are easy to overlook, until they become a much bigger problem.
If you’re unsure whether a cord, outlet, or electrical setup is safe for what you’re powering, Harmon Electrical Services is happy to take a look. ⚡️
