A Terrifying Discovery
We recently experienced one of the most frightening moments of our full-time RV journey – a dangerous electrical failure that could have ended in disaster. This isn’t just another maintenance story. This is about a silent danger that could be lurking in your RV’s electrical system right now.
After returning to our campsite in Florida following a brief two-day absence, we plugged in our Hughes Power Watchdog surge protector as usual, following our normal setup procedure. Immediately, we received a warning light. Our initial thought was that there might be an issue with the campground’s power pedestal, so we called maintenance to check.
When they arrived, we discovered something alarming – a small burn mark on our Power Watchdog surge protector. Little did we know, this was just the tip of the iceberg.
The Shocking Reality
The situation escalated that evening when our power began cycling on and off. Our Victron solar system alerted us that shore power was failing, forcing our rig to switch to battery power. We disconnected everything for safety.
The next day, when Barry inspected our 50 amp cable more closely, we discovered a horrifying sight – the internal copper wiring was completely blackened and burned. This wasn’t just a minor issue; it was a ticking time bomb.
When we cut back the insulation further, we saw that the burning extended deep into the cable, with three of the four wires severely damaged. The copper, which should have been bright and shiny, was charred black.

How Dangerous Was This?
After researching this situation thoroughly, we were shocked to learn just how close we came to disaster:
- When electrical connections fail like this, temperatures can reach 500-700°F – far above the ignition point of many RV materials
- A sustained electrical arc can reach temperatures of 3,000-6,000°F
- The blackened copper indicates temperatures likely exceeded 400°F
- This could have resulted in:
- Complete destruction of our RV’s electrical system
- Damage to appliances and electronics
- Battery system failure
- A potentially catastrophic fire
The experts at Etrailer explained two likely causes: either an electrical arc from a loose connection or simply the wear and tear on cables that full-time RVers experience from frequent connecting and disconnecting.
What Caused Our Problem?
After thorough investigation and help from the campground maintenance team, we discovered the root cause: the metal connectors inside the pedestal’s 50 amp outlet were recessed too deeply. When we connected our surge protector, its weight created just enough pull to cause a poor connection, resulting in arcing and the dangerous heat buildup.
When the maintenance team replaced the outlet with one where the metal connections were properly positioned, our problem was resolved.
Critical RV Electrical Safety Tips
Based on our experience and expert advice, here are vital safety measures every RVer should follow:
1. Regular Inspection
- Visually check all power connections before every hookup
- Look for discoloration, melting, corrosion, or damaged insulation
- Pay close attention to the connection points between cables and plugs
- Inspect your RV’s power inlet for signs of heat damage or corrosion
2. Proper Connection Technique
- Always turn off the pedestal breaker before connecting or disconnecting
- Ensure connections are fully seated and secure
- Use electrical contact cleaner on connections regularly (as Barry demonstrated)
- Never force connections – if they don’t fit easily, something is wrong
3. Equipment Quality and Maintenance
- Replace power cables every 3-5 years if you’re a full-time RVer
- Invest in quality cables with appropriate amperage ratings
- Consider upgrading to Smart Plug systems for more secure connections
- Always use a surge protector like the Hughes Power Watchdog
4. Environmental Protection & Cleanliness
- Keep connections elevated off wet ground
- Use electrical contact cleaner on all connection points regularly
- Clean connections thoroughly when camping in dusty, sandy, or dirty environments
- Remove any debris, insects, or dirt from power inlets and plugs before connecting
- Use weatherproof covers when possible
- Be extra vigilant about checking connections after rain or high humidity
- Consider carrying a small soft brush specifically for cleaning electrical connections
5. Know The Warning Signs
- Flickering lights or intermittent power
- Warm or hot connection points
- Discoloration on plugs or receptacles
- Melted plastic or unusual odors
- Tripping breakers
- Error messages on surge protectors
Our New Setup
After this frightening experience, we immediately replaced our equipment with:
- A brand new Power Watchdog surge protector
- A high-quality Smart Plug Superflex 50 amp cable
These quality components give us peace of mind, but we know that regular inspection is still essential.

Why We’re Sharing This
We debated whether to share this story because it’s a little embarrassing to admit that we missed the warning signs initially. But we realized that if we experienced this dangerous situation after 2.5 years of full-time RVing, anyone could.
This isn’t about scaring you – it’s about potentially saving your RV, or even your life. Take five minutes today to thoroughly inspect your power connections. Look for discoloration, check for secure fits, and consider when you last replaced your power cable.
Remember, when it comes to electrical safety, it’s always better to be overly cautious. As we learned, what seems like a minor issue could be hiding a much more serious problem.
