How to Test RV Power Before Plugging In
Before plugging your RV into campground power, it’s important to test the electrical connection. This simple step can prevent serious damage to your RV.
Why Testing Power Matters
Campground power can have issues like:
- Reverse polarity
- Low voltage
- Open ground
- Power surges
Testing helps you avoid these problems.
Method 1: Use a Surge Protector
The easiest way to test power is with a surge protector.
It will:
- Detect wiring issues
- Display voltage readings
- Block unsafe power
Method 2: Use a Voltage Tester
A handheld tester can check:
- Voltage levels
- Wiring conditions
However, it’s less comprehensive than a surge protector.
Step-by-Step Process
- Turn OFF the breaker
- Plug in surge protector
- Turn breaker ON
- Check for errors
- Plug in RV if safe
What to Look For
Safe voltage range:
108V – 132V
Anything outside this range can be dangerous.
Final Tip
Always test power before plugging in — it takes less than a minute and can save you from expensive repairs.
