Common questions
What does a RV surge protector do?
An RV surge protector protects your RV’s electrical system from voltage spikes and surges. It also detects wiring faults like reverse polarity, open ground, and high/low voltage, shutting off power if a dangerous condition is detected.
Do I need a waterproof surge protector?
Yes, if you camp in areas with rain or humidity. Even if you don’t often camp in wet weather, condensation can occur. Waterproof models have sealed casings that prevent moisture from damaging the electronics.
What is the difference between 30 amp and 50 amp surge protectors?
30 amp surge protectors are for smaller RVs with a single 120-volt line. 50 amp protectors are for larger RVs with two 120-volt lines, providing up to 12,000 watts. Always match the surge protector to your RV’s power requirement.
Can I leave my surge protector plugged in during rain?
Yes, if it is waterproof. Most portable surge protectors are designed to be weatherproof, but it’s recommended to unplug when not in use to prevent wear and tear.
How do I know if my surge protector is working?
Most models have indicator lights or a digital display that shows voltage and status. Some have a test button. If the display shows an error code, it may indicate a problem with the power source.
What is a joule rating and why does it matter?
Joule rating indicates the amount of energy a surge protector can absorb before it fails. A higher joule rating means better protection and a longer lifespan. For RVs, look for at least 1000 joules, but 2000 or more is better.
Do surge protectors have a lifespan?
Yes, surge protectors degrade over time as they absorb surges. Some models have indicator lights that show when protection is diminished. It’s recommended to replace your surge protector every few years or after a major surge event.
Can I use a regular household surge protector for my RV?
No, household surge protectors are not designed for the outdoor, high-amperage conditions of an RV. RV surge protectors are built with weatherproofing and are rated for 30 or 50 amps. Using a household one can be unsafe.
What is the difference between a surge protector and an electrical management system?
A surge protector only protects against voltage spikes. An electrical management system (EMS) also monitors and protects against low/high voltage, open neutral, and other wiring faults. EMS devices are more expensive but offer comprehensive protection.
How do I install a portable surge protector?
Portable surge protectors are easy to install: simply plug them into the campground pedestal, then plug your RV’s power cord into the surge protector. Make sure the pedestal is turned off during installation to avoid sparking.
The verdict
For most RVers, the Camco 44200 offers the best balance of protection, durability, and value. If you want smart monitoring, the Hughes Power Watchdog is worth the extra cost. For 50-amp rigs, the Hughes PWD50-EPO is the top choice.
