Your RV's Lifeline to the Grid
Shore power is how your RV gets electricity from a campground pedestal, your home outlet, or a generator hookup. It feeds your air conditioning, your microwave, your battery charger, and every 120-volt outlet on board. When that connection fails, you're stuck running on battery power alone, and in a Florida summer, that won't last long.
The shore power system starts at the campground pedestal and runs through your power cord, the inlet box on the side of your RV, a transfer switch (if equipped), and into your main breaker panel. Every connection point in that chain is a potential failure point, and Florida's heat, humidity, and salt air make all of them fail faster than they would up north.
30-Amp vs 50-Amp Connections
Most travel trailers and smaller Class C motorhomes run on 30-amp service. That gives you one 120-volt hot leg at 30 amps, which totals about 3,600 watts. It's enough to run one air conditioner, a few lights, and maybe a microwave, but not all at once. If you trip the breaker constantly at campgrounds around Sebastian, you're probably overloading your 30-amp connection.
Larger fifth wheels and Class A motorhomes typically run 50-amp service. That delivers two 120-volt hot legs at 50 amps each, totaling about 12,000 watts. You can run both air conditioners, the microwave, and the water heater simultaneously without breaking a sweat. The plug is a 4-prong design compared to the 3-prong 30-amp plug, and the wiring gauge is significantly heavier.
Using adapters between 30-amp and 50-amp connections is common, but it comes with risks. A 50-amp to 30-amp adapter limits your power to 3,600 watts regardless of what your RV can handle. A 30-amp to 50-amp adapter doesn't give you more power. It just changes the plug shape. We see melted adapters at least twice a month during the busy season at Sebastian Inlet State Park and the Vero Beach KOA.
Common Shore Power Problems in Florida
The number one issue we see is corroded connections. Salt air from the Indian River Lagoon creeps into every exposed terminal and plug prong. Within 6 to 12 months, a connection that was tight and clean can develop enough resistance to cause overheating. We've pulled inlet boxes off rigs at Barefoot Bay with green corrosion completely coating the terminals inside.
Campground pedestal quality is the second biggest problem. Many parks in Indian River County are running electrical infrastructure that's 20 to 30 years old. Low voltage below 108 volts forces your AC compressor to draw more amps to compensate, which can burn out the compressor. Open grounds and reversed polarity can send current through paths it was never meant to travel. We always test the pedestal before connecting your RV.
Damaged power cords are the third most common issue. Road debris kicks up and nicks the cord. UV exposure cracks the insulation. Rodents chew through the jacket. And sometimes people just drive over them in tight campground lots. A compromised cord can arc internally, creating heat that melts the plug end or starts a fire inside the cord itself.
Surge Damage and Protection
Florida averages more lightning strikes per square mile than any other state, and Indian River County sits right in the highest-density zone. A single lightning strike near a campground can send a voltage spike through the pedestal that destroys your converter, your AC compressor control board, your refrigerator circuit board, and your TV in about 200 milliseconds. We've seen $3,000 in damage from a single surge event.
We strongly recommend a hardwired EMS (electrical management system) unit. Progressive Industries and Surge Guard both make reliable units in the $250 to $400 range. They monitor voltage, amperage, and wiring faults continuously. If conditions go out of spec, the unit disconnects your RV automatically before damage occurs. It's the cheapest insurance you can buy for your rig.
What Shore Power Repair Costs
A cord end replacement runs $95 to $150. Full power cord replacement for a 30-amp rig costs $150 to $250, and a 50-amp cord runs $200 to $300. Inlet box replacement is typically $125 to $200. Transfer switch diagnostics and repair fall between $250 and $450. We provide a fixed written quote before we touch anything, and roughly 85 percent of shore power repairs get completed in a single visit because we carry the most common parts on the truck.
All of our shore power work meets NEC Article 551 specifications. That includes proper wire gauges, correct terminal torque values, and appropriate weatherproofing for Florida's coastal environment.

Shore Power Repair FAQ
Most shore power repairs run between $95 and $450. A simple cord end replacement or inlet box swap falls on the lower end at $95 to $175. Replacing a full 30-amp or 50-amp power cord typically costs $150 to $300. Transfer switch diagnostics and repair can reach $350 to $450. We provide a fixed quote before starting any work, so you'll know the exact price upfront.
A 30-amp connection uses a 3-prong plug and delivers one 120-volt hot leg at 30 amps, totaling about 3,600 watts. A 50-amp connection uses a 4-prong plug and delivers two 120-volt hot legs at 50 amps each, totaling about 12,000 watts. Travel trailers and smaller motorhomes typically use 30-amp. Class A motorhomes and larger fifth wheels with dual AC units need 50-amp to run both air conditioners simultaneously.
Common signs include the air conditioner or microwave not turning on when plugged in, a burning smell at the power inlet or cord, visible melting or discoloration on the plug prongs, breakers tripping immediately after connecting to the pedestal, and intermittent power loss where lights flicker or appliances cut out. If your power cord feels hot to the touch after 30 minutes of use, that's a serious warning sign of a loose or corroded connection.
Yes, but it's a significant project. Upgrading from 30-amp to 50-amp requires replacing the power cord, the inlet box, the main breaker, and often the distribution panel. The wiring from the inlet to the panel also needs to be upsized to handle the higher amperage. Expect the full upgrade to cost $800 to $1,500 depending on how accessible the wiring is. It's worth it if you've added a second air conditioner or other high-draw appliances.
Most shore power repairs take 1 to 2 hours on site. A cord end replacement is about 30 to 45 minutes. Replacing a full power cord runs 1 to 1.5 hours. Transfer switch troubleshooting can take 2 to 3 hours because the switch is usually buried behind a panel. We carry the most common cords, inlets, and connectors on the truck, so roughly 85 percent of shore power jobs get finished in a single visit.
Absolutely. Campground pedestals in Florida are notoriously inconsistent. Low voltage, open grounds, reversed polarity, and lightning-induced surges can destroy your converter, AC compressor, and electronics in seconds. We recommend a hardwired EMS unit from Progressive Industries or Surge Guard. They monitor incoming power continuously and disconnect your RV automatically if voltage drops below 104V or spikes above 132V. A good unit costs $250 to $400 and can save you thousands in damaged equipment.
