To connect your RV to shore power, confirm that the campsite’s electrical service matches your setup, turn off the pedestal and RV main breakers, and securely connect the shore cord before restoring power. Use the correct cord and any approved adapter, and manage appliance use within the available service rating. Turning breakers off before connecting or disconnecting helps prevent arcing and damage at the plug.
A shore cord is the heavy-duty electrical cable that connects your RV to an external power supply, such as a campground pedestal.
Shore power supplies the RV’s AC electrical system. It also allows the converter or inverter/charger, depending on your equipment, to supply DC power and charge the house batteries.
Your RV may have either:
Use a cord designed for your RV’s electrical service. Never alter the plug, remove its ground pin or defeat the grounding connection. A molded plug alone cannot guarantee that the campground outlet is correctly grounded.
Check your RV’s power inlet, cord markings and owner’s manual to identify its service requirements.
A properly wired 50-amp RV pedestal uses a 120/240-volt configuration. The RV distributes power from the hot legs to its 120-volt circuits. This differs from a 30-amp RV connection, which requires 120-volt service.
Do not connect to an outlet simply because it looks similar or an adapter makes the plug fit. Have campground staff or a qualified electrician resolve any uncertainty about the supply.
Before plugging in, check the shore cord, connectors and pedestal receptacle.
Look for:
Do not use damaged equipment. Report a damaged pedestal or loose receptacle to campground staff.
Position the RV so the cord reaches without pulling tightly against either connection. Route it away from vehicle traffic and places where it could be pinched or damaged.
Turn off major AC loads, including air conditioners, electric heaters and other high-draw appliances.
Turn the RV’s main breaker OFF. At the pedestal, turn the breaker for the receptacle you will use OFF as well. For 50-amp service, both hot legs must be switched off.
If the pedestal breaker is inaccessible or its condition is uncertain, ask campground staff for assistance before connecting.
A battery disconnect controls battery-connected circuits; it does not replace these AC breaker steps.
For a detachable cord, connect the RV end first while the pedestal end remains unplugged.
Align the connector with the RV inlet, seat it fully and engage its locking mechanism as directed. Secure the locking ring if equipped.
Then insert the campground plug squarely and completely into the matching pedestal receptacle.
The twist-lock connection generally applies to the detachable RV inlet. Do not assume the campground plug also twists into place.
For a permanently connected cord, pull out the required length and connect its plug to the appropriate pedestal receptacle.
With the connections secure:
If a breaker trips, reduce the electrical load and investigate before resetting it. Repeated trips, unusual heat, buzzing or a burning smell require attention. Stop using the connection and seek assistance.
An approved RV adapter can allow a 50-amp RV to connect to a 30-amp campsite receptacle. However, the available supply remains 30 amps total.
You may need to avoid running several high-draw appliances together. Air conditioners, microwaves, electric water heaters and portable heaters can quickly consume the available capacity. Battery charging also contributes to the load.
An adapter changes the connection; it does not create additional electrical capacity.
Call ahead to confirm the service available at your campsite, especially if operating multiple air conditioners is important to your stay.
Use adapters intended for the specific RV connection and service rating, with grounding maintained throughout.
If an extension is necessary, use an appropriately rated RV extension cord and follow your owner’s manual. Keystone’s guidance specifies a 30-amp, 10-gauge extension no longer than 50 feet for the described 30-amp application. That specification does not apply to 50-amp service.
Keystone also directs owners not to combine adapters or reducers with an extension cord or connect multiple extensions together. Ask your dealer to confirm the correct arrangement if the supplied cord will not reach.
Turn off AC appliances and the RV main breaker, then turn off the pedestal breaker.
Grasp the plug body and pull it straight out of the pedestal. Do not pull on the cable. Disconnect the RV end of a detachable cord afterward, then inspect, coil and store the cord.
Review Chapter 8 of your Owner’s Manual before your next trip to confirm the hookup requirements for your RV.
