Beginners caravanning: hooking up to electric
Published:
Owning a caravan opens up a world of adventure, giving you the freedom to explore whenever you choose. But before setting off on your first trip, it’s worth getting to grips with some essential basics - one of the first being how to hook up to an electric supply.
It’s a simple process once you know how, and this step-by-step guide will help you get started with confidence.
Step 1: Choose the right pitch
Before setting up, ensure you've booked a pitch with electric hook-up (EHU) access. Most campsites clearly indicate which pitches offer power, but it’s always good to double-check when booking.
Step 2: Check your hook-up cable
You'll need a dedicated caravan hook-up cable, typically 25 metres long with a blue 16-amp plug. Before each trip, check that your cable is in good condition, free from damage or wear. A damaged cable is not only a safety risk but could also cause issues with your connection or appliances.
Step 3: Turn off appliances
Before connecting to power, switch off all electrical appliances inside your caravan. This helps prevent power surges and protects your system. A quick check of lights, the fridge, and heating system takes only a few seconds but can save you a headache later.
Step 4: Connect to the power supply
Locate the external socket on your caravan and plug in one end of the cable. Then, connect the other end to the campsite’s EHU point, ensuring it’s securely in place. A gentle tug will confirm it’s properly connected. Ensure the cable is fully uncoiled to avoid overheating and allow any normal heat build up to release.
Step 5: Switch on the power
Once plugged in, switch on the power at the EHU post (some campsites use key or token-operated systems). Check your caravan’s control panel to ensure everything is working correctly. Many modern caravans have an indicator light to confirm power is coming through. If nothing happens, double-check all connections before seeking assistance.

"Knowing how to hook up to electric safely will ensure your adventures are more comfortable and less stressful, as electricity can be dangerous if not handled properly. When you know how to do it yourself, you’re not relying on others and it gives you access to lights, heating, chargers, and other appliances without draining your battery."

Step 6: Test your power supply
After switching on, test your caravan’s sockets and appliances. Start with something small, like a phone charger, before turning on larger appliances like the fridge or heating system. If there’s no power, check the trip switch on the EHU post and your caravan’s consumer unit (fuse box).
Step 7: Monitor your usage
Campsites typically provide a limited power supply (often 10-16 amps). Avoid overloading the system by using energy-efficient appliances and turning off anything unnecessary. If you plan to use a kettle, toaster, or heater, be mindful that switching them on simultaneously could trip the power. A little planning goes a long way.
Step 8: Disconnecting safely
When it’s time to leave, turn off all electrical appliances and switch off the power at the EHU post. Unplug your cable from the campsite supply first, then from your caravan. Coil the cable neatly and store it safely for your next trip. If it’s wet or muddy, wipe it down - it’s much nicer to handle a clean cable on your next adventure!
Final tips for a smooth hook-up:
- Use a surge protector to safeguard your appliances
- If unsure about the power rating, ask the campsite staff
- Regularly inspect your cables and plugs for wear and tear
- Be considerate - don’t run cables across shared walkways
Once you’ve done it a few times, hooking up to power will feel like second nature. Then, it’s time to relax and enjoy the adventure ahead!
