Electrical Hookups 101: Pick the Right Plug for Your Motorhome

If you’ve ever arrived at a campsite only to find your lights flicker or your fridge won’t run, you know how frustrating a bad electrical hookup can be. The good news? Getting the right plug and adapter is easier than you think. In this guide we’ll walk through the most common plug types, how to match them to your motorhome, and a few tricks to keep the power steady.

Common Plug Types in the UK

Most UK campsites use one of three standard connectors: the 13‑amp “European” plug (often called a “13A” or “IEC”), the 15‑amp “British” plug, and the 32‑amp “hard‑wire” supply. The 13‑amp plug is the most common for small motorhomes and caravans – it fits a standard UK socket and can power lights, a TV, and a small fridge. The 15‑amp version provides a bit more juice, useful if you have a larger fridge or a heater. The 32‑amp hard‑wire is found at premium sites and can run the whole motorhome, including air‑conditioning and multiple appliances.

When you book a pitch, the site usually lists which plug they offer. If they just say “electricity available”, ask for the exact type. Knowing this ahead of time saves you a trip back to the depot for a new cable.

How to Choose the Right Adapter

Even if the campsite has the right plug, your motorhome might need an adapter. Most motorhomes are fitted with a 13‑amp socket, so if you land at a 15‑amp site you’ll need an adapter that steps the voltage down safely. For 32‑amp sites, you’ll need a heavy‑duty adapter and a dedicated cable – these are sold at most motorhome supply stores and usually come with a built‑in fuse.

Here’s a quick checklist before you hit the road:

• Check your motorhome’s manual for the maximum amp rating of the onboard socket.
• Match the campsite plug to that rating. If the site offers a higher rating, grab the proper adapter.
• Bring a spare fuse of the correct size. A blown fuse is a cheap way to lose power on the night.
• Inspect the cable for any cuts or frayed ends. A damaged cable can cause sparks.

Having these items in your checklist means you’ll spend less time troubleshooting and more time enjoying the view.

Another practical tip is to test the connection before you plug anything in. A quick “click” of the plug into the socket should feel firm; any wiggle suggests a loose fit, which can lead to overheating.

If you’re travelling across borders, remember that continental Europe uses a different plug shape (the two‑pin “Euro” plug). A universal adapter kit covering the UK, EU, and US types costs less than £20 and can be a lifesaver on a cross‑country trip.

Finally, keep your power usage in mind. Even with the right plug, overloading the circuit will trip the site’s breaker. A good rule of thumb is to keep total draw below 80% of the plug’s rating. For a 13‑amp socket, that means staying under about 10 amps – roughly the power needed for lights, a fridge, and a small TV.

By knowing the plug types, carrying the right adapters, and watching your amp draw, you’ll never be left in the dark again. Plug in, power up, and enjoy the freedom of motorhome travel without the stress of electrical headaches.
