Are Your Motorhome Electrics Safe Without an Earth?

Could your motorhome electrics be putting you at risk without you realising it?

This week, Motorhome Matt and Keith get into one of the most misunderstood topics in motorhome and campervan ownership, earthing. If your van is sitting on four rubber tyres, where does the electricity go when something goes wrong? And what really happens when you plug into a campsite hook-up, run an inverter, or power the van from a portable power station?

Matt is joined by Mark Street from BlueFix to explain the difference between mains hook-up, 12V systems, inverters and portable power stations. They cover what “earth” actually means in a motorhome, why your van behaves differently on campsite hook-up compared with off-grid power, and what can go wrong when a portable power station is used to feed the van’s sockets. It’s a useful listen for anyone running kettles, chargers, coffee machines or hair straighteners in a motorhome or campervan.

Plus, Campervan Campout is on from 1 to 3 May 2026 at the South of England Showground in Ardingly, with camping, live music, talks, advice sessions and Creator’s Day.

And in the Q&A, Matt answers your questions on:

• What might be causing a cat pee smell in a motorhome cab
• Why fuel prices can jump so quickly, and what it means for European touring
• Whether you still need to carry breathalysers when driving in France

If you use hook-up, an inverter, a portable power pack or anything with a three-pin plug in your motorhome, this is one to listen to before your next trip. We’ll help you understand the risks, the myths and when it’s time to get someone qualified involved.
