Frequently Asked Questions

Q: How much can I safely run at once on my caravan mains hook-up without tripping the site supply?ⓘ

Most UK campsite hook-up bollards cap out at 16 amps, and some sites abroad only offer as little as 5 amps - go over whatever your particular pitch provides and you'll trip their breaker, not just a fuse in the caravan, so it's worth asking the site what your pitch is actually rated for before you plug in. As a rough guide to what's drawing power at once: a fridge on electric typically pulls around 0.5 amps, a TV about 2.5 amps, the battery charger roughly 1 amp, a microwave close to 10 amps, air conditioning around 4 amps, and a blown-air or convection heater about 8.7 amps, and a 2kW kettle draws around 8.7 amps too.

Add up whatever you're planning to run together and keep the total comfortably under your site's stated limit.
