If you’ve ever found yourself onsite and wondered if you could run the microwave at the same time as the kettle to warm baked beans and make tea, this tool will help you not make the trip to the EHU to reset, or worse still ask the warden to help…

- Plain-English verdict — safe, close, or over
Amps vs watts — the bit people mix up
Watts are what appliances use. Amps are what the site supplies. Divide watts by 230 to get amps. Exceed your site's amp limit and the breaker trips — usually at the bollard.

Important note
This is a guide tool. Always check the actual amperage shown on your pitch bollard and your caravan's own consumer unit. Some sites vary. Never rely on memory alone.
