Have you never known a circuit breaker to trip at the campsite? It happens when you use more electricity than is available in the campsite’s EHU.
You will often need to use the coffee machine, refrigerator, heating system and maybe the heater fan in the awning all at the same time. That’s when the circuit breaker trips. You can either choose not to use one of the devices or install an Alde load monitor.
The load monitor reduces boiler output while you’re brewing coffee or making toast. Once your coffee is brewed, the boiler supplies the desired output again. This lets you avoid tripping a circuit breaker and enjoy your coffee and glorious Alde heating.
