Mains Power Circuit Breaker

Safety is important, and connecting the mains power to devices in the vehicle needs to be done with great care. I got two circuit breakers: a 2 Pole Miniature Circuit Breaker for 16A, and a Crabtree 2 Pole Residual Current Circuit Breaker 80A 30mA. Important is that these circuit breakers cover both poles, because when connecting power to a European power outlet, it is not identified which pole has the "load". In UK the power plugs are polarized, which means one clearly knows which of the two poles is the "load" line. But most European plugs are not polarized, so the load could be on any of the two poles. Therefore, both must be protected with a 2 pole circuit breaker.

I also got a volt and ampermeter, which measures the current and the power. This is very useful for campsites with limited power supply.
