This may be to charge the battery or pre cool the fridge before a trip.
The supply is protected by a Residual Current Circuit Breaker but I still think it is safer to turn the supply off.....meddling hands and all that!
I also don't like to think I could be supplying the power to a thieves grinder to aid them to remove my security devices!
