Hi Guy's, our 110v Norcold 2118 is been run via a step down transformer from the Spanish 230v system, on our camp site each pitch has 16amp EHU
yes we are not as luck as you guys with 50amp EHU, I have a meter connected into the electric supply input that shows the amount of kws been used, air con, microwave or electric kettle can be used but only ONE AT A TIME.
