Hi Peter:
> I believe rating markings, energy efficiency ratings, EMC and > Radio markings should be harmonized worldwide and > governments/regulators should be involved to train consumers > the meaning these markings. As a consumer, why do I need to know the meaning of EMC and Radio markings? As a consumer, I only need to know efficiency ratings at the time I choose the appliance/equipment. Such ratings need not be a permanent part of the equipment, but can be on a disposable tag. There is no post-purchase need for such data. As a consumer, I simply plug the equipment into the wall outlet. The equipment is pre-configured for voltage and is provided with the proper plug for my house. I don't need to know voltage, current, watts, or frequency ratings of the equipment. If a house circuit-breaker trips when I turn on my equipment, I may need to know the current or power rating of my equipment in order to balance the load on the circuit. So, who are the rating markings for? The certifiers and regulators. The ratings could just as well be in the accompanying documents.
