Double insulation is a design concept where failure of one insulation system will not expose the user to a shock hazard due to the presence of a second independent layer of insulation. Reinforced insulation is a supplemental insulation system that is strong enough to effectively perform as if a double insulation system was present.
Class II insulation means that the device is double insulated. This is used on some appliances such as electric shavers, hair dryers and portable power tools. Double insulation requires that the devices have both basic and supplementary insulation, each of which is sufficient to prevent electric shock. All internal electrically energized ...
The energy efficiency rating in this HERS represents the predicted energy consumption, represents the form of normalized annual energy consumption. This rating scheme consist a detailed measure of CFLs, water heater tanks, ceiling, floors and pipe insulation , efficient refrigerator and freezer, high efficient space and water heating equipments ...
This is usually achieved at least in part by having at least two layers of insulating material between live parts and the user, or by using reinforced insulation. In Europe, a double insulated appliance must be labelled Class II or double insulated or bear the double insulation symbol: ⧈ (a square inside another square). As such, the ...
The Home Energy Saver website includes a section called LEARN which offers tips about energy savings, an explanation of the house-as-system energy efficiency approach, and other information to help people understand how energy is used in a home. When launched in 1994, Home Energy Saver was the first and only online home energy calculator.
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.

The value of clearance relates to the electrical insulation, and the possibility of arc flash between two electrically energised parts (or between live and grounded parts). Higher voltages require higher clearances. For double insulation the clearances must be doubled.
