phase-to-ground insulation
1Ground and neutral — For uses of the term ground or earth in electricity but not in the context of mains wiring, see ground (electricity). Since the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely… …
2Split-phase electric power — A split phase electricity distribution system is a 3 wire single phase distribution system, commonly used in North America for single family residential and light commercial (up to about 100 kVA) applications. It is the AC equivalent of the… …
3Thermal insulation — The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer.Heat energy can be transferred by conduction, convection, radiation or when undergoing a phase… …

5Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the …
6Electrical wiring — in general refers to insulated conductors used to carry electricity, and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring …
7Seasonal thermal store — A seasonal thermal store (also known as a seasonal heat store or inter seasonal thermal store) is a store designed to retain heat deposited during the hot summer months for use during colder winter weather. The heat is typically captured using… …
8Busbar — A busbar in electrical power distribution refers to thick strips of copper or aluminium that conduct electricity within a switchboard, distribution board, substation, or other electrical apparatus.The size of the busbar is important in… …
9AC power plugs and sockets — See also: Industrial and multiphase power plugs and sockets Plugs and sockets may sometimes combine male and female contacts, but t …
10Earthing system — In sulvent systems, an earthing system defines the electrical potential of the conductors relative to that of the Earth s conductive surface. The choice of earthing system has implications for the safety and electromagnetic compatibility of the… …
