In the US typical household power consumption is about 11,700 kWh each year, in France it is 6,400 kWh, in the UK it is 4,600 kWh and in China around 1,300 kWh. The global average electricity consumption for households with electricity was roughly 3,500 kWh in 2010.ur household electricity use has been 2,000 kWh each of the last few years, which means it is about 700 kWh per person. We benefit from not using electricity for heating or cooling, although our electric oven is a big source of demand.
THHN stands for Thermoplastic High Heat Resistant Nylon, so just from the name we are able to tell that the wire is made of thermoplastic material, can withstand high temperatures, and features a nylon jacket.
THHN stands for Thermoplastic High Heat-resistant Nylon-coated. THHN is a designation for a specific insulation material, temperature rating, and condition of use (suitable for dry and damp locations) for electrical wire and cable. Wire with THWN or THHN insulation is commonly used in the AC electrical distribution systems throughout North America, usually at voltage levels from 110 to 600 volts. This type of insulation is used for both copper and aluminum conductors which are either solid or stranded, depending on size.
