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 wire is another type of wire used quite a bit in the industry. THHN / THWN wire is used in all Romex cables and UFB cables with different protective jackets that allow it to be used in different applications. THHN wire has a PVC insulation with a nylon coating to protect against weather, gas and solvents.t can be used outdoors or in conduit but it cannot be direct buried without the use on conduit. Our underground cables listed in awg sizes above are very useful and not that expensive. UFB cable can be used in any way you need outdoors because weather and moisture have no change on penetrating the UFB jacket.
