How do you calculate electrical loads in a commercial building?
A commercial occupancy has a receptacle load of 15,300 volt-amperes and a fixed multioutlet assembly load of 4,860. The total receptacle load is 20,160 volt-amperes. First, subtract 10,000 from the total receptacle load (20,160 – 10,000 = 10,160). Next, multiply the remainder by 50% (10,160 × 50% = 5,080).
How electrical system works in a building?
Introduction. An electrical system, within the context of a building, is a network of conductors and equipment designed to carry, distribute and convert electrical power safely from the point of delivery or generation to the various loads around the building that consume the electrical energy.
Do skyscrapers have lightning rods?
Fortunately, skyscrapers are equipped with lightning rods, usually situated at the highest point of the building, to make it as plausible a target as is possible for the lightning to strike.
