Description
A slightly angled view of a set of electrical switch boxes and meters for business. They are mounted on the outside wall of a metal sided building. I like the geometrical shapes and patterns and the rustic details. I have enhanced the colors and textures in this version. I also added the one way wording on the sign for privacy. Wonderful for any wall in your home or office, or perhaps a greeting card. Many more wonderful works can be found in my various galleries, from photographs and photo art to digital creations and abstracts. Thanks for browsing, commenting and most of all for any purchases. Debbie Portwood :D..............................Electrical Boxes - A distribution board (or panelboard) is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit, in a common enclosure. Normally, a main switch, and in recent boards, one or more Residual-current devices (RCD) or Residual Current Breakers with Over current protection (RCBO), will also be incorporated.......................North American breaker panels - The circuit breakers are generally placed in two columns. Circuit breaker panelboards are always dead front, that is, the operator of the circuit breakers cannot contact live electrical parts. During servicing of the distribution board itself, though, when the cover has been removed and the cables are visible, North American breaker panelboards commonly have some live parts exposed....................Breaker arrangement - Breakers are usually arranged in two columns. In a US-style board, breaker positions are numbered left-to-right, along each row from top to bottom. This numbering system is universal across various competing manufacturers of breaker panels. Each row is fed from a different phase (A, B, and C below), to allow 2- or 3-pole common-trip breakers to have one pole on each phase. In North America, it is common to wire large permanently installed equipment line-to-line. This takes two slots in the panel (two-pole) and gives a voltage of 240V if the supply system is split phase and 208V if the supply system is three phase..................................................An electricity meter or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device. Electricity meters are typically calibrated in billing units, the most common one being the kilowatt hour [kWh]. Periodic readings of electricity meters establishes billing cycles and energy used during a cycle. In settings when energy savings during certain periods are desired, meters may measure demand, the maximum use of power in some interval. "Time of day" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Also, in some areas meters have relays for demand response load shedding during peak load periods..............(Information source - Wikipedia.com) - (MUCH MORE INFORMATION AVAILABLE AT WIKIPEDIA)
