Feeder Pillar is a cabinet for electrical equipment, mounted in the street and controlling the electrical supply to a number of houses in a neighborhood. A power box is simply a layman's term for a transformer, cutout enclosure, or other enclosure used in conjunction with underground electrical distribution. In the United States, they are often painted olive drab (an olive-like green color), gray or "sand", a light tan color.
Distribution board, Panelboard or Breaker panel is a component of an electricity supply system that 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 overcurrent protection (RCBO).
A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and switch when they sense one of the sources has lost or gained power.
