A power strip (also known as an extension block, power board, power bar, plug board, pivot plug, trailing gang, trailing socket, plug bar, trailer lead, multi-socket, multi-box, socket board, super plug, multiple socket, multiple outlet, polysocket and by many other variations) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket. Power strips are often used when many electrical devices are in proximity, such as for audio, video, computer systems, appliances, power tools, and lighting. Power strips often include a circuit breaker to interrupt the electric current in case of an overload or a short circuit. Some power strips provide protection against electrical power surges. Typical housing styles may include strip, rack-mount, under-monitor and direct plug-in.
