A power strip is a block of electrical sockets that attaches to the end of a flexible cable, 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 flow of electric current in case of an overload or a short circuit. Some power bars provide protection against electrical power surges. Typical housing styles may include strip, rack-mount, under-monitor and direct plug-in.
