Power Strips
Power Strips
A power strip, also known as a relocatable power tap (RPT), is a device that provides multiple electrical receptacles from a single power cord and plug. Unlike surge protectors, power strips do not necessarily provide protection from voltage transients or electrical surges. Many power strips consist solely of outlets, internal wiring, and, in some cases, an integrated circuit breaker and power switch.
Power strips are among the most common forms of residential and commercial power-distribution equipment. Although visually similar to surge protectors, many power strips provide no surge-suppression capability and serve only to distribute electrical power to multiple devices.
Overview
Power strips are commonly used in homes, offices, workshops, entertainment systems, and information technology environments where additional power outlets are required. They are available in a wide range of outlet counts, cord lengths, and configurations.

Historical Notes
Relocatable power taps became increasingly common in residential and office environments during the late twentieth century as the number of electrically powered consumer devices increased.
While surge suppressors often receive greater attention from collectors and researchers, ordinary power strips provide valuable insight into electrical-safety standards, manufacturing practices, materials, and product evolution. Many power strips remained in service for decades despite receiving little documentation from manufacturers.
Collector Notes
Many older power strips remain functional for decades; however, age, physical damage, environmental exposure, and degraded insulation may create safety concerns. Devices documented by OldSurge.com are presented primarily as historical artifacts and reference examples.
