Description (Brief)
Complex electrical systems rely on components that often attract little attention. This electrical meter socket is like a light bulb socket, it connects the device with the power system. The socket is standardized so that it can accept different manufacturers’ meters, and different types of meters from old analog devices to new digital “smart” meters.
