1. An intelligent electrical device (IED) comprising:
- an input base module sub-assembly including a base having a plurality of apertures, a first current input blade disposed through a first aperture of the base and a second current input blade disposed through a second aperture of the base;
a metering sub-assembly including a first current plate disposed on a first surface of the metering sub-assembly and a second current plate disposed on a second surface of the metering sub-assembly opposite to the first surface, the first current plate hingedly coupled to the first current input blade and the second current plate hingedly coupled to the second current input blade such that the input base module sub-assembly is configured to be pivoted about the first current plate and first current input blade and the second current plate and second current input blade to achieve an open position and a closed position relative to the metering sub-assembly,wherein the first current plate is coupled to the second current plate such that the first current input blade, the first current plate, the second current input blade, and the second current plate form a first current input path; and
at least one current sensor that senses current flowing through the first current input path.

Abstract
An intelligent electronic device (IED) is provided. The IED includes a metering sub-assembly and an input base module sub-assembly. The metering sub-assembly is hinged to the input base module sub-assembly, where when in an open position, various cables, connectors, and input/output cards/modules are accessible. Various input/output cards/modules are interchangeable to add/change functionality and/or communication capabilities to the IED.
