1. An intelligent electronic device (IED) comprising:
- a housing;
a base coupled to the housing, the base including a first side oriented toward the exterior of the housing, a second side oriented toward the interior of the housing, and at least one aperture for receiving at least one first connector, the at least one aperture extending from the first side to the second side;
a multi-conductor cable including a first end and a second end;
the at least one first connector coupled to the first end of the multi-conductor cable, the at least one first connector including a receptacle, wherein when the at least one first connector is disposed through the at least one aperture, the receptacle is accessible via the first side of the base; and
at least one second connector coupled to the second end of the multi-conductor cable, the at least one second connector configured to be coupled to at least one function module disposed within the housing.

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.

18. An intelligent electronic device (IED) comprising:
-
an input base module sub-assembly configured to be coupled to an electrical distribution system; and a metering sub-assembly including at least one current sensing circuit configured to sense current from the electrical distribution system received via the input base module sub-assembly, the metering sub-assembly being hindgedly connected to the input base module sub-assembly such that the input base module sub-assembly is configured to be pivoted about the metering sub-assembly to achieve an open position and a closed position relative to the metering sub-assembly, wherein, in the open position, the metering sub-assembly is configured to receive at least one card to expand the functionality of the IED, and the input base module sub-assembly includes at least one aperture configured to receive a cable coupled to the received at least one card such that the received at least one card is accessible external to the IED. - View Dependent Claims (19, 20)
