The improved electric power metering device according to the present invention thus solves many of the issues presented by prior art electricity meters that are installed in or on an individual consumer's premises, such as liability distribution and the potential for injury to the consumer or damage to the metering device based on the proximity of the metering device to the property of the consumer. The improved electric power metering device of the present invention may also be advantageously applied to the electricity distribution grid at various points that prior art meters may not be convenient or possible to install, such that service metering or RSS can be enacted at strategic points in the grid. ## Claims ### Claim 1 A modular power distribution monitoring apparatus,
