Panelboard metering arrangement and method of assembly thereof

An apparatus, comprising:

• a busbar arrangement, each busbar having a plurality of electrical distribution connection points;
• a current sensor arrangement integral with and in signal communication with the busbar arrangement;
• and
• a metering arrangement in signal communication with the current sensor arrangement, the metering arrangement having at least one of a meter and a meter socket;
• whereby
• a load current passing through each busbar of the busbar arrangement results in a signal at an associated current sensor of the current sensor arrangement and an associated signal at the metering arrangement representative of the associated load current.

A method of assembling a current transformer module integral with a busbar arrangement of a panelboard, comprising:

• arranging a plurality of current transformers in fixed relation with each other to form a current transformer module having the current transformer openings at a predefined spatial relationship, the openings being receptive of busbars;
• coupling the current transformer module to the busbar arrangement by positioning a busbar of the busbar arrangement within each of the openings of the current transformer module;
• and
• fixing the position of the current transformer module relative to the busbar arrangement.
