1. A three-phase selectable energy meter comprising:
- a base;
a phase A terminal barrel, a phase B terminal barrel and a phase C terminal barrel;
a phase selection member movably engaged with the base, the phase selection member permitting individual selection of each of the phase A terminal barrel, the phase B terminal barrel and the phase C terminal barrel, wherein the individual selection of the one of the phase A terminal barrel, the phase B terminal barrel or the phase C terminal barrel prohibits selection of the other two of the phase A terminal barrel, the phase B terminal barrel and the phase C terminal barrel,wherein the phase selection member includes;
a conductive strip; and
an actuation member holder movably attached to the conductive strip, the actuation member holder including three apertures respectively corresponding to the phase A terminal barrel, the phase B terminal barrel and the phase C terminal barrel; and
a terminal bracket coupled to the base and the phase selection member, the terminal bracket including three apertures respectively corresponding to the phase A terminal barrel, the phase B terminal barrel and the phase C terminal barrel,wherein the three apertures of the terminal bracket are uniformly separated by a first distance,wherein at least two of the three apertures of the actuation member holder are separated from one another by a second distance distinct from the first distance,wherein one of the three apertures of the actuation member holder is configured to align with one of the three apertures of the terminal bracket, simultaneously mis-aligning two of the three apertures of the actuation member holder with two of the three apertures of the terminal bracket.
