Abstract

Systems and method are described for a terminal block that can include an insulating block that is composed of an electrically insulating material. The insulating structure can have a first via extending between a first and second opening in the insulating block. A second via can extend between a third and fourth opening in the insulating block. A distance between the first and second openings may be less than a distance between the third and fourth openings. A first electrical conducting element can extend between the first and second openings. A second electrical conducting element can extend between the third and fourth openings. The first and second electrical conducting elements can be separated from one another by a portion of the insulating block.
