Busbar support, made up of two parts, comprising an attachment between the two parts

A support for a busbar, comprising:

• a first part comprising:
• a first base comprising a hole or a fastener and a first bearing surface configured to bear against a substrate;
• a first sub-part extending from the first base, the first sub-part defining a first lower mating surface and a first upper mating surface spaced apart from the first lower mating surface by a first angle;
• and
• a first attachment feature;
• and
• a second part comprising:
• a second base comprising a hole or a fastener and a second bearing surface configured to bear against the substrate;
• a second sub-part extending from the second base, the second sub-part defining a second lower mating surface and a second upper mating surface spaced apart from the second lower mating surface by a second angle;
• a second attachment feature having a shape that is complementary to a shape of the first attachment feature;
• wherein the first base and the second base are configured to be arranged with the first lower mating surface abutting the second lower mating surface and with the first upper mating surface abutting the second upper mating surface, wherein the first angle and the second angle define a through-cavity or a passage;
• and
• wherein the first attachment feature and the second attachment feature are configured to engage one another to provide an attachment between the first part and the second part.
