Abstract: Exemplary electrical disconnects may include a housing defining a first access at a first end of the housing and a second access at a second end of the housing. The second access may extend vertically along a height of the housing beyond a vertical location of the first access. The electrical disconnects may include a busbar characterized by a first segment and a second segment. The first segment and the second segment may be coupled at a break section of the busbar. The first segment of the busbar may extend through the first access of the housing. The second segment of the busbar may extend through the second access of the housing. The electrical disconnects may include a pyrotechnic initiator disposed within the housing. The electrical disconnects may include a blade laterally aligned with the break section of the busbar.
