Expansion units are used to accommodate the expansion and contraction of a busbar system as well as allow for building movement. They allow for a 40mm movement along the length of the busbar.
Expansion units are recommended when a straight busbar run exceeds 60m. They are installed in the centre of long busbar runs, or at the beginning of riser runs to minimise the stress on the lower section of the busbar run.
