Load-conductors / knockout removal
The bottom end-walls / knockout plates on the back-wall can
be removed from the enclosure for ease of knockout removal.
Once knockouts for required conduit/ conductors are punched
out, the bottom end-wall or knockout plate can be re-installed.
Conductors can be pulled through the knockouts before re-in-
stallation of the plates to the enclosure.
