MNTransition Instructions Introduction The MNTransition is designed to provide a transition from expensive wire from the panels to more economical wire for the rest of the installation. Important! This unit can not be used as a disconnect. A separate disconnect means is required in the system. Note: The plastic dead front fits very tight. You must first remove the lid in order to remove the deadfront. Remove the deadfront: Pry off the lid as shown using something like a screwdriver as a lever.

This dimensioned drawing shows the location and size of knockouts available on the MNTPW. Note that the center bottom knock out is sized for a 1 1 /4” conduit adapter. The left and right side each have a ½” knock out for either wire entry or for lightning arrestors. Lightning arrestors may require a locknut on the outside in order to clear the lid. The MNTPW is a type 3R rainproof enclosure.
