This power supply is a large metal box with honey-comb grating on four sides that expose the electronic components inside. The casing on the front includes five dials labeled "Fuse", and three silver switches. This front panel is removable. At the back the grating fills 1/3 of the machine. To the left of the grating is a rubber hole for a black cable. Next to the cable is a brown rectangular panel with five female cable connectors. Underneath on either side there are two yellow sticker parts. There is a round silver plug with "Turn and Pull/ Cover Grounded/ Hubbell Twist-lock" in indended letters.
