Assembly: DC20/60/110 DC circuit breaker/disconnect is
installed adjacent to the DC175/250 breakers on the right side panel for
SW systems and on the left side panel for DR systems. Begin the
installation by removing the topmost nut and one flat washer on the back of
the circuit breaker and install the barrel lug over the stud. Replace the flat
washer followed by the starwasher and the nut, then tighten. Insert the
breaker in the side panel from the inside and secure with two 6-32 x 3/8”
machine screws with #6 internal tooth starwashers. Install the 6 AWG
cable between the hot side of one of the DC175/250 breakers and the
bottom of the DC20/60/110 and the DC60. For PV
systems, connect the DC60 between the PV array and
the C40 charge controller.
