Greetings Adam, Here are a couple/few thoughts which may be helpful. Not knowing the specific circumstance(s) or goal(s) these may or may not be appropriate or useful.
Use the 4-8 circuit load center you mentioned with the appropriate circuit breaker and retainer clip and do not twist out the unneeded spaces in the dead front or fill them with the appropriate blanks. Clearly label the load center accordingly and be sure to mark if no other circuits should be installed in it etc. Main Circuit Breaker Disconnect / Circuit Breaker Disconnect: Usually not too difficult to source 60A, 100A, or 125A 120/240VAC double pole main CB disconnects. Install the appropriate 60A CB you need. Confirm the design of specific item you are looking at or ordering meets the retained/fastened in place circuit breaker requirement. Some designed for the HVACR trade for example may not have the ability to retain/fasten the circuit breaker in place. Also; be sure item has the appropriate isolated or bonded Neutral terminal to meet your needs, as well as the equipment grounding lug/terminal. Disconnect may be designed for use as service equipment and these may be separate part numbers and/or disconnect may be field convertible. If acceptable for the project, use a suitable fused disconnect switch with the required 60A fuses. Wire line and load sides of switch accordingly for the circumstances at hand and to meet code and be sure to label clearly identifying purpose and the hazards of the switch as installed. Comment above regarding Neutral and EGC terminals apply here as well. May need to order separately. An appropriately rated panel mount double pole circuit breaker installed in a small panel mount type enclosure may be an option as well to meet your requirement. This may be a good option especially if you need a solution which will take up as little space as possible. MidNite Solar may have an appropriate enclosure/box. The appropriate double pole circuit breaker may need to be researched with CBI-electric North America or Safe Circuits, Inc. in Pennsylvania. I have dealt with this issue in various circumstances before, such as needing to install backfed circuit breakers. I do not recall the specific brands and part numbers used, but the major US market manufacturers should have a solution to meet your needs. Hopefully your local electrical supply company can come up with a solution for you, but if still in need I suggest calling Schneider/Square D, Eaton/Cutler-Hammer, or Siemens etc. Third party retainers may also be available which could work with a load center and circuit breaker you may already have, but be aware your local AHJ may not allow a retainer which is not listed/recognized for use with the load center and circuit breaker. Also; we need to remember that in the case of backfeeding a circuit breaker we must make certain it is rated for backfeed, not marked "Line" and "Load". I hope that I understood your question correctly and that some of these thoughts may be helpful. Best regards, ----MATT Matthew Sirum P.O.

The QO retaining clip (PK2MBCP) seems to only be compatible with their 4-8 circuit load centers. What are my options? Thanks!
