Sparkync:
The 'MOP' or MOCP, is the maximum fuse or cb for the unit, based on the mfg nameplate. You may provide protection (CB/fuses) of any rating between 65.7 and 110.
As to the CB and panel...you have to check first which one has sufficient 'spare' amperage capacity for the new load. Time for a load calc or a recorder. When you determine which panel can handle the new load, that is the one ya get a CB for.
