Up for bid is a 12 Volt DC Power distribution panel with fuses that come off of a J/30 that was being parted out. See pictures for measurements. No batteries in boat when removed, so I could not test, but Vessel did not sink. Panel has plug that plugged into boat wire harness, I wasn't able to unplug this plug (with a little effort it may unplug), but it would be best to use a terminal block to attach to boat wiring anyway. Sold for parts / repair as is. Please check out my other listings for more quality marine equipment (Diesel engines, transmissions,  fuel tanks, self tailing winches, electronics, Compasses,  sails, etc) and other quality items. I'm always updating my inventory, so save me as a seller to keep up to date with my offering. Good Luck, Happy Bidding!!!
