Parallax 088-0001-001 DC Fuse Board · 15 Circuits wiring diagram

Parallax 088-0001-001 positive-only DC board, identified by its printed label: nominal 12 V, 100 A maximum total, fifteen ATC fuse circuits. Maximum branch fuse: 30 A on circuits 1–2 and 20 A on circuits 3–15; these are limits, not installed fuse values. Three positive lugs are common and unfused; an output from a lug needs separate protection. Draw negative returns on a separate bus. No converter is included. Verify the installed assembly label: the older 5300 guide shows an 85 A / 20 A revision, so this board does not establish a 100 A rating for every 5355.
