Renogy DCC30S wiring diagram, 8 AWG (10 mm²) positive feed protected by a 40 A fuse and a matching negative return between the 12 V battery bank and the unit, plus 3 × positive input, PV −.

The run drawn here is the 10 ft reference run sized below. Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. Confirm your own run length, routing and terminations before ordering — open this part in the designer to size it against your actual system.

02 — Reference run

What size cable and fuse does the DCC30S need?

Conductor8 AWG10 mm²
Fuse40 Apositive run
Voltage drop2.7%10 ft one way
Design current30 A12 V system

Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The design current is the unit's rated output. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 10 ft one-way run is a stated reference, not a universal installation prescription.

04 — Supporting parts

What else you need to wire the DCC30S

  • 20 ft total of 8 AWG (10 mm²) marine cable
  • Four 8 AWG cable lugs matched to the equipment studs
  • 40 A fuse and holder on the positive run
  • Heat-shrink, strain relief, and terminal boots sized to the cable

Catalog profile

The manufacturer, model, ratings and terminal map are maintained as planning data in Crimp's component catalog. Confirm the current manufacturer manual, exact revision and installed nameplate before ordering or wiring.

Engine reference

Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
