Mabru Sea Air 5000 wiring diagram, 10 mm² (8 AWG) positive feed protected by a 60 A fuse and a matching negative return between the 12 V battery bank and the unit.

The run drawn here is the 3 m reference run sized below. Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. 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 Sea Air 5k need?

Conductor10 mm²8 AWG
Fuse60 Apositive run
Voltage drop2.5%3 m one way
Design current28 A12 V system

Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The design current is the part's continuous draw. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 3 m one-way run is a stated reference, not a universal installation prescription.

What else you need to wire the Sea Air 5k

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

What is known, assumed, and computed.

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. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
