Cable sizing for this example

Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.

3 m one way

12 V system

Wire: 6 mm² · 10 AWG
Example fuse: 25 A
Design current: 18 A
Voltage drop: 2.7%

Sized against ABYC E-11. The design current is the unit's rated output. The length is one way; voltage drop includes an equal-length return.

Run-length and manufacturer assumptions

The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.

Verified against the manufacturer's documentation (rev. 811.0421 BA / EN — 15.09.2015, EBL 119 / EBL 119 with OVP), checked 2026-10-01. Manufacturer documentation →

Which part of the EBL 119 is represented?

The EBL 119 is an integrated motorhome power unit containing a mains charger, distribution circuits and battery switching. This catalog entry deliberately covers only its mains-to-house-battery charging function: AC L/N/PE and house charging positive/negative. Starter-battery maintenance charging, alternator coupling, refrigerator branches, solar input and the control-panel harness are real functions described in the manual, pages 7–10, but are not connected or simulated by this symbol.

This limited model avoids turning controlled battery connections into a permanent parallel bus. It is not a replacement for the vehicle's complete EBL wiring plan. The overvoltage-protection feature belongs specifically to the OVP version, not every unit carrying an EBL 119 label.

What supplies and charging profiles are specified?

The technical data, pages 9–10, states 230 V AC ±10%, 47–63 Hz, 1.9 A input, and up to 18 A house-battery charging current. The 1.9 A figure is mains current; it is not 12 V consumption. Actual charging current falls with charge stage, battery acceptance and thermal conditions.

The reviewed profiles cover six-cell gel and AGM batteries of at least 80 Ah. Gel uses a 14.4 V absorption stage and AGM 14.7 V, followed by 13.7 V float; the listed absorption durations are 16 and 4 hours respectively. Select the correct profile with the system isolated as the manual instructs. No lithium profile is documented by this revision.

How do the terminals and protection relate to the full unit?

The catalog's `out-pos` and `out-neg` refer to the house-battery charging connection. The complete installation diagram, page 15, shows 50 A protection at each battery positive for the full integrated system, which also carries distribution and alternator currents. That 50 A figure must not be read as 50 A charger output, nor transferred blindly to an isolated 18 A charging-only design. Use the full EBL and vehicle wiring instructions when connecting a real unit.

AC protective earth must be connected as part of the mains installation. Keep the mains and DC routes distinct and have the mains circuit and protection checked by a qualified installer. The terminal envelopes here are the documented 1.9 A input and 18 A charging limits, not the ratings of every EBL internal bus or connector.

What should commissioning and fault checks include?

Verify battery polarity, chemistry selection, fuse positions and the compatible control panel before energizing. Keep ventilation open: page 6 describes automatic current reduction when the unit overheats. If house charging fails, check incoming mains and reduce competing loads before concluding that the charger has failed. A starter-battery or alternator fault must be diagnosed using the omitted full-system paths, not this charging-only model. For long storage, follow the battery charging and cutoff sequence; operating the cutoff can release the heater's frost valve and drain water.

Build it out

Connect it to the rest of your system.

Add EBL 119 to your diagram, then connect your batteries, chargers and loads. Crimp calculates cable sizes and checks the connections as you draw.

Every cable you draw there is sized against ABYC E-11, from the same tables as the reference on this page.

Technical reference

Specifications, terminals and supporting parts.

Check the model, ratings and connection points against your own unit before choosing installation hardware.

Catalog specification

Nominal voltage: 12 V
Compatible systems: 12 V
Rated output: 18 A

Supporting parts

6.1 m total of 6 mm² (10 AWG) marine cable
Terminations for 6 mm² cable, matched to the equipment's screw terminals, leads or studs
25 A fuse and holder on the positive run
Heat-shrink, strain relief and terminal boots sized to the cable

Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.

Method & provenance

Where the specifications and sizing come from.

Manufacturer specifications describe the equipment. Crimp calculates cable results from the circuit and assumptions you enter.

From the maker

What the catalog says

Manufacturer, model, ratings and which terminal does what come from the catalog. A newer revision, or the nameplate on the unit in your hand, can say something different — when it does, the nameplate wins.

ABYC E-11

What Crimp worked out

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 run length and the current above are what drive the result. Crimp doesn't know how warm your space gets; draw the cable inside an engine-bay zone on the canvas and it sizes for the heat.
