A sizing result with its assumptions attached.
There is no standalone feed to size here: this part either has no positive current-carrying terminal or declares no continuous draw or rated output of its own, so a lone cable number would really be its terminal rating. Its cables are sized by the circuits they serve — use the terminal map and the complete-system fit check.
The part the engine actually sees.
Terminal map
| Terminal | Polarity | Direction | Rating |
|---|---|---|---|
| BATT − | negative | input | 500 A |
| LOAD − | negative | output | 500 A |
| B+ sense | signal | bidi | 1 A |
| AUX sense | signal | bidi | 1 A |
What belongs around it.
- Terminations matched to each catalog terminal
- Strain relief and terminal protection for the installation
- Connection hardware selected from the complete system topology

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.
