10 ft one way
12 V system
Sized against ABYC E-11. The design current is the part's continuous draw. The length is one way; voltage drop includes an equal-length return.
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.
The example retains the specified 6 A fuse and sizes for the 5 A transmit load. Receive and standby use less current. Antenna, DSC identity, position input and optional data connections require their own commissioning checks. Manufacturer installation manual

GX1400GPS/E is a fixed marine VHF with internal GPS and digital selective calling. The advertised 25 W is transmitted radio-frequency power. The electrical table instead specifies 5 A during high-power transmission, 1 A low-power transmission, 1.2 A receiving at maximum audio and 0.3 A standby. The catalog uses the 5 A operating maximum for supply planning; daily energy depends on listening and talking time.
Connect the red lead to positive and black to negative, retaining the supplied 6 A fuse and holder. The nominal supply is 13.8 V, with the manual's specified tolerance; treat this as a 12 V installation. Use adequately sized extensions and protected, corrosion-resistant joints. Check voltage at the radio while transmitting, since a weak joint can work during standby and fail when current rises.
The canvas pair represents DC power only. An antenna connection, NMEA 0183 data wiring and external speaker connection are not battery terminals. The terminal limit is a protection-based planning bound rather than a separately tested connector rating. A replacement fuse should match the manual; repeated failure is a fault to investigate.
Locate the radio where its controls and distress cover remain accessible and the rear cable bends and heatsink have space. Test satellite reception in the intended position before cutting a flush-mount opening. Use a suitable marine VHF antenna and coaxial installation, following the manual's separation and exposure instructions. Do not transmit with the antenna disconnected.
The radio's data interface is NMEA 0183, not a Micro-C NMEA 2000 socket. When connecting a plotter, match transmit to receive, polarity, sentence support and baud rate using the manual's wire-color table. Do not confuse those small data conductors with the separate speaker pair.
Confirm the vessel's assigned MMSI before entering it and check the completed identity. Verify that the display has valid position and time, from its internal GPS or correctly configured external source. A powered radio with no usable position is an incomplete DSC installation.
Check normal reception and a permitted routine radio/DSC test, rather than testing the distress button. If the unit resets on transmit, start with supply voltage, fuse-holder contact and cable joints. Poor range with stable power points toward antenna placement, coaxial loss or a damaged connector. Record both a listening test and a transmit test; they stress different parts of the installation.

Build it out
Add GX1400GPS/E 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
Check the model, ratings and connection points against your own unit before choosing installation hardware.
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.
Catalog connection points, current direction and planning limits. Check the manufacturer's pinout and connector ratings before installation.

Method & provenance
Manufacturer specifications describe the equipment. Crimp calculates cable results from the circuit and assumptions you enter.
From the maker
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
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 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.
