The right Anderson plug mount is not simply the one with the most positions. Choose the smallest layout that handles the circuits you genuinely need, leaves room to grip each plug and allows the cables to bend safely behind the panel.
Quick guide
| Mount | Best for | Example layout |
|---|---|---|
| Single | One dedicated circuit or a tight mounting area | SOLAR IN |
| Double | Two related inputs or one input and one output | SOLAR IN + FRIDGE |
| Triple | Developed canopy systems with three distinct circuits | DCDC IN + SOLAR IN + AUX OUT |
Choose a single mount when the job is clear
A Single Anderson Plug Surface Mount suits a dedicated solar input, fridge outlet, battery connection or trailer feed. It is easier to position in a narrow panel and keeps the circuit purpose obvious.
Single does not mean temporary. For a simple system, one well-positioned and clearly labelled connector is better than a larger empty panel.
Choose a double mount for a practical pair
A Double Anderson Plug Surface Mount is useful when two circuits are commonly accessed together. Examples include:
- Solar input and fridge output
- Vehicle charging input and auxiliary output
- Two colour-keyed power circuits
- Primary circuit and a planned spare
Label the direction of power flow where confusion is possible. INPUT and OUTPUT are more informative than using two identical POWER labels.
Choose a triple mount when three circuits have a real purpose
A Triple Anderson Plug Surface Mount can organise a touring canopy with solar, fridge, charging, compressor or trailer connections. It also reduces the visual clutter of three separate bezels.
Triple mounts require more width and rear cable space. Check that three heavy cables can be routed without sharp bends or crowding.
Example layouts
Weekend touring canopy
- SOLAR IN
- FRIDGE
A double mount keeps the two most-used connections together.
Removable work canopy
- VEHICLE IN
- AUX OUT
- SPARE
A triple mount supports current needs and one documented future circuit.
DCDC canopy
- 3 POLE DCDC
- SOLAR IN
- FRIDGE
Use the purpose-designed 3 Pole + Twin Anderson Plug Surface Mount rather than trying to fit a specialised connector into a standard position.
Should you add a spare position?
A spare can be worthwhile if an upgrade is already likely and the cable route has been planned. An unused connector should not be energised without a purpose, label and suitable cover. If the future circuit is uncertain, leaving physical panel space may be better than installing a live spare.
Mixing connector sizes
AFS Offroad mounts can suit selected SB50, SB120, SB175 and SB350 combinations. Different connector families do not mate with one another. Select each position around the electrical design, then verify there is room for all contacts and cables.
Read the Anderson plug size comparison and the cable and contact guide before choosing the layout.
Custom combinations
A canopy often needs more than two-pole power connectors. The Build Your Own Surface Mount lets you combine selected Anderson and Deutsch positions. There are also dedicated layouts for three-pole DCDC and Starlink RJ45 connections.
Measure twice: front and rear
Check the visible panel width, but also check the connector bodies behind it. Leave room for:
- Cable bend radius
- Crimped contacts and heat shrink
- Strain relief and cable clamps
- Removal tools and servicing
- Dust-cover lanyards
- Finger clearance between plugs
Final checklist
- Every position has a clear present or planned purpose.
- Labels describe the circuit and direction.
- Connector sizes match the cables and loads.
- The panel has enough front and rear clearance.
- The location protects plugs from cargo and spray.
- The wiring design has suitable circuit protection.

Important safety information
Water protection: Dust covers, mounting gaskets and connector mounts discussed in this guide are not waterproof or watertight. Install them in a protected location away from direct spray, high-pressure water and immersion.
Electrical installation: All electrical wiring and installation must be carried out by a suitably qualified electrician or auto electrician, as appropriate. The installer must confirm cable sizing, terminations, fusing, circuit protection and suitability for the application.
