Installing Automatic Caravan Steps - 12V Wiring and Safety

Installing Automatic Caravan Steps - 12V Wiring and Safety


Automatic steps add convenience but require correct 12V wiring, fusing, and weatherproof connections. Follow the manufacturer’s instructions closely.

Electrical Basics

  • Dedicated fused feed from your caravan distribution panel or auxiliary battery.
  • Correct cable gauge for the run length and peak current.
  • Quality earth - return to the system negative/bus, not thin sheet metal.


Control Options

  • Door switch - deploy on open, retract on close.
  • Manual rocker - driver control when a door trigger isn’t desired.
  • Ignition interlock (optional) - inhibits deployment while moving.


Install Steps

  1. Mount the step to reinforced points as per manual.
  2. Route wiring in split conduit away from moving parts and exhaust heat.
  3. Seal connections with heat-shrink and weatherproof grommets.
  4. Function test - deploy/retract multiple times; confirm automatic stop and obstruction clearance.


Safety Notes

  • Warn users to stand clear during movement.
  • Fit a visible LED courtesy light if supplied; fuse per spec.
  • 240V work must be performed by a licensed electrician.


Bottom line
Good wiring and waterproof terminations are the difference between trouble-free operation and intermittent faults.
