Vehicle Electrical Requirements 
Brake Controller

 

All MDC campers and caravans require an electric brake controller to be fitted to the tow vehicle by law. There is 
a wide range of controllers available that are suitable.

 

                  

                  

 

Correct Vehicle Wiring for MDC Caravans

 

To comply with national laws on breakaway systems, you must supply a maintenance charge to the 
battery/batteries that power the system should it be activated. In all MDC products, the breakaway is powered by 
the house batteries in the caravan. For this purpose and Anderson plug connection is fitted to all MDC caravans 
on the drawbar. Your vehicle will need to be fitted with a power supply to a 50 amp Anderson plug near the 
towbar so the trailer can be connected. The vehicle only needs to supply power while it is running so a voltage 
sensitive relay or switching device may be used to protect the start battery when the car engine is stopped.
