Lesson two: secondary control switches TrailLite

This article and videos explain how to use your water heater, isolation switch and main power switch

The following isolation switches are all located in the upper kitchen cupboard. Above is the main switch and below are the white isolation switches:

• External PowerPoint (if you have one)
• Charge (your external electric socket to connect to mains)
• Fridge
• Hot Water Cylinder

These are mainly used for tradespeople servicing your appliances. Please don't leave these on (unless one is damaged or there is danger with having a certain appliance live).

Instructions for Main, Inverter and Isolation switch

Instructions for Invertor

  • If your motorhome has an Inverter you will see a black on/off switch for the Inverter 


  • Use this dial to turn the power supply system from MAINS to OFF to INVERTER.
  • Only have the power supply system dial only on INVERTER if you need to draw 230V when you are not plugged into mains.
  • As soon as you are done, change the system back onto MAINS. This avoids drawing power from your batteries instead of mains when you are next plugged in. 20200428_111412-1
