## Questions & Answers

**Q: Is this ok for switching between 2 different 240v supplies up to 10 amps in a camper van**
A: I’ve not fitted it yet, but I’m using the one I’ve purchased for that purpose. Incoming 240v mains supply or 240v from inverter on to the camper can system.

**Q: Using as a camper hook up to invertor where will the earth go please, do we use a seperate wago or something**
A: Yes, just connect all earths into a Wago connector or similar. Space is tight inside this enclosure. Also, be sure to buzz out connections and switching prior to wiring, the identification of the terminals is not overly clear.
