Where do I connect the earth from the underfloor heating ?

 

To ensure that the underfloor heating is fully earthed, the earth wire from the heater(s) must be connected to the earth wire from the main supply.

Connect the earth using a connector or the earth connector fitted on the electrical back box.

The underfloor heating system must be protected by a 30mA RCD at all times.
