How to wire a mains voltage electric window opener or openers to automate your windows – Step 2

Step 2 –

Talking to your electrician about the cabling

  1. As a rule, mains voltage actuators have a 3-core fly lead which is directly wired into the actuator body. The length of this fly lead will depend on the electric window opener you have chosen, but it is usually between 1 & 1.5 mtrs long.  These fly leads are designed to be wired into a junction box by your window.
  2. Typically, the 3-core cable will consist of a permanent neutral & 2 switched lives (most electric window openers are double insulated so don’t require an earth) but this isn’t always the case so please talk to us.
  3. Your electrician will need to Install a fused spur to protect the circuit.
  4. They will need to run a cable from the fused spur to the switch / controller position then on to the electric window opener(s) (call us to discuss your control options)
  5. At this stage, you need to consider the position of your controller, if you are using a single gang switch or temperature control panel for example this would need to be at standard switch height, or if you have a remote receiver panel this could be either by your windows, hidden in a cupboard or even in a loft space.
  6. Electric window openers are wired in Parallel, see example below.
