Help with installation / diagram

Former Community Member
Former Community Member
Hi,


I am after some help with a heated windows installation / diagram - grateful for any input.

Unfortunately, the company supplying the installion went bust and I have been left with a system that doesn't  work (incorrectly designed).

We had a local electrician do the first fix wiring based on the diagrams but he says what has been sent won't work in it's current state and he doesn't have the relevant expertise to adjust it.

We live in a rural area and electricians are not that common especially for something as complex as this.

Rather than post up the diagrams and go into too much detail initially, I just wanted to know if this is a place to ask for advice and if not could anyone point me in the right direction. e.g contact details for an electrical engineer.


Thanks.

    Lack of CPC to windows is consistent with transformers being intended to make it SELV, but any voltage over 50 would break that.



    But could be a 'separated' LV system (like bathroom shaver sockets).


    OK where there's more than one item of current using equipment on a separated circuit BS 7671 would mutter about supervision by skilled or instructed persons and want unearthed protective conductors, but that's maybe not a real issue if there aren't any exposed-conductive-parts in the conventional sense - besides it might come more under appliance standards which often take a more pragmatic stance to some details than BS 7671.
