    Control of lights at Xmas time

    Every year when the clocks got back (well maybe a little while after) it's time to start thinking about those lights that are going to cover the front and rear of the house, and for some a lot more.

    My puzzle is that most if not all of these lights come with pre-moulded plugs. This implies that I have to use a standard mains sockets, but I believe that I cannot connect this to a webbrick as technically it cannot switch 13amp (i.e. the socket rating).

    Any ideas?

    Cheers,

    Ian.

    I don't know about the regulations side of things, but since it's clearly going to draw far, far less than 13amp, just cut the plug off and connect it up to the triacs of the WebBrick Controller, and it'll work fine!

    problem is, the plugs are also the transformers. so if i cut the plug i loose the 24v transformer. not sure is webrick can sink to provide the 24v, but if it can surely there will be a cable length problem due to higher current?

    So you'll need to preserve the transformer, by plugging it into a trailing socket, then connect up the trailing socket to the webbick. Since the power taken by the transformer is small, there won't be a problem.

     You can make use of the relays on the web brick, and if the voltage is under 24v you could also use the open collectors to switch the negative.

     

    If it ain't broke, fix it until it is

    (advice from me is just that, advice)

    Great ideas, thanks guys.

    I feel a few webbrick controlled 2amp round pin sockets being floated around the house.
