I've looked at the installation instructions and they do not specify if the peak supply can be provided by
a) the existing ring
b) or it has to be a new ring
c) or if it has to be radially wired the way the off peak has to be wired.
The instructions state that both supplies need double pole isolators so is there a nice compact device to do this and the cable outlets in a single box designed for the job or must I use two switches and dymo labels to say which is which.
This is why talking/emailing with someone who has done the job will be so much easier.
