Thanks everyone, that has been very helpful. It all should give me a good background to start with.

I'm an electrician who is applying for a job where some knowledge of CAT 5 networking would be helpful, but not essential. I jst would like to get some tips, like how are the cores identified, and how they are normally terminated?

I have a digital heating programmer that is linked to a room thermostat, then to an electric boiler. The power comes into the programmer, then that feeds the thermostat, which then feeds to the boiler. The pum on the boiler is not switching over, so I was wanting to know how the programmer and...

It's a community centre, so all that should ever be left in sockets would be 13A plugs for minor accessories. I'm assuming that I'm linking in the contactor like I would the second half of a split load consumer unit?

I'm having to take on a project of installing a consumer unit, but the socket side has to be on a digital timer, so the sockets go off at night. I haven't found a digital timer of a high enough ampage to just wire in, so may have to use a 4 pole contactor. As I have never done one, can anyone...
