I bought a new hob as we are fitting a new kitchen, we got all the other new appliances wired in, but the hob is a bit more complicated, it has 2 live wires then 1 negative and 1 earth, the wire coming out of the socket where it needs wired into where my old cooker was installed only has 1 live 1 negative and 1 earth..... I have rang around for an electrician but they all have a lot on for the next few weeks....... is this going to be as easy to install as the other appliances we wired in?
