hi - i've got a mixture of pendant and spotlights upstairs in my house. I just replaced the ceiling rose for pendant light and accidentally left one of three earth wires loose. Everything worked fine initially then I realised the spotlights will not turning on in other rooms in the house upstairs. I checked my handiwork and realised one of the three earth wires had come loose, I put it back in position and now that light and another pendant light in a different bedroom works but none of the spotlights upstairs (landing and bathroom) work. Could I have blown all the transformers with my earthing error? Baffled and frustrated! Please help if you can, thanks
