I have just moved. Currently there is awful white trunking everywhere, I want to channel the wiring into the walls. I have bought black Round Conduit and the Size is 20mm x 3m and gang boxes to sink into the walls is there any thing I need to be take into consideration?
There is a consumer unit fitted.
All I want to do is channel out the brick work and sink the conduit into the walls after feeding it through it. Some advice would be nice.
