Project builder and electrical/cbus Guys, We are just about to sign the paperwork/contracts for our home to be constructed by a project builder(Clarendon homes). this builder 's electrical contractor only does Hills automation. We really like the design and price but the fact that I want to use c-bus is a problem. it is a 2 story 45sqm house so pre-wiring for c-bus is a must before the gyprock goes in. I'm thinking to pay for structured wiring from the builder and then try and meet with the sparkie and get him to run the cbus control cable in at the same time to all the switch points. I'm also wanting to run 4 runs of cat5/6 plus coax to every room. I have done 2 years of an electrical apprenticeship and could easily do it all myself but the builder is saying that I am not allowed onsite to do anything. what is the best way to approach this situation ? anybody had experience with this ? should I be just getting another contractor to do the whole of the electrical system instead ? we are in Sydneys west.
