    You definatly need an electrician for this as after the change everything will need to be tested and certified using the proper equipment. Post your location and someone maybe near by to help you out Tim

    Lost neutral

    Hi biff, The rcbos were installed with the new db (the one with the dodgy tails) in the refurb a year ago. I guessed it would be returning through the earth, but what if it is not a tncs system? (just trying to cover all bases untill i know more about the job) What would cause the voltage to...

    Earth bonding to gas and water supply - help!

    A person doesnt have to crawl in with the cables, they can be pulled in using rods, but as theres laminate and tiles its unlikly it will be a useable route. External is the way to go, it will be cheaper and cause less destruction. Tim

    Earth bonding to gas and water supply - help!

    Unfortunatly you cant compare your house with the bloke down the road. The regs have changed since 2005 (17th edition 2008) and bonding requirements have changed. Bonding MUST be up to scratch before any electrical work can be completed. Check out this from the esc...

    Nightmare

    Why not strip out the internals of the db and use it as a jb for your crimps, then mount your new one below it. Then you dont have to mess around with the endless amount of conduits Tim
