It doesn't work like that.Just Want to source all the materials myself and install them before I get a spark in who is willing to check everything, connect the swa at both ends and pass it off. Not really mess with my house wiring.
In order to 'pass it off' - certify and notify - an electrician would need to verify each stage of the installation, so you need to employ one before you start and follow his instructions for what you might do yourself.
