We are busy drawing up plans to alter the house and build on. (I live in Cape Town) I see no reference to anything related to the electrical installation on the existing house plans.

I am at a bit of a loss to understand the workings of the municipality in relation to electrical plans - surely one would have to submit some form of diagram?

Please explain to me the process to plan the electrical installation (FROM A LEGAL PERSPECTIVE) - Surely one can't just slap a plug and a light wherever you want!
