Pardon me, This Was regarding your notes about "limit of knowledge", you admitted that you would do not want to change your opinion regardless if there will be conflicting information coming from more qualified electrician, so this mean you where ashamed to admit limit of your own knowledge (potentially) . And yet you are asking others to be shameless in this regardI don't understand what you mean, sorry.
Anyway, I've given my opinion. Hopefully you can move on with a suitable sparky who will design, install and test a suitable solution.
