Thanks. The bootlaces do make a neat build. You should see my wire markings?LOL. Wrap-around thermal labels, on all the wires. My thinking here was, should I need to move something from Non-essential to Essential load, I would need to move the neutral and earth too, as each is seperated. This way, I don't need to search for wires.
 
To be quite honest, I'm not concerned over a momentary feed-in or spike. What I want, is should the grid go down for any reason, I want the disconnection to be made.
Also, I imagine, should any compliance be required later, I seriously doubt that anyone will be able to confirm that the this unit would not fulfill the requirement of an ANTI-ISLANDING device. 
And on the point of tripping the pre-paid meter. I am lead to believe that on my meter, the feature to shut down on reverse power detection, is disabled.
I think, if legislation requires a device to prevent REVERSE POWER FLOW, then at +-R2000, this unit should fulfill the requirement. The way I understand this issue, there are 2 clear terminologies that are used? REVERSE POWER FLOW DETECTION, and ANTI-ISLANDING. Reverse power flow detection/prevention, should react to prevent the electricity meter from seeing this as an attack, and Anti-Islanding is isolation from the grid, to protect maintenance workers from electrocution?
Lets see some opinions?
