I found out my girlfriend's house in Isan did not have a ELB or Safe-T-Cut, so on this trip up we purchased an ABB consumer unit with MCB and RCCD (the price was only a little more for the consumer unit plus Main CB, RCCD, and MCB than a Safe-T-Cut device).

We are running a hot water heater, air con, computer equipment (with 22 in monitor), tv, fridge, etc.

The sales woman said, and I've read on this this board and others that this setup is equivalent to using a Safe-T-Cut device.

Anyway, now I'm in Isan, and am trying to set this thing up...the gf, says her brother-in-law and uncle are qualified enough to install it, and the sales lady of the consumer unit says it is semi idiot proof to install, and of course I'm watching over their back.

The diagram I am following is



the consumer unit looks like


Does this setup look correct? The electrical lines going to the appliances have 2 wires inside, the live one will be the one connected directly to the Mini Circuit Breakers, but where does the other line connect? In the picture I've circled in blue where I, and the technician in the store said the other line to the appliances (the neutral line) will connect, can someone just verify this is correct. The official digram does not seem to indicate where the other wire connecting to the appliances should connect

Also, what size wires should I use for the internal connections within the consumer unit, I assume the larger the better since inside the unit can be transfer lots of power, but I couldn't find anywhere it recommended a size.

Lastly, is copper the only recommend grounding method? The brother-in-law says he has some non-copper, iron (i think) stick that could be used as a ground. How deep into the ground should this be?

Okay, thank you very much for your help, maybe I'm being too cautious, but I think I need to be with electricity in Isan. Thanks again for your help.
