The absence of a neutral line creates an issue where the test button would be supplied by the full concatenate voltage (typically ~400v), which could damage the circuit. The above image diagram is just an example and rcd is available in many shapes and.

3 phase distribution board wiring diagram pdf wiring diagram is a simplified tolerable pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the aptitude and signal contacts amongst the devices. If there is no neutral at all, the rcd will be connected normally but a bridging resistor will need to be added. You can use a 4 pole rcd but you need to look at the wiring diagram on the side to see whether the test button is connected to two of the phases or between a phase and neutral, in the latter if there is no neutral present then a resistor (value depending on the test button circuit) connected between one of the phases and neutral terminal will ensure the test button works,.

In brief, your diagram looks ok to me. In this single phase home supply wiring diagram, the main supply (single phase live (red wire) and neutral (black wire) comes from the secondary of the transformer (3 phase 4 wire (star) system) to the single phase energy meter (note that single phase supply is 230v ac and 120v ac in us).
