"This is a very versatile CU. The Neutral and Earth Bus Bars are modular and can be located in a number of positions along a top rail by means of simple clips.
The benefit of this is if you are replacing an older CU where you are limited by the lengths of the existing wires. By moving the bus bars around you can replicate the locations of the old CU neutral and earth bars.
RCD trip well and a good variety/size of MCBs (i.e high current devices and in type C)."
