A Split Load Consumer Unit is also known as High Integrity Consumer Unit which contains both RCDs and RCBOs. the Neutral wire should be connected through Neutral Terminal (The symbol N is printed on the RCD nameplate to identify the Neutral terminal. RCBO & Arc fault protection is recommended in the 18th Edition 2018. Wylex have no miss busbar connections and quick release technology built into their circuit. To control the ON/OFF operation of the electrical appliances, an SP or DP switchescan be used in the sub circuits and final sub circuits. A consumer unit is a type of distribution board (a component of an electrical power system within which an electrical power feed provides supply to subsidiary circuits). Left one may be correct, but it's too short, the red loop of wire is not acceptable. To connect a single phase 230V AC load circuit to the newly installed garage consumer unit, keep in mind that the Live should be taken from the output terminals of MCB and Neutral and Earth from the Neutral & Earth Busbar terminals in the CU respectively. The CU never tripped and it and the MCB's are not overloaded. It protects electrical appliances from damage and more importantly, human beings from electrical shock.

These cables are called tails, and in this instance, with this type of unit, are 16mm cables. It is also an offence to interfere with the seals on the electricity meter. Split load consumer unit is the combination of RCBO Residual Current Breaker with Over-Current, RCD Residual Current Device and MCB Miniature Circuit Breaker. The box pictured top-right is a "Wylex standard" fitted with rewirable fuses. In a combination of RCD + RCBO distribution board or single phase 230V split load consumer unit, the load circuits should be connected via three wires i.e. As they must sense the current in both the line and neutral, they have connections for both. The load points and circuits on the RCD + MCB side can be connected via three wires i.e. Disconnect the power supply (and make sure it is really switched OFF) before servicing, repairing or installing electrical equipment. They are suitable for smaller properties with less complex circuits and are available in a number of 'ways', depending on the manufacturer: Hager: 6 way (VML733H), 10 way (VML755), 12 way (VML766), 16 way (VML716) This example has a flying lead for the incoming neutral connection and a standard terminal for the line busbar.
