Should all RCBOs in a CU/DB be Bi directional and Dual Pole

Should all RCBOs in a CU/DB be Bi directional and Dual Pole, I am mainly talking domestic dwellings but it may also apply to commercial and industrial

The RCBO have electronics which expect the current to flow the correct way

Increased amount of properties with Solar PV, Battery storage/Car To Grid thus back feeding

The increased reporting of Pen faults in street potentially reverse feeding a property via the Earth/CPC

What role the supply characterises have eg TT, TN/TNC/TNCS, IT

  • I’m not sure it would help a broken PEN conductor anyway , for solar they should be and other small scale generation systems.

    it should be decided on a case by case basis
