General Information
The Arc detection unit will recognise serial, parallel and ground arc faults in both radial and ring circuits. (Note serial faults in a ring circuit does not always lead to an arc fault due to power flowing to either side of the fault at the same potential voltage.
These units must be switched off when conducting insulation testing to avoid damage to the AFDD
The AFDD should be tested every month by pushing the Test button.
Recommended terminal screw torque 2Nm
