If an AFDD costs £200 how much for circuit protection when installing a 48 way 3 phase DB that does not supply any 3 phase circuits or crane lifting magnets?
As they only work on sustained arc faults not sparking faults or I squared R heating faults, and we know it is hard to strike and maintain a sustained arc at 230V why are these devices require?
