[QUOTE="Duane B, post: 434405, member: 27137"] AFDD "Ark Fault Detection" mcb breaker. Do we really need this . the ones I've seen are double the size of an mcb. rcbo. so would take up 2 ways for one mcb, breaker Afdd system, Arc fault detection devices are extremely sensitive and designed to sense and respond only to potentially dangerous arcs. They use a special algorithm to distinguish between dangerous and working arcs – i.e. the harmless sparks that you see when you flick a switch or pull a plug. This is important as over-sensitive AFDDs could be prone to nuisance tripping – e.g. interrupting a circuit when it senses the slightest harmless arc Suppose 18th edition is gearing up for metal clad boards with a full rack of these in it. more outlay for sparks and a new book to go with it [/QUOTE]
