SA hasnt even caught onto RCBO's and the new rage mcb is the AFDD (arc fault detection device) ... with built in RCBO.

If you have rows of old 5 ft fittings ... an AFDD is a must ... I smelt a burning smell in my workshop last week ... but couldnt pin point wher ethe smell was coming from ... nex tthing there was a lot of sparks ...smoke a bang ... but nothing tripped ... it turns out one of the ballasts cooked ... quickly rewired and replaced all of them with LED lamps ... I must say the workshop doesnt look that much brighter ... I was expecting a huge improvement ...
