It has often been said that unwanted tripping of an RCD can be caused by earth leakage currents produced by electrical equipment, for example power supply smoothing circuits.
With the growing use of electrical appliances in our modern world, and the requirements for additional protection against electric shock by use of an RCD introduced in the 17th Edition, is there an increased likely hood of unwanted tripping?
In this video partnered by Megger Instruments, Dave Austin "Tests the Theory" that nuisance tripping of RCDs is likely due to the functional earth currents generated by modern electrical equipment. Dave visits a domestic installation taking measurements form different electrical appliances, explores the sensitivity of RCDs, and provides incite to this interesting topic.
