[QUOTE="Doc Hudson, post: 484068, member: 1607"] So to summarise:- By not doing comprehensive testing to start with, you wasted time and money purchasing replacement RCD, only to find the fault was not cured. For the sake of others reading this thread I must make it clear that It is very easy to test if an RCD is operating correctly within its prescribed limits for compliance with BS7671. (NOTE: testing is done with loads DISCONNECTED). If the RCD is operating within its specification, then the fault is elsewhere. And if more than one circuit is supplied from an RCD it can be argued that this does not comply with BS7671 (reg 314.1). Multiple circuits via a single RCD immediately suggests checking for cumulative leakage if an RCD trips unexpectedly. Doc H. [/QUOTE]
