At the risk of becoming another David 'RCD' Strachan(topic here), There appears to be another issue the 17th is going to raise.
From what I have read, TT Low Voltage installations will now require 0.2 disconnection times for ALL final circuits, other than those exceeding 32A or distribution circuits which are allowed to be 1 second.
Given that in TT installs the standard has been to put sockets on a 30ma RCD on the sockets, and lighting, cooker etc on a 100ma Time Delayed RCD ensure both compliant trip times AND discrimination, what will we be expected to do under the 17th?
Are they likely to produce shorter time delayed RCDs that do come under the 200ms rule (will they still discriminate?). Or will we see boards with multiple RCD Banks separately fed from one isolater, including say a 100ma RCD for lights etc (except for those in bathrooms which will have to be on 30ma anyway I believe).
I do hope they are quickly planning to produce an updated on site guide that will will clear up some of the issues that still seem to be in the air about the 17th - it is not that long until July. Am I the only one that thinks more guidance is needed from the 'experts' who wrote it and expect us poor sods to work to it.
Would it be too cynical to suggest that they left out clear guidance so that they can rake in more profit from us by selling us all the extra books that will appear.
Of course I could have missed something - the only chance I've had recently to read the new regs (and watch the lovely NICEIC DVD!) has been in bed which is not the best time to take everything in....
