To start with the distribution circuit may take MAXIMUM of 1 second to trip (it may even be higher then that but I cant check at the moment), you...
That paragraph alone shows you have little to no understanding of either the regulations or how RCD's work.. going by other posts related to TT...
What is your understanding of that type of RCD Spin?
Indeed you can get some nice long trip times of them :)
Because if you dont fit a 100mA S RCD at the mains you wont achieve the discrimination required from the 30mA RCD in the submain board.
I do..
Indeed there are, but only a couple will be right... that load on 50m of 6mm is a bit wimpy... for 90% of the time volt drop isnt an issue so...
Why would you want to "set it to 1s" ? There is no need. A 100mA S RCD is all that is needed to protect the submain feed..
Its slightly more complicated then simply deciding if you need TD RCD's or not.. The deciding factor will be how are the sub main feeds being...
If you cant exchange it for what ever reason your going to need [IMG] and possibly [IMG] What ever you do don't try connecting your sander...
Same as Sinewave, I only use Click accessories (they look similair to MK ones) very good quality at a good price 2 gang double pole switched...
As seneca said, nothing wrong with that cabling..
Even allowing diversity on the cooker its still over 60A, Besides the two showers should be rated at 100% so its over the limit regardless....
That is effectively what that switch is, although it has an "off" position as well
