Discuss Feeding a Shed Cu from the main CU in the Australia area at ElectriciansForums.net
looks good to me. i assume you are taking your cpc for the shed from the MET. if using steel conduit, it should be earthed.
How/where will the plastic conduit be run?
As for time delaying an RCD any s/o etc it protects must still be rated at 30mA in .4s so time delay the one in the house a then circuits within the house aren't protected in a satisfactory way.
Why would after splitting the mains, and installing a 100mA S type RCD to the tails to the shed, affect THE 30mA RCD's in the CU??
Just had a though about this, I was planning to put a 2 way CU in the shed with an RCD but just remembered that I can't have an RCD in the shed unless the main RCD is time delayed.
I take it that you don't have a load of steelwork in contact with the ground (it being a former 20ft lorry back) ?
at last.....someones asked what the earthing arrangements are here.....this will determine wether an s type RCD is required for discrimination purposes.....So you are taking a supply from an existing outbuilding to a massive aluminium structure in direct contact with earth? If so, is your tac room fed from a tncs supply from the house?
i can see this developing into an export..lol......And more importantly, is he going to be standing in a massive extraneous conductive part?
