I'd use the 0R1 for most, 0R22 if you want a bit higher in some places, correct wattage is determined by P=I²R
You'll want them in all the conductors, not just the phase, and on every short bit of cableing that you want to appear a lot longer, so like between every socket on the ring final
Way to conenct them is to solder and then heatshrink, and then have all the sockets attached to a length of pvc trunking via a small piece of conduit and hide all the resisters in the trunking
It all sounds like a lot of work to me
The important part is to test for dead and practise the test sequence after nulling leads etc.
Having realistic values doesnt really matter, as long as you put the exact readings down on the form, even if it means 0.00 ohms.
