norman Posted July 24, 2020 Share Posted July 24, 2020 I agree with PJ but as a subby I would leave a spare pair twisted together in the device if available. Nothing is foolproof to a sufficiently talented fool.

sixwheeledbeast Posted July 24, 2020 Share Posted July 24, 2020 Testing with a DMM with resistors in place is not going show useful values IMO. Resistors wrong way round you should be finding with normal walk testing as part of the other commissioning procedures. Likelyhood of this is much lower with built in resistors becoming pretty standard. Staple through a cable would fault on EOL and if DP the value wouldn't seem correct for the cable length and again you would be closed or tampered so would find that on a walk test. When everything was DP having the devices contact resistance was useful but with EOL and built in its pointless for reference in the future.
