But you don't want the SWA armour connecting to the remote CU since you then don't have a local earth
either made as a tt with earth rod or run a minimum of 10mm 3 core swa across to shed as in post one and you can use the armoured connected both ends and just bond the services going in to the building with 10mm cable which will be far better than a tt supply in shed. I have a 25mm 3 core supply in to my garage and use 1 core for the earth and house is pmeI'd terminate the swa in a plastic enclosure below the cu
didn't chuck a couple of gallons of water over it did you get the readings down for the test wernt the towers metal and in to the ground concreted in with rebar and use that as the groundTry getting good readings on Dartmoor had to put earth mats down to get good earths on a couple of radio towers
