I’ve seen debate in the past on here about whether to earth both ends of SWA at the glands even when using 3 core with a core as the cpc. My question is:
If I gland the load end and earth the banjo there, then gland the supply end but run the 3 cores straight through the building skin so there are no terminations (obviously us Using the SWA inner sheath and mounted in a Wiska box), should I then run a fly lead from that gland through the building to the inside fcu?
As it stands, I have good r1+r2 readings and a good Zs (0.59) my earth fault path runs along the SWA armour to the earthed gland and then returns back via the central cpc cable.
To earth the other gland I would either need to make a larger hole in the building to make room for a fly lead, or cut the cable at the junction box so can add an earth - the way I see it is that I would then create an unnecessary break and additional joints in the cable.
Anyone got any views on this? Thanks
