[QUOTE="Phoenix, post: 543855, member: 8133"] If its a plastic cassed isolator, then whoever fitted it, ought to have fitted a link to the earth terminal off the banjo tag [URL]https://www.electricpoint.com/media/catalog/product/cache/d4899413b50b1a3a0f3f4e7fe5351c12/e/a/earth-tag-25mm-brass-spare-banjos-for-swa-gland-kits.jpg[/URL] or they might have used an earthing nut [URL]https://uk.rs-online.com/web/p/earth-protection-accessories/7000818[/URL] If its a metal clad isolator, then while the same is still good practice, you might also find it with just a banjo tag bolted to the case (which forms the earth path), you might even find it with just the paint scraped off under the gland (which is ok as long as its a decent job), there might also be some out there with no earth continuity because the paint hasn't been scraped off! Post a picture and we will tell you what has been done and if it looks right or not [/QUOTE]
