[QUOTE="jack2017, post: 445439, member: 29002"] Ok - then thanks to all for the replies. this link [URL="https://www.youtube.com/watch?v=5XST0DkotYw"]Armoured cable clip [/URL] (which appears to be one of the best) says about 60 seconds from the end: 1, ...must always connect armour even if internal ground is used (my expansion - 3 core single phase) 2. ...generally ground at both ends 3. ...but there are occasions to just connect one end (my expansion - no explanation given for that) Point 3 is - again - left dangling. I must say I'm surprised at the lack of certainty here but I'll connect both ends as I install because I can always cut it out easier than adding it later if I find any complete explanation somewhere. I don't foresee an issue with that on this short run to a pump anyway. I've just finished a dry run of gland fitting. Everything went fine (cables I've done - just not armoured) with just one small hitch - worth noting perhaps: I hadn't quite scored some of the strands of armour enough to make them snap off easy. so I twisted them a bit more to snap them - this left the tips bent slightly making it very difficult to get the pressure ring in place. I'll know better next time. thanks jack [/QUOTE]
