hi guys, this isnt a DIY question but wanted to know what others thought as there seems to be some good sparks on here.
situation.....
company i work for had NICEIC contractors replace a 300mm 4 core swa cable(3phase Neutral, armour as earth). the cable was from a suppliers LV fuse cabinet in their substation. It runs about 10 metres into our main switch (a tpn switchfuse).Because a compatible spreader box wouldnt fit the space below the switchfuse they used a standard sheet steel enclosure. This enclosure has a removable gland plate into which they have terminated the swa gland. the gland plate has 12 small self taping screws holding it in place (not all are fitted correctly as the plate is bent slightly (tail wagging the dog and all that).
the banjo is on but not bolted through so obviously no earth tail is taken to the switchfuse or our MET. The Zs/Ze measurment is good (0.01 for what it is worth) but im concerned about the lack of earth tail from banjo. i was always taught with gland plates to take the earth from the banjo. they also havent removed any paint from around the gland or the banjo. system is TNS. basically im not happy with the works done.
im checking tomorrow to see if they issued a cert which they said they were going to. i have a feeling they will try and claim its our responsibility to do the earth or just claim the work is satisfactory.
going to have a look at regs later see which ones i think it contrevienes but i think maybe 543-02-07 to start with.
opinions please.
