SWA cables - fly leading armour as cpc??

[westward10]

In the past where it was required to several cables I fitted a copper bar across the lot, down the side of the board to the earth bolt and a link to the earth bar.

i always take 3/4 strands of steel into the cpc connection aswell, what if the gland gets loosened off and some doughnut doesnt put it back on correctly?

How are you doing that and following manufacturers instructions in using the glands?

Also i'm reading that as 3 to 4 stands rather than 3 quarters. In which case, will do nothing anyway.

Aside from this, have you ever seen a properly terminated SWA gland just loosen on it's own?

If I saw this practice on one of my jobs I'm afraid I would insist on having it remade.

How do you manage to do that elsparko? just curious

 

[elsparko]

easy, just dont cut through 3/4 of the strands of steel, bring them in through the gland, rest glanded as normal, i was taught to do this by a guy who done mainly industrial, i said if someone loosened it off and removed it , then reglanded it without the steel strands it would at least still have some connection to earth.

and yes i mean 3 or 4 not 3 quarters! lol

i should add that it still has a frying pan and flying lead, aswell as the 3 or 4 strands, and a dedicated cpc.

worst case scenario i still want there to be some earthing to the steel wire

Yes agree Bob, with respect "elsparko" not really something I would ever do. Don't think that would comply with the Regulations. On a par with snipping a few strands from a conductor to get in into the terminal. IMO.

It's a poor way of doing it an unfortunately as you've now no longer got evenly applied pressure all the way round the gland seat, it's actually more likely to come loose with vibration.

It would compromise the IP rating of certain glands also.

just what i was taught to do, if its not right id rather be corrected than carry on doing it wrong, which regulation out of interest?, do you guys just gland the steel, frying pan either side of fitting, then drill through, bolt the 2 frying pans together, then flying lead from inner frying pan?

i do all the above, just taking in a few strands also, my first boss was insisted on these strands being taken into the cpc, incase someone removed the entire gland then put it back in just hanging there, there would still at least be some protection on the steel wire

we worked mainly on farms, so maybe industrial was the wrong word to use, but same kit, seen plenty of farmers have a go at reglanding and it just sits there hanging by the connections, gland about 3 inches from unit

but as i said if taking these 3 or 4 strands is wrong id rather not be wasting my time with it either lol
