Question about earth wire - photo attached

[James1234]

An electrician noticed that the clamp on the earth wire in my house wasn't right while he was fixing an unrelated fault. He called the power company because they have a legal duty to fix it. I noticed that the guys from the power company have used tape instead of a clamp and wondered if this is acceptable?

Thanks.

I suspect they've just put the tape on to help protect the joint.

If it's been done properly it will have been sweated on to the lead sheath of the cable.

There could well be a clamp under the tape or as above it's been sweated on

I would ask the spark to come back and check the Ze ........

Also....get that earthing conductor checked pronto! Earth fault current will be unsure where to go and won't know it is allowed to flow through it as it's splendid green/yellow markings have been painted over in emulsion.

If it had been sweated on i think the paint would have burned off the cable

They use a special sprung clamp now that won't loosen if the lead creeps and also doesn't cause any unnecessary lead exposure to the jointers. We had the same done and the earth was a lot better afterwards.

It's not a wire it's a tape, should have gone to Spec Savers

A cv spring.

A cv spring.

Does that comply?

 

[telectrix]

better than a bed spring.

Don't actually know but are supplied in some jointing kits. I don't reckon there is one under there it is too bulky on one side. Wouldn't mind a pic from a couple of other angles.

Could the bulk be where the braid has been folded over to prevent it from being pulled out?

Possibly would like to see what is below that tape.

Used them in jointing kits and they seem ok, but that doesn't look they've scraped the crap off to make a good connection, i'd certainly investigate

Are they not a CP clip? as in "constant pressure"?
As mentioned,i think they were in part designed,to remove some of the risk/skill from a proper sweating job.

But i have seen everything from jubilee clips to a child's tool bench vice,used...

Yes basically, CV joint is actually constant (angular) velocity which is a special kind of universal joint that is basically smooth regardless of the angle or turn, used in car driveshafts

 

[Chris1234]

The tape is just holding the cable in place while the superglue dries.

 

[westward10]

One of these they come in various sizes.

Constant force spring

...And as a little extra,the balls out of a CV joint,make devastating ammo,for a high-powered catapult

It looks bulky enough for a spring clamp under the tape although I tend to use self amalgamating tape over the spring.
