Locating an SWA fault?

[SJD]

Well I have tested continuity of each core, testing 2 cores in turn, 0.23 Ohm per any two cores for the approx. 65m length. And IR >1999 MOhm between any two cores. I just think the guy didn't bother to connect the armour, the customer has left a message for him asking why not.

Update: After some delay, the builder finally brought his electrician along and they replaced the damaged SWA section - the first approx. 8m, that goes under the concrete floor, and probably got damaged when laying the concrete.

There is a nice resin sealed joint to the rest of the cable. However, there is no continuity of the steel armour, only the 3 cores (which all test fine). Yes, I can earth the two halves of the SWA outer from each end separately, since one core will be earth. But should I really be insisting the joint is remade?

It's OK then, if you don't want more disruption. Earth it and test.

Sounds like some Electrical Trainee has done his first resin joint.

Get the builder to bring his sparky back again?

I think the guy has been around some time, probably not a Electrical Trainee, just has some odd ideas about regs. For example, he also said to the customer the SWA should be connected directly into a Henley block from the meter tails (all 65m of it), with no protective device.

this tale of electrical woe is chock full of fail.

of course you should connect the swa's together in the joint , thats what the spring clips and braiding are for.

of course you dont connect the swa direct to henley blocks , you use glands and a switch fuse.

these clowns should seriously step away from the work area lol.

Not actually an electrician then, just someone with a little knowledge "who's been doing it a long time". See it all the time...just because they haven't killed anyone yet, they think it makes them "experienced". pff

One things for sure be he a electrical trainee or not, ....he aint no electrician!!!

This forum is probably just a microcosm of what's occurring out there in the electrical world.
There seem to be quite few tales of Woe like this on here, scale it up to encompass the whole electrical activity in country...
I'll leave the rest to one's imagination!

You're absolutely right. See it nearly every job I visit. That's what makes it harder for us to do things properly, as all we hear is "well, it's worked ok like that for years..."
