ᐅ Electrical cable "torn apart" – what should I do?

Hello,

the drain and water connection have finally been installed in our kitchen. During the floor penetration, an existing electrical cable was accidentally punctured. The sheath and insulation are damaged.

Unfortunately, the floor structure is already finished, and all tiles are laid except for the open spot for the drain.

The electrician tested the cable and said it is still functioning. However, he would recommend replacing it anyway. Repairing or using a junction box is not an option due to limited space.

The plumber said he would cover the costs.

The problem is that we would then need to have the tiler come back, who currently has no availability, and we are under time pressure.

At the moment, it is only wrapped with insulating tape.

I have not yet asked the electrician if there is a plan B. This cable powers a triple outlet in the kitchen worktop area.

Is there any way to repair it, or how would you proceed?

Best regards, Jan

@Gartenfreund: So now the conduit and cable would be defective?! Unless everything is laid in Stapa tubing ;-)

@TE: It also looks to me like a small junction box could still fit in there (approx. 4 x 8 x 4 cm (1.5 x 3 x 1.5 inches))
I would reconnect the cable inside there. That would be an alternative to relaying it.

Correct.
But as I understand it, the ground will now have to be opened to replace the cable. This involves a considerable amount of work. It also includes retiling the affected area. This could have been avoided with a conduit. That means less dirt and a faster process. Cable out, coupling over the conduit, new cable in, and done.

I don’t think installing a junction box in the floor is a good idea.

Okay, that’s true. However, pulling a cable through the corrugated conduit afterward doesn’t always work.
I would still prefer a small junction box or, even better, a splice enclosure. The latter is also compliant with VDE standards.

Yes, that’s how I would do it too... just buy a coupling, possibly fill it with casting resin, and done...
