Best way to fix this mess

[Alwayslearning22]

 Hey guys I need some help if you can

What’s the best way to repair this hole around the cable in meter box? I think they used a hammer to make there hole. 
 

thanks

Trim the white plastic to be tidy. Mix some self levelling compound and pour in. Have a cup of tea/coffe

self leveling will work on a plastic meter box?

A sparky might comment but I think the blue and brown wires need more protection - like trunking.

Why would it go in a plastic box, isn't the repair to the concrete floor? If they were hitting the plastic box with hammer there wouldn't be a plastic box in the photo

A bit of silicone and a wet finger?

[Roundtuit]

Does it need repairing?  What do you want to achieve?

If rats or mice get up the hockey stick pipe beside it  they could enter the cavity?

I've zero idea of what I'm looking at. Is the cable regular twin and earth (T&E), as it appears to me to be so.

 

If it is, then it's a dangerous install. This needs to be in "containment", so as @Mr Punter suggests it needs conduit or trunking.

 

Even if this is temporary it is dogshit on toast, and the bread was out of date.

What have I told you about drinking during the day?

That's non setting electrical putty

My previous house looked like this too 

seems to be the standard around here

Yes appears to be. Is that not right? I have solar panels. Has that anything to do with it 

[sgt_woulds]

@alwayslearning22  is this the finished install or did you take the photo when the Sparky was till working on it?

 

Has it been left with the cover missing on the box above?

 

If this is the case, then as well as the single insulated tails it has left live terminals exposed and the cables connected to the unit above are dangling from the terminals rather than being mechanically supported by a gland.

 

This is all kind of wrong!

[sgt_woulds]

For some reason I cannot zoom into the photo.  Also, it would be good to have a shot from further back showing the whole installation.

It's to de-rate the outgoing supply, so L > SP MCB > final destination.

 

The cable feeding the MCB should be able to take the current of the supply so it's not looking up to par.

I don't think I'd be sticking a wet finger anywhere near that installation 🙄

Having single PVC’s ‘on display’ is a no no. How the feck are they getting away with this if it’s the finished article!?!

You should have seen what I came across recently when installing a heat pump. My electrician (who was the first electrician my customer had ever known to actually check in the meter box even though they'd had a lot of building work and re-wiring done) found that the armoured cable installed during previous extension work going from the meter box through loft and into the CU was undersized for 100A supply. Then he found that the armoured cable hadn't been made off correctly and the tails were single insulated, squeezed against the metal gland. The sparky who had installed it had then taken some spare insulation slit down one side and wrapped it around the single insulated tails to make it look like they were double insulated. Stunningly bad and the customer said the previous electrician apparently had a good local reputation......

…..for his carpentry work.

@SimonD @Nickfromwales

 

I have seen similar poor installed wiring.

What is the best way around this?

Can a flexible sheath be used?

How would the ends be terminated around the existing wires?
