Re-wire

[bigash]

Doing some rewiring on behalf of an unnamed council.

This is what I found today when removing the lid off of surface mounted trunking.

Has anyone ever seen this before where the insulation is removed to get around corners?

I really dont like the cable going up the side of the door frame inside the arco.

I know this is a no no but found it strange that the circuit would of passed testing as surely an insulation test would of failed. Maybe the wiser ones on here could enlighten me.

I hope the photos have attached spam ad free.

Looks pretty badly bodged to me.

I don't see how an insulation test would of failed though to be honest. Should of been picked up on inspection in the IV though i reckon.

I have just thought about that and yes it may of not showed up on the insulation test.

Its crazy as the damaged cable was in the same room as the main fuse board. There was plenty of other surprises that took this two day rewire into a one day rewire. as we could not leave the circuit in the state it was, so overtime in and a very late finish.

The words Hazard came to mind when i discovered it among other things.

Never seen that before, although I've only ever worked in a house with T&E twice.

What I can say is it's RAF

Go on then, prey tell

RAF = Rough As F***


Bend radius is to sharp for that size cable.
CPC/earth needs identifying sleeving.
As for the door frame, that is RAF.

Right OK

 

[bigash]

The idiot that done the original rewire is really RAF.

I am amazed by what you find in council houses. Today's find was a light pendent attached to an old light pendent that had been hidden between the ceiling and floor boards and an old junction box that to be honest was worse than RAF it was bloody ridiculous.

The main thing I am learning here is how not to do things.

Looks like 10mm2 in MT2 to me? Cant tell from the pic whether the CPC is stranded or solid though to be honest.

Certainly ambitious either way.

Its stranded mate and 2.5 t & e.

LOL I've been working as an electricians mate in social housing.
You see some sights, that's for sure

Can't say i have ever seen a harmonised colours 2.5mm2 T&E cable with a stranded CPC! But then again i did a job the other week which was wired in white twin and earth, except the CPC was insulated as well throughout the cable.

First time i have come across this type of cable.



FT&E CPC sizes

1.0mm2 = 1.0mm2 CPC
1.5mm2 = 1.0mm2 CPC
2.5mm2 = 1.5mm2 CPC
4.0mm2 = 1.5mm2 CPC
6.0mm2 = 2.5mm2 CPC
10mm2 = 4.0mm2 CPC
16mm2 = 6.0mm2 CPC

 

[bigash]

Omg thinking about it neither have I.

Now this is where I backtrack and say maybe I need to get the caliper out and actually measure the cable instead of stating size by eye and a s***e memory.
Also in one of the photos there is a 2.5 t&e in one of the photos.

 

[davesparks]

That ain't no 2.5! My bet would be 6mm minimum

With a stranded CPC?


My bet is still 10mm2.
