Picture of the week.

Well its that time again folks!

Breif history:

Extention / loft conversion to a bungalow. Original sparkie went AWOL. He had replaced the consumer unit, but left this under the floorboards below the consumer unit / intake.

The 1.5mm² SWA feeds a fairly well loaded 6 way CU in the garage. The joint box is fed in 2.5mm² fed from the 32A socket MCB. The armouring is no longer earthed either.

He left a huge list of other problems, but this was the most shocking.

this was the most shocking.

You would hope not wouldn't you

You say he went AWOL - perhaps this was temporary as he had run out of galv boxes that day? (Still no excuse leaving this live though)

And I dont see the need to cut the wires from the fuses like that - having to re-strip all those cores (unless this was a full rewire job)

Have a look at my topic in electrics outside of UK.

Any other "good" pics from that spark's work?

 

[C&GStudent]

WOW!!

Perhaps I'm being naive but I'm amazed people do stuff like that.

What was the approximate load on the 1.5mm SWA?

 

[RF Lighting]

The load was not massive. A couple of lights and 6 or 8 twin sockets, but not much used in there at the moment.

This is planned to be a workshop in the future though.

 

[C&GStudent]

Hypothetically, if there was a fault on the cable with say 20A running through it. Would it actually catch fire without the MCB tripping?

 

[RF Lighting]

Depending on the load on the rest of the ring, yes.

If most of the appliances in the house were off then >30A could flow in the cable without the MCB tripping.

It would have to be a L-N fault as the cable was RCD protected.

Cheers RF.

The armouring is no longer earthed either.

I guess the gland at the other end was not in contact with the cpc?

Can I?

 

[RF Lighting]

Can I?

No you can't

Don't know TBH, as I am putting in a new 6.0mm² feed to the garage, and rewiring it. I haven't really had a proper look yet, but I expect there may be more photos to follow.

The SWA is glanged straight into in insulated CU so I suspect the armour is not connected at that end either

 

[securespark]

Can I?

No you can't

Cheers!
