Cooker connection point

[ARW]

Can anyone spot any problems?

[Dave Liquorice]

<apprentice> Nothing wrong at all, but someone's made the cable with the colours in the wrong order. </apprentice>

[ARW]

It is connected to something.........

[Fredxx]

I thought the clamp was for cable exiting the connector?

Some illiterate person to fail to associate the earth symbol, L and N with the appropriate conductor?

I hadn't seen the "N (earth sign) L" labels embossed in the "bakelite", but my first thought on seeing the photo was "I think I'd have put earth in the middle so a stray live or neutral wire would be more likely to touch the earth in the middle rather than touching live to neutral. I suppose it doesn't matter *too* much as long as the lead from the cooker to the connection point is connected with matching wire colours, even if the neutral terminal has been used for the earth, but it is very unconventional and a definite "fail" if an electrician inspected it!

[Roger Hayter]

I'm not sure what the two wires connected to the earth screw on the back box come from, unless the back cable's earth wire gets to the main terminal via the screw. I suppose that wouldn't be totally wrong, but odd.

[Jimk]

Earth not connected?

[Jimk]

Oh yes! Under the tile gob there's an "N" with the attached earth wire etc!...

[John Rumm]

Well ignoring the whole "all the right wires, just in the wrong order bit", I kind of get the feeling they have missed the whole point of having the cable clamp in there...

Hmmm, now shall we clamp the lose dangly wire drooping off to the cooker, or shall we do the nice feed wire that is buried in masonry, and hence sure to accidentally get pulled!

[John Rumm]

...and those stray bits of expanded metal lath romping off in the direction of what ought to be the live terminal don't inspire confidence either!

[Brian Gaff (Sofa]

Perhaps a blind person such as I did it? I think I'll demand tactile cables in future. grin. Brian

[Fredxx]

Perhaps leaky gloves for a sensation when you touch live?

[ARW]

That is correct and one of the errors.

And what are the consequences of doing this?

Hint - a LN reversal would not actually be a problem as long as the cooker cable colours matched the colours in the outlet but this is not a LN reversal.

To avoid any confusion the 6mm earth is terminated to the back box earth lug and a fly lead is taken to the outlet plate. It's not the way I would do it but it is allowed.

[ARW]

You are close but missing something fundamental about the earth terminal on a cooker outlet plate...

When you say it does not matter too much you are wrong (although a LN reversal on a outlet plate would not cause a problem).

[ARW]

VBG

[Roger Hayter]

Is the earth terminal bolted to the metal plate, then?

[ARW]

Yes and you win.

That is a LE short circuit in the photo.

[Jimk]

Who was it?

[Roger Hayter]

You did give us a big clue!

[Fredxx]

I'm confused, not difficult I know.

The earth terminal has a live conductor fitted. I can't see any earth wire going to neutral cable.

I can see an incoming earth and neutral behind the foreground cables but little else to help.
