Spot what's wrong

[Redvanman]

For the eagle eyed out there, can you tell me whats wrong with this arrangement and for a bonus point what reg. no. would apply.

The only bit of info you need is that its a TT system.

 

[Bobster]

Rcbo ...

 

[Flanders]

Neutral not switched

 

[trev]

How many points are available?

 

[Redvanman]

Neutral not switched

Spot on.

Idiot who installed it obviously threw the link away because it comes in the single phase kit.

Any answers on the regs. no.

I will tell you in a bit what else they done wrong and how much they charged.

 

[Redvanman]

How many points are available?

1st 10 points went to Flanders, the bonus 10 are up for grabs.

 

[benji]

looks like some grommet strip needed round that hole

 

[Fox]

No CPC sleeving on SWA armour
No cable protection where they've drilled through the back of the distribution board

 

[tony mc]

Does that bare stranded cable link the N to the E by any chance now a DIY TNC-S ?

 

[Flanders]

Got The BG book out now so working on the REG, It there an upfront RCD on the installation ?

 

[Redvanman]

Both valid points and that's just some of the problems.

PS It isnt a SWA armour its the old unsleeved earth conductor

 

[Redvanman]

Does that bare stranded cable link the N to the E by any chance now a DIY TNC-S ?

Nope but this is a NIC approved firms install

 

[Redvanman]

Got The BG book out now so working on the REG, It there an upfront RCD on the installation ?

Nope but should be as the grommet strip is missing. Tails were tight on casing.

 

[Bobster]

A lot of faults with this. Aside from the RCBO and what's already been mentioned, there's another fairly obvious mistake.

Would that be no circuit ID ?
Or something else.

 

[Bobster]

Something else, circuit ID may be present on the cover, although I tend to fit core IDs as well.

 

[tony mc]

Would it be that all the L1 & L2 MBC's would be useless !

 

[Bobster]

No there's a single phase link kit fitted, you can see it just above the main switch

 

[sparkdog]

Its a metal cased cu on a TT system.

 

[Pete999]

Has he got the N cable in the wrong terminal at the intake? can't quite make it out eyesight going, or the Diazipan is blurring my vision

 

[telectrix]

RCD on the tails then.

 

[Bobster]

The OP has got a list of faults, I'll wait until he posts it up to see if he's got it.

 

[jaypp]

..............

 

[jay sean]

No RCBO for ring final ccts

 

[Pete999]

TT system No RCD???????, post 24 can't see any Ring Final circuits marked, only saying

 

[Redvanman]

Sorry had you go do a job.

Right the list of problems I noted were and you cant see most of then:

No neutral link between main switch and neutral bar therefore only single pole isolation on a TT system.
No grommet/ bush/gland for incoming tails therefore a RCD required as main switch or before board. If glanded correctly then RCD not needed as the meter is below
All lighting circuits have no cpc with metal switches and lights in use. Even through the cable entering the board has cpc. Under the board theres a piece of 2x2 plastic trunking stuffed full of the old cables all thro crimped to extend into new board. The old cable has no cpc but new cable does.
No testing was done before or after the install.
No labels except RCD warning (I no some of you dont like labels but its in the book)
No circuit chart

Someone made a note re ring circuits but all circuits do have RCBO's but in picture you cant see the left hand side fully.

Take a stab at how much he was charged and any thoughts on the reg no yet.

 

[Bobster]

You've missed some

 

[Redvanman]

You've missed some

Go on tell me

 

[davesparks]

Ferrules!

No cover over the ends of the bussbar.

No additional protection to the tails in metal DB

 

[davesparks]

And it looks like the neutral may be squished under the screw rather than between the plate and the moving 'cage' bit.
