Right ... Just been nudged to set this up by Paul.M and sounds a good idea following recent threads I've done in the Arms..

Rules....No Offensive material... edit if required before posting as this is the public arena.
Anything to do with the trade or in and around it ...H&S pic's welcome.



I've posted this a few times and this is at a mates house following a kitchen refirb several yrs ago. mg_smile:

This is in a small precinct car park. Consumer unit and contactor enclosure replaced, aside from being a lash up there are no cpcs from the dist board. Zs at lighting columns 16.33 ohm.View attachment 60376

to say that that was as rough as a badger's arse would be insulting to badgers.

 

[Dustydazzler]

That is rough and some , plain old rough as you like...proper Badgers

I would be ashamed to leave an installation in that state

I also hate those copper busbars that Saddle underneath the neutral , but that is more manufacturer Roughness than installer roughness...

I have no idea why they need to do that. The main switch could have the L on the inside, next to the MCB, then the busbar doesn't need to go round behind the N connection.
Probably some legacy arrangement for incomer arrangements. Maybe I'll ask Schneider, do you think they'll know the answer?

 

[Simon47]

My WAG would be that their main switches have L on the right (because that's what a previous product needed), so L has to be on the right. Now, it's not worth the extra cost having two versions of the main switch - and they decided that it would be cheaper to just include the saddle in the busbar. It's not just a case of changing the printing - it's another SKU to manage right through the supply chain. And you can guarantee that some sparky would need a new main switch and have the wrong one in his van - with the obvious result that someone ends up with a wrongly labelled main switch.
Now sits back and waits for someone to point out that their catalogue already holds a "L on left" main switch

Even though it was old a few years back at least everything was earthed, this was an upgrade

 

[Simon47]

Just as a thought ...
When people come across stuff like this, do you ever report it as dangerous ? The lack of CPCs in that bodge surely warrants a report to HSE ?
Even if the bodger didn't put their name to it, the responsible person in charge of the car park would be responsible for having employed a competent electrician - it would fall on the RP to identify the sparky concerned even if said sparky didn't put his name on it and has since gone on an extended holiday to incommunicado.
But I guess after a few years the sparky would just claim "it was OK when I left it, someone must have nicked the CPCs to weigh them in"

They are all two core bar the one with the yellow conductor which was a cpc, it now floats on a block connector within the contactor enclosure.

Trunking just behind a gas hob
And when it was changed to gas, connections were just cut, the 45A switch was on when I arrived, live conductors millimetres from the metal oven housing.

Edit... don’t worry though, this happened before a 2017 satisfactory condition report which didn’t pick it up ?

I've never seen contactors for anything but a DOL what are there purpose?

Control circuits, say you wanted a 6a rated light switch to turn on 40A worth of lighting.

 

[davesparks]

Contactors are used where you don't want, or can't have, the full load running through a switch, or when multiple circuits need to be switched by a single device.

Contactors allow a low current switch to control a much bigger load.

Contactors are also used to make remote switching easier by avoiding significant volt drop in the switch cable.

Thanks, makes sense makes me think of electronics and Relays etc.

Just another word for a relay.... although contractors are combined relays.... to switch so many poles through one switch.
Also can use a 12v momentary push button to switch and hold in a 400v 3 phase load (like a motor) or as described above, a simple light switch turning on a much higher load than the switch itself could handle

I didn't want to go totally off-topic just been trying to get a better understanding of DOL and there always wired in such a way that there latched providing undervoltage protection totally forgot really there just like relays and do what relays do, also never seen them used for anything but DOLs.
Doh..

 

[westward10]

The control circuit for the contactors is a dawn to dusk sensor so when the lighting level drops it switches the contactors on.
