A lawyer named “Strange” was shopping for a tombstone. After he had made his selection, the stonecutter asked him what inscription he would like on it. “Here lies an honest man and a lawyer,” responded the lawyer. “Sorry, but I can't do that,” replied the stonecutter “In this state, it's against the law to bury two people in the same grave. However, I could put ‘Here lies an honest lawyer.'” “But that won't let people know who it is,” protested the lawyer. “It most certainly will,” retorted the stonecutter “People will read it and exclaim, ‘That's Strange!' “

It is 100% correct and almost identical to your box. But note, it is wired as TNC-S (MEN) you would be TNS so the incoming neutral would NOT go via the ground bar, just directly to the bottom of the main breaker. The incoming supply goes to the bottom of the big breaker. The live from that breaker goes to the live bus bar that the MCB clip on to. The neutral from the main breaker is connected internally to the neutral bus bar to the left. You can actually see the internal connection going to the right in the middle of the neutral bar.

Sort of. If the system is TNC-S (MEN) there is a link between the INCOMING neutral (that is before the main switch) and the earth bar. But the bus bars are not actually connected together. This arrangement is important if an RCBO incomer is used as linking after the incomer will mean the RCBO will not operate correctly (at all). Our OP is in a condo which is likely TNS with a separate earth running right back to the transformer where the N and E are connected together and to an earth mat. If it's an older building then the N-E link might be at the bus-bars on each floor. Just how it's done varies. This is how TNC-S (MEN) is implemented in Thailand. Note the routing of the incoming neutral via the earth bar. Diagram is from this PEA document Groundwire Mk2 book-Manual.pdf my translations.

Personally, I would get one of your friends over to survey the installation and document exactly what is awry. Then, either fix it on the QT, or go to the juristic with your documented survey and ask if they have a certified electrician they can recommend. That said, if it was done by their certified sparks ...

From your report it IS an incinerator I never leave the toaster unattended anyway, the timer can be erratic and either result in merely warm bread or crispy-critter!

I have no beef with the ones you show, they are intended for wires up to 4mm2. The smaller ones are good to 2.5mm2.

Is this your home or a rental?? If a rental get the landlord to sort it!

Get one of them in to have a look. And then ask them to fix it if they don't run away screaming!!

He was probably wearing boxing-gloves too.

Sorry. without being there I really can't say what is going on. WIRE COLOURS MEAN NOTHING!!!!! For all we know he's used brown for earth. Do you have any test gear (a simple multimeter would do)? A neon screwdriver would also be handy. Seriously, you need to get a man in before someone dies or a conflagration starts. Try talking to your local PEA/MEA office, many of their chaps are not averse to a bit of moonlighting and they are likely to be decently competent.

As a Brit I would use Wago connectors. Failing those, wire nuts (not permitted in the UK)

A complete mess! If you are getting shocks, time to turn off at the mains and get a competent sparks in!!!!!!!!! Is there a ground rod anywhere? Where is it connected to??

Wire colours mean nothing! You won't (ok shouldn't) get shocks from the neutral, but if you install an RCBO with the box as it appears to be wired then it won't stay switched on. But I see a lot of grey wires on what is supposed to be the ground bar, and green/yellow wires on what is supposed to be the neutral. Working out exactly what is going on is nigh on impossible from a photo, you need to be hands-on with some basic test gear. The only way to be certain is to disconnect everything, and with the power off of course buzz-out (meter, bulb and battery) the neutrals from each circuit. Whilst you are at it those taped joints have to go!!! Particularly the one connecting a brown and blue (what did I say about wire colours).

This ^^^ BUT!!! The bar to the left of the incoming breaker should be the NEUTRAL. The bar at the top which is bolted to the case should be the EARTH/GROUND. Wire sizes need to be checked. I also note that there is no earth-leakage protection (as a minimum an RCBO incoming breaker), this is a vital safety feature. IMHO It's a total mess, I recommend getting a competent sparks in and re doing the whole shebang (with emphasis on the "bang")!

Happy birthday to James Burke (remember Connections?), the man responsible for the most perfectly timed shot in television history! Definitely no Take-2!!! https://en.wikipedia.org/wiki/James_Burke_(science_historian) AQOG9CCuij1kEAXbOqYCSQ88k5BY17qobC2khY2CLG3BLmJRGyLGwg7D_9DdzX3Wf_6Nd3MzWG8DQMPz_dRDJbgr.mp4

POTY really lost its appeal when the software was updated to prevent people from changing their votes 😞 I do note that other fora have polls where the vote can be changed, I wonder if there's an option on the Invision software. Have to check with Admin.

Does it have a manual "pop-up" button? Does it work? Have you emptied the crumb-tray? Checked that the mechanism isn't obstructed by an errant bit of bread?
