How about this https://www.lazada.co.th/products/3-positions-on-off-on-changeover-control-rotary-cam-switch-20a-i5426917678-s23049633097.html You may need to DIY a handle so Madam can operate it.

Merry Thingy and a Happy New Wotsit to you and yours @MJCM The controllers "might" have on-off terminals, have you got the manuals or at least piccies?? Do you need to change-over when the pumps are operating??

Did I mis-read the OP? The gift of Maggi!

With one or three women persons?

Switching DC can be problematic, I suspect that the simple knife switch is going to be the "best" solution. Generally, you can switch DC with an AC rated switch if you stay below 10% of the AC rated voltage, so your 600V knife switch is just about there. There are rotary switches that should do the trick, if you can find 600V (or DC rated) ones, but they tend to be pretty tight to turn 😞 How about using a couple of DC solid-state relays wired to a small toggle switch, easy to operate, easy enough for a competent DIYer to implement? Are there any solar controllers in the mix or are the pumps wired direct to the panels? Of course, more panels would mean you don't need to switch anything 🙂

@OneMoreFarang Some photos of your stands would be appreciated, others may wish to DIY their own 🙂

And where is he planning on concealing it? I believe they are x-raying all arriving baggage before it gets to the carousel, but that's about it unless you get selected to have your bags x-rayed at the customs post on the way out.

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??
