1. As neutral is connected to the earth in the home fuse box, I don't see where any improved safety exists.

 

2. As my solar inverter monitors current exiting on live matches current returning on neutral, and detects a fault and switches off before any other device detects fault. I don't see where any improved safety exists.

 

Same for electrical trunking,

Cables in plastic trunking carry 30% less current than cables in air. My walls are poured concrete, the only flammable materials in the walls is the plastic safety trunking. I'd prefer the 30% more current safety factor.

My earths go to earth rods.......

So I should have my entire house rewired?

Easier to return at no cost to me, and a refund on the item.

Has a neighbor got an earthed system? Plug it in there and see if it works as it should. Alternatively. can you earth the socket to the steel work?

Tell me about it, the list is getting longer whilst I'm stuck here in sunny (and dusty) Egypt earning the $$$ to pay for the jobs.

 

EDIT - Please do not fall off the roof!!

Yep it never ends

The third pin for the Schuko Plug is missing, usual it's a threaded one you screw into the thread above the fixed two pins.

Absolutely not! Schuko plug has two pins and the earth is on the metal contacts on each side of the plug. The hole in the plug is not treaded and meant for the countries that have the earth as an extra pin in the wall socket, like Russia. 

Thanks for all the helpful suggestions guys.

Now charging using the 16a charger the car came with.

Engine cover off, fan blowing so the silver box in the middle doesn't overheat and fail. A little Chinese design fault....... DOH!

Neutral and Earth (PE) are connected AT THE ENTRANCE POINT of the fuse box BEFORE it goes to the main fuse.

Afterwards the PE is completley separated to Neutral.

 

If you don't understand why - let a professional do the job.

That's what he said. 🙂

No room for condescending remarks, this is a help forum. Just scemantics thinks I.

It's possible your new socket has the live and neutral swapped over. Check with neon screwdriver.

 

Get a 1.5 or so meter rebar and pound it in the ground and clamp an 8 or 10 gauge copper wire on it. Rig a diy three prong pigtail power cord with the ground wire spliced in connected with the wire from the ground, you can use an extension power strip as well, just splice in the ground to the power strip. If you have the materials there, it shouldn’t take but a few minutes and it will get you by until you get it done properly.

I understood this a bit different...

"1. As neutral is connected to the earth in the home fuse box, I don't see where any improved safety exists."

 

If the PE is missing in his installation (sockets) I have a small doubt if safety is given.

 

Sorry. I guess I just have to ignore this forum from now on.

I'll repeat,

 

When the main breaker is on earth and neutral are essentially the same.

 

Having two wires connected to the same bar in the fusebox provides no extra safety that I can see.

 

But irrelevant as they sold a product with a plug that doesn't fit in Thai sockets, which is probably more dangerous.

Almost all EV chargers test for the presence of ground. The check is quite easily bypassed for those who like to hack but most definitely not a good idea.

 

Besides the obvious safety reasons, grounding is extremely important for efficient operation of suppression and filter devices within the external charging device and vehicles onboard charger.

 

Schuko plugs

 

In Thailand its quite common to find products fitted with Euro style plugs. This is often the result of production run limitation not including all plug types. There is little chance of Thai consumer protection preventing this practice so best cut off and fit correct plug if ground is required.

Most 3rd party granny chargers don’t test for ground connection.

 

If you have live and neutral reversed, you will get a ground fault to prevent electrocution as the charger will spoof an earth by connecting ground to neutral internally.

 

As I said before, check live and neutral reversed in your socket.

I removed my incoming earth and displayed a ground fault. Bit difficult to read the red writing.

Yours looks like a wall box, they always use a proper earth.  And do test for its presence.

This is a classic example of where a little knowledge can be dangerous.

 

1. Having MEN bonding in the 'home fuse box' doesn't mean that you don't need to provide a ground wire FROM the power outlets TO the home fuse box.

 

2. Your solar inverter configuration has nothing to do with your EV charging configuration.

 

The energy saving of wires in trunking versus wires stapled to the wall is irrelevant here.

You'd think all the kitchen appliances would need Thai 3 pin plugs if that were essential for safety. But they either have moulded 2 pin plugs, or schuko plugs that don't connect to earth in Thailand 3 pin sockets. So not really much point in running earth wires to sockets, as they almost never connect to the appliances.

 

Almost no appliances in Thailand connect to earth pins in Thai home sockets.

 

My home only has one socket with a connected earth wire, and that's the EV charger the electrician installed last weekend.

Fixed it, bought a different granny charger for 1,500bht.

Works perfectly without any earth wires connected, and saved me 700bht.

Charges perfectly at 8a, the only odd thing being the display is in Russian.
