I've got one of those Hanabishi electric pans. It comes with a two pin plug (not earthed). The manual says the pan should be earthed by connecting a wire from a screw on the bottom of the pan to a nail in the wall. That sounds a bit primitive to me and I've read elsewhere that this is an inadequate means of earthing.

Fortunately the circuits in my flat are completely earthed. Can I just run an earth wire from the nearest socket, leaving this exposed near to where the pan is used, and hooking up the pan to the earth wire each time it is used? I'm just presuming that would be a more effective way of earthing than the nail-in-wall approach. Or is there any potential problem doing it that way?

connect an earth wire from a convenient point on the pan with sufficient cable to reach a power outlet and connect the wire to the earth point on a 3 pin plug - plug it into the power outlet and presto - -,,​earthed.

Perhaps be easier to just replace the two pin plug as above and run a ground wire to the three pin replacement plug - always grounded and no need to attach/detach anything. You can make it neat with cable ties to the original two wire cord.

Is it a "Suko" (spelling) type plug which is a 2 pin plug with earth points on the plug edge?

Thanks for these ideas. Would have taken me a long time to hit on this. Both will work, though I guess wiring into one 3-pin plug will be neater.

It is a flat type 2-pin plug, not the German type - no earth points on it - so I'm going to have to get a 3 pin for this. One slight problem: I've yet to find a 3-pin Thai plug that can be DIY wired internally (like British plugs). I suppose that means I'll have to cut a plug off something else and splice the wires with tape...

You can find 3 pin plugs if you look hard enough...

They are quite ugly though.

3 pin with or without pilot light are available

Assume the cable has no ground in it so you would also need to run a ground wire to connection on the pan and the 3-pin plug.

And another listed at HomePro

Thanks for the suggestions. I think Artisi's plug is the winner there. I've never seen this at HomePro though - and it's not on their website. Any idea where to get one?

3 core cable is available at some places

HomePro /Global House. I bought many at HP - they have 2 pin 3 pin with or without pilot light.

Assume the cable has no ground in it so you would also need to run a ground wire to connection on the pan and the 3-pin plug.

That's right, so the idea is to have the 2-core cable that came with the pan + a separate earth wire attached to the bottom of the pan, bound together for neatness and feeding into one 3-pin plug.

You mean open the pan up and connect the wires inside, bypassing the socket on the side of the pan where the current cable plugs in? Hmmm, not sure I fancy that challenge.

Cheers, will seek it out.

There is no need to open pan - just use the normal ground screw and run the wire from that along the outside of the normal zip cord to plug.

Also available at Tesco Lotus if that's more convenient.

We also have a unit like you. Until your post, I never looked at it, but sure enough there is a "ground" screw underneath. I have never done anything to ground it. My wife uses it a lot and there has never been a problem. Are they class-2? If so, don't need the ground. Just wondering if anybody know for that?

Problem is when an earth fault arises you would not be aware of it if you are dead.

There's no problem if class-2 b/c no fault would happen.

That is not 100% true - double insulated can fail - it just requires more than one fault - all it would take is a pin going through both layers of insulation. Class 2 is no guarantee and I would never trust on a metal chassis. In this case there is a ground point installed and I am sure there is a valid reason for it being there.

A bit like all the water heaters connected without any earth, the reason given not to earth is "because they have RCBO or similar installed" but the manufacturer's normally have at least on sticker attached saying " this requires earthing - but I suppose Thai electricity is different so it's ok.

It's definitely not Class 2. This thing surely needs to be earthed. The whole outer cover is metal, and there is always water sloshing about when cooking.

The design of this product is just barmy - presumably it dates back to the 1950s. The earth wire is in effect permanently attached to the bottom of the pan - the nut is tiny and not something you can easily undo with your fingers every time. It's not clear how we are supposed to wash the pan with the wire attached. Not sure why Hanabishi can't just put an earthed plug on it...

Okay, I found the Haco plug at Tesco Lotus, 58 baht. This is good. Love the transparent cover so you can see what's going on inside.

This is what it now looks like. It's safely earthed, but I'm now trying to think of a way to make the earth wire easily detachable for washing and for storage.

Alligator clip?

Yeah! That'll do it.

Spiral wrap (any computer cable store will have)

Google automotive spade connector - comes in male and female configuration - push in pull out - solves your quick un/connection problem

That would work

Put this on pot

And this on ground wire of cord

Design of this type of appliance is to put it mildly - bloody stupid. So primitive with a 2 lead cable and a separate earth point - I would never buy anything with this style of power input as a matter of principle. Of course if you have a standard Thai 2 wire power system (no earth) when go ahead and use -- 'cause you know Thai electricity is different.

Oh ho ho. If your wife likes suki-yaki or however you call it, then you, or she, WILL buy such a unit.
