    Is this your house or a rental?

    It's my house.
    On the glowing lightbulb phenomenon, it comes and goes and seems to be related to humidity. I'm guessing a small leakage current. The LED bulbs only draw milli-amps so only a handful of micro-amps could make them glow.
    Electricians that switch the neutral should.....something nasty.....

    Can't Understand the same colour cable all over except for cutting Cost. Surely a decent Sparky would insist on Black for Hot and White for Cold (as they tend to call it here.) It is their own Interest in the First Place to know what is What. What on earth is anyone supposed to do if you have a problem and need to Trace. Obviously not Inspected and done as per Plan

    Without seeing your wiring setup. I can only speculate that the electrician that wired your house lost track of which wire was which. Mostly it is fixable. if all the lights on that breaker have the same problem then reversing the wires at the breaker panel will fix it.
    Since you own the house I don't blame you for not wanting to do the nail fix.
    I understand how you would want to fix it properly.

    All green wires through out. Must have gotten a deal on wire.
    The owner of the house is a high up guy in the City of Valencia and knows the city engineers.
    When my wife is cooking rice and the kids are taking a shower at the same time it blows the Circuit breaker for the kitchen.

    If you have a metal junction box (as opposed to plastic) seated in the concrete to hold your outlet in place, would this not do the same thing? I have often thought that I should just dig around in the concrete until I find a bit of rebar and ground the junction box to that rebar, then put a three prong outlet in the box, simply grounded to the box. But real electricians have told me not to do that without giving a reason.

    In Oz we have the 3-Pin Plugs with Earth, I have tried (Aussie) 2x PC's here via an adapter plug to plug into the 2-Pin outlet and both machines electrocute me when touching USB Cables or the metal casing of the machine when cleaning, not killer voltage but enough to make you jump if brushing against it, we have a Copper Pipe-Earth driven over a metre into the ground in our Garden which is watered everyday, I thought that would be enough to bleed away any wayward voltage, but I still get shocked every time I plug in the Cell Phones (trying several USB Cables to be sure it wasn't just the cable)
    I just assumed doing it on 2x PC's it was a common electrical thing here using the 2-Pin system... :cautious:

    It is illegal and very dangerous. You must run a green, grounding conductor and not use the neutral as your ground and it must go back to your ground bus in your panel. The neutral is considered "grounded" as it goes back to the source (transformer) and is purposely grounded at that point. If you used the neutral as a ground any metal device attached to that will carry some current; if your neutral opened between the receptacle and panel for some reason and you touched anything metal that was attached to "ground" you would now be the return, completing that circuit.

    Any other "ground" you try may bleed static off but will not work for any fault current as it needs to go to the source (where your grounded and grounding conductors are bonded together). The easiest thing for these residential systems is to drive a ground rod at your panel, put in a ground bus and bond the neutral and ground together at this point, and this point only. Then run another conductor from the panel to your receptacle and put in a grounded receptacle. Most of these houses run either PVC or PVC flex so you should be able to run a grounding conductor in the existing conduit. Worse case you may need to pull out the existing wire (attach a pull string) and pull a new hot, neutral and ground.

    Here are a couple simple examples. The second example is a standard US, 120/240 2 phase system; the Philippines uses 240 phase to neutral with one phase, couldn't find an example for that but the concept for grounding is the same.
