    Free testing upon arrival. You are negative. You have been subjected to two different tests, using two completely different systems. You are healthy. You are free to go, and please spend alot of money here, so you can help to revive our devastated economy, and put some people back to work.

    If positive then what? Spend even more money in quarantine or will this be covered by the insurance scheme?

  2. It boils down to

    "We're not interested in pursuing tourists that work online.

    We are interested in pursuing people that attempt to live in Thailand on continuous tourist and visa-exempt entries."

    Simple - and common sense.

    ...from reading the comments it seems that common sense is not that common anymore. Or could it be that people with their common sense intact keep their mouth shut and stay under the radar?

  3. Just seen a few people post on fb that electric could be out for the next 2-5 weeks ! If they have to completely put new cables down , this could be the right timeframe

    Not too many companies worldwide that do this sort of operation. It was a Norwegian company that laid the two existing cables. That would mean shipping the cable from Norway possibly manufacturing it first, unless they happen to have 24Kms of the right cable stashed somewhere in Asia or the middle east. Then equipment has to be brought in, I would think from Singapore. All this assuming that the budget is available as this sort of job is kinda expensive.

    Maybe some experts can comment on this.

    First, I am not an expert. However, I have some knowledge from reading "Teknisk Ukeblad" (Technology Review Weekly) here in Norway which sometimes features HVDC cable manufacturing & projects. From that, I don't think anybody can buy 24 kms of submarine cable "off the shelf" - it is a high-tech product manufactured to order and I believe lead time is not anywhere near 2-5 weeks, and that is just for the manufacturing process... They can also be tricky to repair - your best bet is that the engineers will manage to do that successfully.

  4. I am an electrical engineer (since the days we still created circuit diagrams on blue-prints.)

    1. Grounding an electric water heater of the type they here is not really important and may be a waste of time, in spite of the dire warnings you read on these threads. (Yes, I know what the safety manual says.)

    2. BUT, using electric washing machine (where one actually touches the metallic inner drum after a cycle) is DEADLY without proper grounding.

    Do you see the difference? In the shower you must be touching/exposed to some metal conduit AND there has to be faulty circuit. Extremely unlikely. But it is important for the unit to have at least one (preferably two) cut-outs in case of a circuit fault.

    Most of the horror stories you hear about these water heaters are urban legend. In the real cases the victim grabbed/touched the metal pipe/nozzle of a unit that was incorrectly earthed. If it had not been earthed at all they would have been safer.

    Well, consider this: Your heater is properly grounded and there is a fault in the washing machine next door and you happen to take a shower as this machine is emptying to the same draining pipe as the shower is draining to. Then the deadly touch may be conducted trough the drain and to the ground through the perfectly good heater - the opposite way of what you might think. This can even happen with PVC pipes as deposits iniside them might conduct the current. Even if there is no heater in the shower this may pose a danger as the taps may be grounded and the drain become live...

    Example, in norwegian - "Neste" = "Next"
