My Thai son's house, plans clearly marked for a 3 phase connection in the kitchen (electric oven and 4 point electric cook top).
House completed, development company 'inspector' signs that all items on the plan have been satisfactorily completed, electrics mentioned.
Son buys package of kitchen appliances, seller sends 'qualified technician* to install all the appliances.
*Turns out he is a Thai gualified elctrician.
Technician tells son that the outlet in the kitchen (in fact all outlets in the kitchen) are basic wiring; there is no 3 phase.
Son calls development company, office girl tell son 'oh that's not allowed in Thailand'. Son demands a meeting with a senior person from the development company.
Now there's a list of excuses/reasons why 3 phase not fitted, but very little concern.
Son demands an answer as to when 3 phase will be fiited and a guarantee that there will be no extra charges. Takes weeks and daily push from son to get it completed. Development company now claims that it's illegal to bring other technicians/electricians on site to confirm there is 3 phase and it has been installed correctly and safely.
Son refuses to make final payment for the house and land and tells dev. company he has put the whole situation in the hands of his well known lawyer.
Suddenly a call from snr. mngr. of the dev. company inviting son to quickly bring a licensed/qualified electrician on site and full cooperation for this person to check all the wiring.
Small additional point, It's now discovered there's 2 power outlets fitted in other ooms that are not connected to any wiring. Word spreads, other owners now demanding further checks on the electrics fitted in their houses, and some work done to fix problems exposed.
