That sounds like good advice and definitely worth knowing about. Thanks.
People in the States have no idea what unreliable electrical grids are like. When it rains hard, and for a length of time the electric poles that are in the middle of a rice field, (rotting from being constantly in water), will topple over. Then the power is out for hours while they replace the pole. Fortunately lately they have been using metal or concrete polls for a replacement.
