One way of failing electricity is to switch off the tubelights and the fans by using the dial of a wrist watch. The reason is as follows:
Sun = 19 21 14 = 54
current = 3 21 18 18 5 14 20 = 99
and 99 - 54 = 45 (i.e. reflecting the sun)
watch = 23 1 20 3 8 = 55 (one more than the sun =54)
So try switching off the fans and tubelight switches with the wrist watch dial. You may just end up shutting down the power.
