Answer Posted / pillay
ELCB is voltage based sensing device.If the leakage voltage is above 40 v(usually) it will trip.
RCCB is current based sensing devise. If the leakage current is above the stated amount it will trip.(U CAN BUY DIFFERENT VALUES from 5 milliamps to 300 milliamps)
RCCB has a higher level of safety because even if the leakage current did not get to the earth by the normal circuit maybe because the earth wire was not connected or loose but passed through somebody and than to the ground the rccb will still trip if the current is above the milliamp rating.

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?
