As per IE regulations pertaining to wiring installations, the load on each power sub-circuit should be normally restricted to ______.

  • A.5000 W
  • B.2000 W
  • C.1500 W
  • D.3000 W

Answer: D

The Indian wiring rules limit the load on a power sub-circuit so that its wires and its protective device are not overloaded. The key gives the limit as 3000 W for each power sub-circuit, option (D). The lower values of 2000 W and 1500 W are more suitable for lighting sub-circuits, and 5000 W is above the limit the key gives for a sub-circuit. The question is a recall item of the regulations and the key is followed.
