Answer Posted / mohamed elias
The anti-pumping relay is a device in circuit-breaker whose
function is to prevent multiple breaker closures. For
instance, if the operator gives the closing command to the
breaker by pressing the close button and the breaker
closes. However, a fault in the system causes the breaker
to trip. Since the close command is still in the pressed
condition, there is a chance of the breaker closing again
and being tripped by the relay multiple times. This can
damage the closing mechanism of the breaker. The anti-
pumping relay prevents this by ensuring that the breaker
closes only once for one close command from the control
panel.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
