How about 4,000 watts of halogen lamps of 8 PCs, how many amps of magnetic contactor to be used

1.5 What is it?

[@gillansimpungwe5482]

But why having the contactor with high rating than the main breaker

[@chrissantos7865]

The cb is what protects the circuit the contactor must withstand the current

[@kassahunnegash2944]

DOL is implemented in low power i.e single phase system;5HP is single phase but u calculated as 3phase HOW?

[@mahmoodmulthajim9290]

The direct online (DOL) starter method of an induction motor is simple and economical. In this method, the starter is connected directly to supply voltage. By this method, small motors up to 5 kW rating are started to avoid the supply voltage fluctuation.

[@mahmoodmulthajim9290]

in here connected load is 3.73 kw

[@jagalreddy9695]

Useful knowledge sir

[@jakejp9569]

Why 1.5 for 50% safety factor
