Where do the violet and red wires go when fitting the overload to a DOL starter?
Violet 95 to 14
Red L1(1) to 96
Where does the black wire connect when fitting the overload to a single phase DOL starter?
T1 on the overload to L2(3)
Why is the star delta overload range different to DOL?
On a star delta starter the overload and contacts are phase connected so the overload and current ratings are 0.577 of line current ie1/1.732
What if the overload trips during starting?
Run up times more than 15 seconds may cause the overload to trip. A star delta starter could be wired to remove the overload from circuit during starting when star connected.
Incorrect or open circuit motor connections could also trip the overload – on a star delta typically when changing to delta.
