Can a NEMA size 4 starter be converted to a contactor only?
No. The base plate cannot be removed so that the space requirment is the same as if the overload relay were present. The position where the contactor load lugs will be connected will have an exposed bus of approximately 1``. This is a safety issue. We recommend using the overload jumper strap kit, 9998SO31. There are two straps in this kit so 2 kits will be needed. This will provide a safe and clean looking bypass for the overload relay and not take up any additional panel space.
