Common Technical Questions:

Can this jumper bar be used in non-York applications?
This component is engineered as a York OEM HVAC part. While the 100A and 4P ratings are standard, the physical dimensions and mounting hole spacing are proprietary to specific York/Source 1 equipment footprints.

What is included in the accessory kit?
The S1-3500-378P includes the jumper bar itself along with the specialized mounting hardware or insulators required to maintain proper electrical clearance within the distribution block.

Is this suitable for 3-phase power distribution?
Yes, the 4-pole design allows for flexibility in bridging 3-phase circuits while providing an additional pole for neutral or auxiliary jumpering depending on the specific wiring diagram of the unit.
