CONNECTOR (SB350 2/0 BLUE)
Frequently Asked Questions
Q: What makes the blue SB350 2/0 connector different from the gray version?
A: The 317-1728-P blue SB350 2/0 connector has identical electrical specifications (350 amps, 2/0 AWG wire) as the gray version but is color-coded blue to identify a different circuit function or safety isolation purpose. Blue typically indicates a negative return, ground bus, or secondary battery circuit. Always follow your equipment wiring schematic to ensure correct color coding for your circuit.
Q: Can I use a blue SB350 2/0 connector interchangeably with a gray SB350 2/0 connector?
A: Electrically yes, but not recommended. The color coding serves a critical safety and diagnostic function. Mixing blue and gray connectors across different circuits can cause confusion during troubleshooting and may violate OEM wiring standards. Always replace with the same color code specified in your equipment documentation.
Q: Which equipment circuits use blue SB350 2/0 connectors?
A: Blue SB350 2/0 connectors are typically installed on Crown, Toyota, Raymond, Yale, and Hyster lift trucks for secondary power distribution, ground return paths, or isolated battery circuits. Some models use blue to mark auxiliary battery circuits separate from the main motor power. Consult your specific equipment wiring diagram to verify which circuit requires the blue connector.
Q: Does the blue color affect connector performance or durability?
A: No. The blue color is applied to the connector body only. The internal contact materials, amperage rating, and service life are identical to gray SB350 2/0 connectors. Blue connectors provide the same 7 to 10 year lifespan in standard conditions and are equally resistant to corrosion and oxidation.
Q: What wire gauge and voltage specifications apply to blue SB350 2/0?
A: The 317-1728-P blue SB350 2/0 connector is rated for 2/0 AWG wire, 350 amps continuous current, and operates on 24V to 72V DC systems. Peak current handling is 600 to 800 amps during motor startup. The connector must never be used on AC circuits or with voltages exceeding 72V DC.
Q: Is there a cross-reference equivalent to the blue SB350 2/0?
A: Other blue SB350 2/0 connectors from different manufacturers may be mechanically compatible, but always verify the voltage and amperage ratings match your equipment. The blue color designation may vary in meaning across different OEM brands. Do not assume all blue SB350 connectors serve the same circuit function on different equipment models.
