Frequently Asked Questions
Q: What is the connector type and amperage rating for SKU 317-1721-P?
A: The 317-1721-P is an SB50 series #10 gray connector rated for 50 amps. This size is commonly used in battery disconnect and power distribution circuits on electric lift trucks and material handling equipment. The gray color indicates this is a standard power connector.
Q: Which electric lift truck brands use SB50 #10 connectors?
A: SB50 #10 connectors are used across multiple OEM brands including Crown, Toyota, Raymond, Yale, and Hyster electric pallet jacks and lift trucks. Verify your equipment model year and voltage system (24V, 36V, 48V) to confirm fitment before ordering.
Q: What wire gauge does the SB50 #10 connector accommodate?
A: The SB50 #10 connector is designed for #10 AWG wire, which is suitable for 50-amp circuits. Do not force larger or smaller gauge wire into this connector as it will not seat properly and can cause arcing or connection failure.
Q: What is the typical lifespan of this connector in field use?
A: Gray SB50 connectors typically last 5 to 8 years in normal material handling environments. Connectors used in wet storage, outdoor conditions, or heavy cycle operations may degrade faster due to corrosion or oxidation on the contact surfaces. Replace immediately if you observe pitting, loose contacts, or increased resistance at the connection.
Q: Is there an equivalent cross-reference part or alternative connector?
A: The SB50 #10 connector is a standard Anderson Powerpole compatible connector. Other gray SB50 connectors from different manufacturers may be mechanically compatible, but always verify voltage and amperage ratings match your equipment specifications. Do not mix connector types from different manufacturers on the same circuit.
Q: What causes premature failure of SB50 connectors?
A: Common failure causes include loose wire terminations, corrosion from moisture exposure, repeated connect/disconnect cycles without proper contact maintenance, and undersized wire that cannot properly fill the connector cavity. Inspect connectors regularly for visible corrosion or discoloration. Clean contact surfaces with a dry cloth if light oxidation is present.
