Frequently Asked Questions

Q: Is 813972926 compatible with standard 6.3mm Faston receptacles?
A: Yes. The 6.3mm terminal tab is the Faston standard – compatible with any 6.3mm Faston receptacle or housing in the same series.

Q: What wire gauge should I use for a 20A circuit?
A: Use a minimum of 14 AWG (2.0 mm²) for 20A continuous load. For 15A circuits, 16 AWG (1.0 mm²) is acceptable. Undersized wire causes voltage drop and connector overheating.

Q: What crimping tool is needed?
A: Use a ratchet crimper rated for 14–16 AWG – such as the Engineer PA-20 or equivalent heavy-duty ratchet crimper. Standard small-gauge crimpers are too small for 6.3mm terminals.

Q: Can this be used for 24V truck applications?
A: Yes. The 6.3mm series is rated for 12V and 24V DC systems.
