## Questions & Answers

**Q: why do you crimp the connector 3x?  One for each wire, what is the 3rd?**
A: I’m not sure why you have to crimp 3x’s unless their tool is designed that way? I only crimped  twice in my engine compartment of my pickup and have had no issues.

**Q: Will these work for 10/2 wire at 230V and 20 amps?**
A: You should be able to use on 230 volt 20 amp.  The yellow should handle 30 amp minimum. Usually if the wires fit in it. It will work

**Q: Do you have the Butt connectors that are 12-10 on one end and 16-14 on the other**
A: No, they are the same on each end. The colors indicate the size, as well they are labeled.

**Q: Can these be submerged? I want to use them for a bilge pump.**
A: Yes you can, the discription of the product says they are Marine Grade Waterproof Wire Connectors.
