## Questions & Answers

**Q: i need to connect 2 wires in one end and 1 wire in the other end, the 2 wires fit perfectly, is it ok to do it this way?**
A: Yes, you can crimp more than one wire into a crimped splice at each end as long as you are using a connector size large enough to fit the wires but not too large to not crimp tight on the single wire end.  Additionally, solid strand wires should never be twisted before crimping; braided strand wires should only be lightly twisted (in the same direction as their inherent twist) to allow for an easier insertion before crimping.

**Q: Can these fittings be used with solid copper wire as well as the stranded?**
A: No

**Q: Can this be used with low voltage wire for a robot lawn mower boundary wire?**
A: I’m not sure how to answer that exactly. I’ve used it from 12 volt to 48 volt applications with my kids toys and but connectors have worked great and the krimper is awesome. Have used other kinds and have had issues with  krimpers splitting heat shrink.  And to have this all in a very durable case is icing on the cake.

**Q: Are these for automotive wiring only or can it work for home wiring projects (lamps, fans, etc.)?  What are the voltage limits?**
A: I use these for 6, 12, and 24 volt DC.  I could see where someone might use these for some low voltage AC applications but not many.  You will also want to check codes in your area (for instance, I might see a fork or ring connector on the screws on a 120V 15 amp receptacle in some areas) but all in all, I believe they're only rated for 12 volts DC.  This is my opinion- you should consult a licensed electrician in your area for your specific needs.

### ⭐⭐⭐⭐ Review
*by M***N on 28 October 2025*

The connectors themselves are great, they crimp well and the heat shrink works nicely. I docked this kit 1 star because the hinges on the organizer box broke, meaning I have to be careful how I transport and open these.
