FAQ
6. Common Questions and Quick Answers
Q: Can I use 18 AWG instead of 16 AWG if the device only needs a little power?
A: Technically, yes, if the device's current draw is well within the safe limit for 18 AWG and the wiring distance is short. However, it's always a good idea to check the device's documentation for specific recommendations. When in doubt, it's always safer to use the thicker wire.
Q: What happens if I use a wire that's too thin for the application?
A: Using a wire that's too thin can lead to overheating, which can melt the insulation and potentially cause a fire. It can also cause voltage drop, which can affect the performance of your device. In short, it's not a good idea!
Q: Is stranded wire or solid wire better?
A: Stranded wire is more flexible and is generally preferred for applications where the wire will be bent or moved frequently. Solid wire is less expensive and is often used for in-wall wiring where flexibility isn't as important.
Q: Where can I find the maximum current rating for different wire gauges?
A: You can find charts online that specify the safe current carrying capacity for different wire gauges. Keep in mind that these ratings can vary depending on factors like the wire's insulation type and the ambient temperature.
Q: Does wire length matter when choosing between 16 AWG and 18 AWG?
A: Absolutely! The longer the wire, the more voltage drop you'll experience. For longer runs, you'll generally want to use a thicker wire (like 16 AWG) to minimize voltage drop and ensure that your device receives enough power.
