Which wire can carry a higher current stranded wire or solid wire ?

The ability of a wire to carry current depends on several factors, including its cross-sectional area, material, and temperature rating. Both stranded and solid wires can carry high currents, but they have some differences.

1. Stranded Wire:

   • Advantages:
     • Flexibility: Stranded wire is more flexible than solid wire, making it easier to bend and route in tight spaces.
     • Fatigue Resistance: Stranded wire is less prone to metal fatigue caused by repeated bending.
   • Disadvantages:
     • Higher Resistance: Stranded wire typically has a slightly higher resistance than solid wire of the same gauge because of the air gaps between strands.
     • More Expensive: Stranded wire is often more expensive than solid wire.

2. Solid Wire:

   • Advantages:
     • Lower Resistance: Solid wire generally has lower resistance than stranded wire of the same gauge because there are no gaps between strands.
     • Lower Cost: Solid wire is often less expensive than stranded wire.
   • Disadvantages:
     • Less Flexible: Solid wire is less flexible and more prone to breakage when repeatedly bent.
     • Susceptible to Fatigue: Solid wire can be more susceptible to metal fatigue over time.

Conclusion:

• For higher currents, both stranded and solid wires are used, and the choice depends on the specific application and requirements.
• If flexibility and resistance to metal fatigue are important, stranded wire might be preferred.
• If lower cost and slightly better electrical conductivity are more critical, solid wire might be chosen.

Ultimately, the choice between stranded and solid wire for carrying higher currents depends on the specific needs of the application, the installation requirements, and other factors such as cost and ease of handling. It's essential to consider the context and requirements of the electrical system in question when making a decision.
