When we compare Solid wire and Standard wire, solid wires are constructed of one single piece of metal where Stranded wires are made of multiple small strands group together to make up a single wire or conductor.
Solid wire is tougher than a stranded conductor but rigid and less flexible than a stranded conductor. Hence, solid wires are more likely to break if it is frequent flexing.
Both wires are suitable for domestic and commercial.
usage but which wire can carry a higher current standard wire or solid wire?
Yes! Stranded wire because the current will not be inside the wire, but it will cover each thin wire in the stranded wire.
It is the multiple stranded wire that carries high AC currents due to the “skin effect“.
A solid wire can take a higher current in case of low frequency, but in high frequency like RF, solid wire carries less current due to skin effect.
Now for DC currents, it is still the multiple stranded wire since now the cross ection area of the core is utilized for this case. In the case of heating in a stranded wire due to the flow of high currents, there will be an expansion in the strands and hence cooling up the wire.

Some more information about standard and solid wire

1. Stranded Wire

Because they are bundled, stranded wires are relatively more flexible, intricate, and delicate. They are better suited for indoor use on circuit boards, speaker wires, electronic devices, etc., where bending and twisting are necessary to connect electronic components. For example, an ideal application of stranded wire is in a car door where frequent bending will occur.

Stranded Wire Pros

The bundled braids of stranded cable offer a few acute benefits over the solid wire:

  • Flexible
  • Malleable
  • Will not split or sever

Stranded Wire Applications

Stranded wires are more suited to indoor applications where bending and twisting are necessary to connect electronic components like:

  • Circuit boards
  • Speaker wires
  • Electro-mechanical assemblies

2. Solid Wire

Solid wire is heavier, made for all-weather conditions, is anti-corrosive, rugged, and can withstand frequent, but minimal movement. An ideal application of solid wire would be carrying power through a building structure, as this requires a high current, little movement, and long-lasting durability.

Solid Wire Pros

  • Weather-resistant
  • Anti-corrosive
  • Low cost

Solid Wire Applications

Solid wires are more suited for outdoor or heavy-duty applications where higher currents and more rigid durability are required.

  • Building infrastructures
  • Vehicle controls
  • Outdoor applications
