hook up wire?

Question

can anyone please tell me what does hook-up wire mean and how does it differ from other kinds of wires such as light duty and heavy duty?Also,which one should I use for breadboards?

Answer 1

Hookup wire is a term usually reserved for wire sizes smaller than 16 AWG, usually single strand conductor. It is generally used in applications where current-carrying capacity is not of prime importance. Breadboarding is one of these applications, but usually uses 22AWG or smaller wire.
