  • What is the size of the wire?

  • The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles.

  • How to calculate wire gauge size chart?

  • What size wire do I need for a branch circuit?

  • Branch circuit wire sizes for long runs: The long-run wire sizes given in the table above are for typical residential branch circuits up to 50A. These circuits are 120VAC (single phase) single conductor. Three phase power typically reduces the wire size to the next smaller. Cable size recommended based on voltage drop calculations.

  • What size wire do I need for a building inspector?

  • Fortunately for building inspectors, even though wire thickness varies among manufacturers, you can generally find the measurement closest to one of the standard sizes and you’re likely to be correct. Branch circuit electrical wire sizes such as the #14 copper electrical wire shown just below are also included in the tables in this article.
