# 1/0 vs 4/0 wire

• ### 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.

• ### Is there a difference between 1/1 AWG and 1/o?

• Not sure if this is the issue, but extra fine stranded cable is slightly larger than regular strand cable, and the connector (ring terminal?) should be sized accordingly. But looking at the title of this thread, are you referring the difference between #1 AWG and 1/O AWG? There is a difference, 1/O is one wire size larger.

• ### Does cable size 1/0 = 1?

• Some think cable size 1/0 = 1 (it does not) or possibly the other way round that 1 = 1/0 (that is wrong as well.) . Charles thank you for the explanation.
