Wire & Cable

Recommended Wire Gauge Calculator

Bulk Wire has created an online recommended wire gauge calculator that helps determine the correct wire gauge for your application based upon the input parameters of length, current, voltage and more. The recommend gauge is the result of applying ABYC Standards factors, allowable voltage drop and any additional derating factors.

Wire gauge reference table

Bulk Wire has created an online table that provides measurements and conversion suggestions for wire gauges used throughout this website.

Use our wire gauge reference table if you have an existing wire or cable product with an unknown gauge, and need to determine the nearest gauge from the measurement of the bare conductor diameter.

Use our wire & cable spool size table to find the spool/bobbin dimensions for wire & cable products sold through this website.
