So Cable Ampacity Chart

This amp chart highlights the types of cords gauge size range number of cord coductors ampacity of current carrying conductors and much more.

So cable ampacity chart. This table should only be used as a starting point when establihsing ratings for any given situations. Our new ampacity calculator app can help determine the ampacity of conductors in conduit cable or directly buried wires. It is rated to 600 volts and has a temperature range of 40 c to 90 c. Or cable exceeds three or where single conductors or multi conductor cables are stacked or bundled longer than 24 inches without maintaining spacing and are not installed in raceways the allowable ampacity of each conductor shall be reduced as shown in the following table.

The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Soow cord from allied wire cable is manufactured with the highest quality materials. Replace rather than patch a damaged cord or cable. Common applications include wiring for industrial machinery enormous appliances heavy duty tools motors and temporary electrical power and lighting for construction sites.

Where the number of current carrying conductors in a raceway or cable exceeds 3 the allowable ampacities shall be reduced per the table below. The use of this table for establishing ampacity ratings is an inexact procedure. Use the stayonline wire ampacity chart to look up the rated amperage of different sizes and types of cords. So cord is a multi conductor power cable that can be operated both inside and outside environments.

The cable is rated 40 c to 90 c water oil and weather resistant.

Usually a general purpose house circuit is designed for 20 amps. Tables 400 5 a and 400 5 b list the allowable ampacity for flexible cords and flexible cables with not more than three current carrying conductors at an ambient temperature of 86 f.

Southwire type soow flexible cords are designed for extra hard usage on industrial equipment heavy tools battery chargers portable lights welding leads marine dockside power power extensions and mining applications. Never use a flexible cord or cable in place of a permanent wiring method.
