Recommended Maximum Amperage is based on an Ambient
Temperature of 40°C (104°F) and not more than three current carrying
conductors in a raceway/conduit or bundled and directly buried. For
de-rating factors for higher ambient temperatures consult Tempco’s
engineering data on Catalog Page 6-10.
For more information consult the National Electrical Code, Articles
310-15 through 310-84.
NOTE: For nickel wire conductor and other high temperature lead wire consult Big Chief.
