Results Are Estimates

Results depend entirely on the values and assumptions entered. Simplified equations may omit harmonics, reactance, temperature, conductor material, duty cycle, tolerances, aging, transient conditions, nonlinear loads, or other real-world factors.

Not a Code-Compliance Tool

Unless a page explicitly identifies a code edition and table, NodeAndVolt does not determine compliance with the National Electrical Code, local amendments, IEC standards, utility rules, or another jurisdiction's requirements.

Not a Substitute for Professional Review

A qualified professional must evaluate actual site conditions, equipment ratings, protection, grounding, fault current, installation methods, and regulatory requirements. Always follow manufacturer documentation and the authority having jurisdiction.

Use Safe Work Practices

Do not work on energized electrical equipment unless you are trained, authorized, properly equipped, and following an approved safe-work procedure. De-energize and verify whenever required.
