Terms of Use & Engineering Disclaimer

Please review these terms carefully before utilizing the calculation engines and engineering data on CurrentSpec.com.

1. Educational & Preliminary Design Scope Only

All calculators, charts, formulas, guidelines, and tables published on CurrentSpec.com are provided strictly for educational, informational, and preliminary system design reference.

Nothing contained on this website constitutes licensed professional electrical engineering advice, professional system certification, formal architectural review, or an official determination of code compliance.

2. Decoupling of Calculated Basis from Equipment Selection

Calculated sizing values (such as conductor circular mil area, derated ampacity, fuse rating basis, or conduit fill percentage) represent theoretical mathematical models based on nominal standards (such as NEC Chapter 9 Table 8 or ABYC E-11 Table 6B).

The final selection, procurement, and installation of physical components (conductors, overcurrent protection devices, disconnect switches, busbars, and inverters) must account for physical equipment manufacturer terminal torque ratings, thermal ratings, short-circuit current interrupt capacities (AIC), crimp resistance, and localized heat dissipation.

3. Limitation of Liability

Electrical systems—particularly high-current DC battery banks, AC shore power circuits, and high-voltage photovoltaic strings—carry inherent hazards including fire, arc flash, toxic gas emission, battery thermal runaway, severe electrical shock, and electrocution.

To the maximum extent permitted by applicable law, the authors, contributors, and operators of CurrentSpec.com disclaim all liability for any direct, indirect, incidental, consequential, special, or exemplary damages, injuries, equipment damage, or property losses arising from or in connection with the use, misuse, or reliance upon any calculation, tool, or information provided on this website.

4. Independent Verification & Code Compliance

Users are solely responsible for ensuring that any physical installation complies with all applicable local, regional, and national electrical codes, including NFPA 70 (National Electrical Code), ABYC Standards, CFR titles, and requirements established by the local Authority Having Jurisdiction (AHJ). All installations should be verified and inspected by licensed electrical contractors.
