Preliminary Planning Disclaimer
All calculations, formulas, wiring diagrams, and equipment sizing models on CalcMyPower.com are provided strictly for preliminary planning, screening, and educational purposes.
They do not constitute licensed Professional Engineer (PE) designs or certified electrical contractor advice. Electrical installations carry life-safety, fire, and shock hazards. Always consult a licensed electrician and verify local building codes prior to physical installation.

If you do not agree with any of these terms, you are prohibited from using or accessing this site or its interactive calculation tools.
2. Mathematical Models and Technical Accuracy
CalcMyPower develops calculators grounded in authoritative published baselines, including National Electrical Code (NEC / NFPA 70), IEEE standards, and NREL photovoltaic performance models.
However, actual electrical operating parameters vary based on ambient temperature, altitude, wire length, motor power factor, manufacturing tolerances, and equipment age.
We make no representations or warranties regarding the mathematical certainty or fitness for a particular physical installation of any output generated by our tools.
3. Limitation of Liability
In no event shall CalcMyPower, its contributors, or its authors be liable for any damages (including, without limitation, damages for equipment damage, electrical fires, power outages, data loss, or personal injury) arising from the use or inability to use our calculation tools.
