About

Calcwise is a free calculator site available in six languages. The electrical calculators were prepared by a team with hands-on experience in electrical panel manufacturing, water pumping, solar energy and industrial automation.

How we work

• Every calculator shows its formula and the standard or table it relies on (IEC 60364-5-52, NEC 310.16…).
• Calculations run in your browser: we do not store or send the values you enter.
• We review the calculators when standards change or when an error is reported.

Limitations

Results are for guidance only. For installations, permits, or financial and health decisions, consult a qualified professional.
