Informational use

The calculators and articles are provided for general informational and reference purposes. They do not replace site-specific electrical design, inspection, manufacturer instructions, or advice from a qualified professional.

Your responsibility

You are responsible for confirming input values, voltage relationships, phase configuration, equipment ratings, applicable standards, and the suitability of any result before relying on it.

Availability and accuracy

We work to keep the site accurate and available, but we do not warrant uninterrupted access or that every result will fit every installation. Formulas may produce mathematically correct values while additional engineering constraints still apply.

Acceptable use

Do not misuse the site, attempt to disrupt it, automate abusive traffic, interfere with other visitors, or present our content as professional certification of an installation.

Changes

We may update these terms as the site evolves. Continued use after a published update means you accept the revised terms.
