Terms of Use
Last updated 31 July 2026
Acceptance
By using InfraToolbox you accept these terms. If you do not accept them, please do not use the site.
The tools are for planning, not for certification
This is the important clause, so it is stated plainly. The calculators produce estimates for planning purposes. They are not engineering certifications, they do not constitute professional advice, and they must not be used as the sole basis for:
- Electrical installation or circuit sizing
- Structural or floor loading decisions
- Mechanical and cooling system design
- Life-safety systems of any kind
Always verify results against manufacturer documentation, the applicable standards, and a qualified engineer licensed in your jurisdiction. Local electrical and building codes take precedence over anything on this site.
No warranty
The site is provided "as is", without warranty of any kind, express or implied. While the calculations are unit-tested against known values and we correct errors promptly when they are reported, we do not warrant that the site is free of errors, available without interruption, or fit for any particular purpose.
Limitation of liability
To the fullest extent permitted by law, we are not liable for any loss or damage — including equipment damage, downtime, lost data, lost profits or consequential losses — arising from use of, or reliance on, this site.
Nothing in these terms excludes liability where it cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.
Acceptable use
You agree not to:
- Attempt to disrupt, overload or gain unauthorised access to the site or its infrastructure
- Scrape the site at a rate that degrades service for other users
- Use the site in breach of any applicable law
Intellectual property
The site's content, design and code are owned by their author. You may freely use the resultsthe calculators produce in your own work, including commercial work — that is what they are for. You may not republish the site's content or reproduce the tools as your own.
Third-party links and advertising
The site links to external resources and carries third-party advertising. We do not control that content and are not responsible for it. Advertising is handled as described in the privacy policy.
Changes
These terms may be updated. The date at the top of this page will change when they are, and continued use afterwards constitutes acceptance.
