Terms of use

Last updated November 15, 2026

Information only

Our calculators and guides give general estimates for planning purposes. They are not electrical, engineering, medical or safety advice. Real performance depends on your equipment, environment and usage. Always follow manufacturer instructions, local electrical codes, and your doctor's guidance for medical devices. Have a licensed electrician install anything that connects to your home's wiring.

Accuracy

We work to keep specifications and prices accurate, but they change, and errors happen. Confirm details with the retailer before buying. Prices shown are those we saw on the date indicated and may not be current.

Third-party sites

Links may take you to retailers and other sites we don't control. Your purchases are between you and the retailer, under their terms, warranties and return policies.

Limitation of liability

To the extent permitted by law, WattWise Guide isn't liable for losses arising from your use of the site or reliance on its estimates. The site is provided "as is."

Intellectual property

Site content and tools are ours unless noted. Product names and trademarks belong to their owners and are used for identification only.
