What we can’t do
We can’t provide personal electrical advice, design or approve an installation, or test products on request. Our work is based on published research, specifications and calculations. We have not hands-on tested the products on this site.
For device compatibility or installation questions, check with the equipment maker or a qualified electrician. Read how we calculate for the limits of our estimates.
