About the project
ElectraKit is a free collection of electrical calculators and references for residential, commercial, and industrial field work in the United States. The tools support common estimates and checks while showing the assumptions behind each result.
Who maintains ElectraKit
ElectraKit is built and maintained by one independent developer. It is a standalone website, not an electrical contractor, engineering firm, inspection service, or code authority.
Using the tools
Each result is limited to the inputs, method, and assumptions stated on its page. Verify the adopted electrical code, local amendments, equipment instructions, installation conditions, and project requirements before making or approving electrical work.
Feedback and corrections
To report an issue or suggest an improvement, email [email protected]. Include the page and relevant inputs, but do not send confidential project information.
