How we build our price ranges

Every range published on ElectricalGuide is assembled from three layers: manufacturer list pricing for equipment (generators, panels, chargers, fixtures), published and collected contractor pricing for labor across U.S. markets, and the code requirements (NEC and common local amendments) that determine what a compliant installation actually includes: permits, inspection, required device types like AFCI/GFCI protection.

Ranges are national. Labor varies meaningfully between markets, and site conditions (access, wiring condition, panel capacity, distances) move real quotes within and sometimes outside our published bands. That is why every guide pairs its range with the factors that move it, and why we recommend comparing at least two itemized quotes for any project beyond a service call.

Pages carry a reviewed date and are re-checked on a rolling schedule, with priority on equipment-heavy categories where manufacturer pricing changes fastest.

ElectricalGuide is reader-supported: we connect homeowners who want to talk through a project with licensed local service providers by phone. That connection service is how the site is funded; the published ranges are researched independently of it.
