Generator install and connection guides
Three pages cover the hardware that connects a portable generator to a house panel: an interlock kit finder, a manual transfer switch finder, and a comparison of the two that also explains the power inlet box both of them need.
The interlock finder works from what is printed on your panel — the manufacturer and the panel family — because an interlock kit is listed for specific panels, and one made for a different panel either does not fit or is not approved for yours. The transfer switch finder compares the documented 30 A and 50 A options by circuit count.
None of these pages explain how to wire anything. Installing an interlock, an inlet box or a transfer switch is work inside the service panel, and each page marks the point where a licensed electrician takes over. The product data comes from the panel and switch makers' own catalogs and instruction sheets, cited on each page.
All pages, A–Z
| Page | In one line | DIY? |
|---|---|---|
| Generator Interlock Kit Finder: Match the Panel, Not the Picture | Look up manufacturer-published generator interlock kits for Square D, Eaton and ABB/GE load centers by family, series or catalog number. | Licensed pro / dealer |
| Generator Interlock Kit vs Manual Transfer Switch (and the Power Inlet Box Both Need) | An interlock kit is a $50–130 bracket on your existing panel that lets you run any circuit, one main-or-generator at a time; a manual transfer switch is a $300–500 box that moves 6–16 chosen circuits and shows load on meters. | Licensed pro / dealer |
| Manual Transfer Switch for a Generator: Find the Right Type | Choose a manual transfer switch by generator outlet, circuit coverage and whether you need a complete inlet-and-cord kit. | Licensed pro / dealer |
