In electrical work, a home run refers to a wire that runs directly from a device or outlet back to the electrical panel without being spliced or connected to other devices along the way. It is a term homeowners often hear during renovations or new construction discussions, so understanding it helps make sense of what your electrician is planning. Here is what it means in practice, from the licensed electricians at EZSMART, serving Toronto and the GTA.
In a typical residential circuit, multiple outlets, switches, or fixtures share a single wire that daisy-chains through them and eventually returns to the panel. A home run, by contrast, provides one specific device with its own dedicated wire directly from the panel, meaning that device does not share power with anything else on the run.
Understanding home run wiring helps clarify why some electrical additions, like an EV charger or a new range, involve running a new dedicated wire back to your panel rather than tapping into an existing circuit. It also explains why these installations sometimes require panel work if slots are limited, and why they carry different cost implications than adding an outlet to an existing shared circuit. Work involving new home run circuits should be permitted through the Electrical Safety Authority.
Do all outlets in my home have home run wiring?
No, most standard outlets share a circuit with other outlets. Home runs are typically reserved for higher-draw or code-required dedicated circuits.
Is home run wiring more expensive to install?
Generally yes per device, since each home run requires its own dedicated wire and panel slot rather than sharing with existing wiring, but it is often necessary for specific applications.
Can existing shared circuits be converted to home runs?
Yes, this is a common upgrade during renovations or when adding new appliances, though it involves running new wiring back to the panel.
