Generator Wiring Diagram
When a storm knocks the power out, a portable generator can keep the fridge, the furnace, and a few lights running until the utility comes back. ArcSite's generator wiring diagram traces the path from the generator's cordset through a power inlet box to the home panel, next to the existing utility feed.
Key Features
This generator wiring diagram includes:
- Utility power lines and electric meter
- Existing feed to the main breaker
- Home panel
- Utility power return alert above the panel
- Portable generator
- Cordset running to a power inlet box
- Generator metering between the inlet box and the panel
The utility power return alert tells the homeowner when grid power is back, so they know when to shut the generator down and switch over.

Why a Generator Wiring Diagram Matters
Frequently asked questions
Does this diagram show an interlock or a transfer switch?
Not separately. It shows the hookup path from the generator to the panel. Add the interlock kit or transfer switch you're installing in ArcSite, since one of them is required to keep the generator from backfeeding the grid.
Can I swap in a standby generator?
Absolutely. Replace the portable unit with a standby generator in ArcSite and update the connection to match.
Can I price the generator hookup on the spot?
You can. Once the inlet box and panel are on your drawing, send the proposal from the homeowner's garage instead of typing it up that night.
