Preparing the interactive tool. Please wait; the guide and worked examples remain available below.
1. Identify the port before moving wires
The Electrical Branch has one Power In and two distinct power outputs. Branch Out is the configured side; Power Out carries the remainder. A Switch has Power In, Power Out, plus separate Switch On and Switch Off control inputs. A wire that reaches the wrong port can look almost right while delivering no useful output.
| Part / port | Role | Diagnostic question |
|---|---|---|
| Electrical Branch — Power In | Incoming power | Does the source’s output reach this input? |
| Electrical Branch — Branch Out | Configured branch leg | Is its output setting sufficient for the consumers on this leg? |
| Electrical Branch — Power Out | Remainder leg | Did the next component get connected to this port instead of Branch Out? |
| Switch — Power In / Power Out | Switched power path | Is the switch in the on state and does the output feed the intended consumer? |
| Switch — Switch On / Switch Off | Control inputs | Is a control signal toggling state, rather than being mistaken for the power path? |
2. Trace the circuit in a safe order
- Start at the generator, turbine, solar panel, battery, or other source. Read its current output in-game; a listed maximum is not proof it is producing that amount now.
- Follow the wire into the first component’s Power In. Confirm the line is connected and does not end at an adjacent but incorrect input.
- At each Branch, note the displayed/set Branch Out amount and identify which leg the target consumer is actually on. Continue from the correct output port.
- For a Switch, flip it manually once and observe whether its own Power Out changes. If you wired a control line, verify it reaches Switch On or Switch Off, not Power In.
- At the consumer, verify its Power In and any state/on condition. Then return upstream to find the first point where expected power stops.
3. Distinguish three common branch mistakes
| Symptom | Likely wiring/configuration issue | Next check |
|---|---|---|
| Everything after a Branch is dead | No input power, wrong input port, or upstream source is not producing | Inspect source output and Branch Power In before changing the set amount. |
| Branch Out devices work, downstream chain does not | The chain may be on Branch Out rather than the remainder Power Out | Trace the two output paths and move only the intended connection. |
| Switch receives signal but appliance stays off | Signal/control wiring and switched power path are being conflated | Trace Switch Power In → Power Out, then check its on state. |
| It worked before changing Branch Out | The requested branch budget or remaining supply may no longer cover loads | Compare the source, branch setting, and visible consumer demand in the local tool; verify actual values in-game. |
| A published blueprint uses older behavior | The schematic may predate electricity changes | Compare its claims with current Facepunch item pages and update notes. |
4. Budget the branch with actual readouts
Enter the source output you can currently observe, the Branch Out setting, and the demand of consumers on that branch in the private planner. It flags only arithmetic mismatches in those values. It cannot model every component’s active-usage rule, battery behavior, state, or server changes; Rust’s own live readouts and a one-wire-at-a-time test remain decisive.
- List only consumers fed by that Branch Out leg; do not add loads on Power Out to that subtotal.
- Use current observed values, not a solar panel or wind turbine’s best-case maximum.
- If your sum exceeds the set Branch Out amount, raise the configured amount only after confirming the upstream remainder still supports other circuits.
- Toggle the switch and re-read the consumer state after each change. Keep a note of the known-working wiring before rebuilding a larger circuit.
5. Compare community schematics carefully
Steam threads and community guides can help you spot a familiar wiring pattern, but they may use different item states, patched behavior, or a modded server. Facepunch’s Waves of Change notes explicitly changed electrical-branch behavior and fixed usage calculations; prefer those notes and current port descriptions when a community post conflicts. Reproduce a circuit in your own base only after you understand what each leg is meant to do.
Before you play
- I checked the live Rust UI and current server/platform scope.
- I recorded the relevant settings rather than relying on a generic community build.
- I changed one variable at a time and verified the result in game.
Frequently asked questions
Does this guide inspect my server?
No. It uses published Facepunch sources and values that you verify in your own UI.
Can server settings change the outcome?
Yes. Console parity, community-server multipliers, plugins and custom settings may differ; the live server rules and UI are authoritative.
