Rust’s electricity system powers lights, auto turrets, traps, farms and automation — but it confuses a lot of players. This guide builds your foundation: where power comes from, how wiring and power draw work, the most useful components, and the common circuits you’ll actually build.
Where power comes from
- Small Generator — burns low grade fuel for steady, reliable power; great for turrets but costs fuel.
- Wind Turbine — free power that varies with wind speed and height; mount it as high as possible.
- Solar Panel — free power during the day, nothing at night; angle it at the sun.
- Test Generator — an infinite-power tool for building and testing circuits (not for live bases).
- Batteries — store surplus power so your base keeps running when wind drops or the sun sets. Essential with solar/wind.
How wiring works
Power flows from an output, through wire, into an input — and most components pass power through, so you can chain them. The key concept is power draw: every component (a turret, light or trap) consumes a set amount of power, measured in rWm. If your source can’t cover the total draw of everything downstream, things at the end shut off. A common beginner trap: batteries reduce the available output while charging, which can starve your circuit — plan your power budget before wiring.
Useful components
- Splitter — divides power evenly across three outputs.
- Switch / Timer / Counter — control when circuits turn on and off.
- Root Combiner — merge two power sources (e.g. solar + battery) into one line.
- Blocker, AND/OR/XOR switches, Memory Cell — logic gates for smarter automation and base security.
- Electrical Branch — pull a fixed amount of power off a line for a sub-circuit.
Common circuits
Most bases start with a simple auto-turret circuit (power source → battery → turrets) for defence, then add shotgun-trap and flame-turret circuits at choke points, and lights and an indoor farm (ceiling lights + sprinklers) for crops. Plan your power budget first so a full turret line doesn’t brown out your atmospherics, lights or farm. See our farming guide for powered grow setups.
