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 (with output numbers), how wiring and power draw work, the components you’ll use, and the common circuits you’ll actually build.
Power sources & output
| Source | Output | Notes |
|---|---|---|
| Solar Panel | Up to 20 | Daytime only; angle at the sun |
| Wind Turbine | 0–150 | Varies with height & wind; mount high |
| Small Generator | 40 (steady) | Burns low grade fuel — reliable but costly |
| Small Battery | 10 out | Lights, sensors |
| Medium Battery | 50 out | Turrets + lighting for a small base |
| Large Battery | 100 out | Complex circuits, large systems |
| Test Generator | Infinite | Building/testing only — not for live bases |
The golden rule: never wire devices directly to solar or wind — solar dies at night and wind is random. Always feed generation into a battery first, then run your devices off the battery for steady power.
How wiring & power draw work
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 device consumes a set amount. If your source can’t cover the total draw of everything downstream, devices at the end shut off. Two gotchas: batteries reduce available output while charging, which can starve a circuit, and you only get 16 connections from a source to a device — exceed that and the circuit dies. Plan a power budget before wiring.
| Device | Power draw |
|---|---|
| Auto Turret | 25 (nonstop) |
| Electric Furnace | 60 |
| Lights / sensors | 1–2 each |
Useful components
- Splitter — divides power evenly across three outputs.
- Electrical Branch — pull a fixed amount off a line for a sub-circuit.
- Switch / Timer / Counter — control when circuits turn on and off.
- Root Combiner — merge two sources (e.g. solar + battery) into one line.
- Blocker, AND/OR/XOR switches, Memory Cell — logic gates for automation, alarms and traps.
Common circuits
Most bases start with a simple auto-turret circuit (source → battery → turrets) for defence, then add shotgun-trap and flame-turret circuits at choke points, plus lights and an indoor farm (ceiling lights + sprinklers). Budget power first so a full turret line doesn’t brown out your lights or farm. See our farming guide for powered grow setups.
Frequently asked questions
How much power does an auto turret use in Rust?
25 power, continuously. Four turrets need 100 power on tap, which is a large battery or a strong generation source behind a battery. Always size your power supply to the total turret draw or the last ones in the chain won’t fire.
Solar, wind or generator — what’s best?
Solar (up to 20) is the cheap early option but daytime-only; wind turbines (0–150) give the most but are inconsistent; the small generator gives a steady 40 at the cost of low grade fuel. Most bases combine a free source charging a battery, with a generator as backup.
Why does my Rust circuit keep turning off?
Usually power draw exceeds supply, a charging battery is eating your output, or you’ve passed the 16-connection limit between source and device. Feed devices from a battery, check the total draw against your output, and keep wire chains short.
