The RUST Splitter is a deployable electricity component used for splitting power into three parts. Facepunch added electricity components in the Electric Anniversary update on the 7th of December, 2018.
Players may deploy splitters on most surfaces and use a Wiring Tool to connect to its Power In and 3 Power Out ports. They require 1 power (each) to run and then divert any remaining power equally among its USED power output ports.
A popular misconception is that power will be split evenly among all 3 outputs regardless of attached devices, but if only one device is attached, it will act as a single passthrough. If two devices are attached, it will split the power in 50/50, and with all three, it splits 33/33/33.
Splitters may be found in an assortment of low-to-mid-tier crates, as well as drops from a wide range of scientists. Players may also research them or invest scrap into the Tier 1 Workbench tech tree.
