A bus is a repeatable way to share power. The handbook names five.

BUS BUILT FROM STRENGTH WEAKNESS

Fixed (F) Chain of electrical branches Each load gets a set amount in strict priority. Lower priority drops first Reserves power even when idle. 75 metal fragments per branch

Dynamic (D) Splitters, often in a pyramid Equal share, adapts when an output dies. 100 metal fragments All outputs fail together in a shortage. Chaining splitters shrinks the power fast

Configurable (C) Memory cell, branch and OR switch Only takes power when triggered, otherwise it passes along the main line More parts and logic to learn

Root combiner (RC) Root combiners Merges many sources into one line Depth limit of 16 along any path

Hybrid (H) A mix of the above Right bus per job Hardest to document and fix

Splitters power output 1 first, then 2, then 3, and odd leftovers go to output 1, then 2.

A C-bus can run four ways: set and reset automatically, toggle by hand, set automatically and reset by hand, or inverted so it flips only when the circuit dies.

Build RC buses as a pyramid, not a daisy chain. Eight sources reach depth 4 in a pyramid and depth 8 in a chain.
