Connector Types
Connecting caps are colored by size and useRedYellowGreen – primarily for ground

Wiring Rules
Neutral wire goes without interruption to every place in the circuit where current may be used
Neutral wire is connected to the silver-colored terminal.
The neutral wire is white.

Wiring Rules
Black or red wire is always connected to a brass- colored terminal.
Black or red wires carry “hot” power or current from the source to the devices within the circuit
![Page 15: Basic Electricity Facts and Diagrams. Cable Types Determine your need to determine the type of cable (Romex) needed Gage Size of the wire (common = 12.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649f395503460f94c556e8/html5/thumbnails/15.jpg)
Wiring Rules
The green, or bare, grounding wire is connected to the grounding terminal (green screw) of a grounding-type electrical fixture.
All wires must be spliced or connected to a terminal screw in each box.
Only one wire is allowed to be fastened under a terminal screw.
