What information is provided on a Ballast wiring diagram?

Ballast wiring diagrams contain information showing the grounding methods, input supply voltage and wire placement in an electric circuit. Wires are often colored in a ballast diagram with different colors to identify individual wires from common wires connected to lamp holders.

Ballast wiring diagrams vary in appearance depending on the amount of wires used, the number of individual connections and whether the circuit is a series or parallel circuit. Ballast wiring diagrams are designed to follow all government codes, and must include a ground connection for all ballasts to ensure proper installation and avoid potential safety hazards, such as shock hazards and damages.
