Wiring SchematicsDetails for the ElectricianWiring SchematicsAnswer offers three different wiring schematicsto allow you to match your specific wiring strategyto any typical building wiring plan.Tip: All the components in an electrical systemmust use the same wiring schematic. Thecomponents are keyed and color coded to makeit impossible to connect mismatched parts.Black = Four-circuit, 3+1Brown = Four-circuit, 2+2Rust = Three-circuit, separate neutrals (3SN)Shared neutrals = 10 gaugeNon-shared neutrals = 12 gaugeHot wires = 12 gaugeFour-Circuit, 3+1Circuit Panel 1PHASE PHASE PHASEA B CCircuit 1 HotCircuit 2 HotCircuit 3 HotCircuits 1, 2, and 3 NeutralNEUTRALGroundGROUNDCircuit Panel 2PHASE PHASE PHASEA B CCircuit 4 HotCircuit 4 NeutralNEUTRALGroundGROUNDIn the four-circuit 3+1 schematic, circuits1, 2, and 3 are distributed from the first circuitpanel and are supported with one shared neutraland one shared ground.
