4-Circuit, 3+D

Features:

3 circuits share 10 Ga. neutral, allowing for three-phase current cancellation for high-power efficiency.
a shared 10Ga. neutral to manage harmonics
one isolated-ground circuit for specific equipment.
80 amps, 4 circuit/8 wire situations
60 amps, 3 circuit/5 wire situations

Application: Appropriate when building standard is 208y/120 volt power distribution (common neutral for three circuits) and an additional circuit is desirable or needed for specific equipment such as a personal computer, or an isolated-ground circuit is required.

3-Circuit, Shared Neutral

Features:

3 circuits share 10 Ga. neutral, allowing for three-phase current cancellation and high-power efficiency
a shared 10Ga. neutral to manage harmonics
one building-ground circuit
60 amps, 3 circuit/5 wire situations

Application: Appropriate when the most effective interface with a 208y/120 volt power distribution system is desired.

3-Circuit, Separate Neutral

Features:

3 circuits, each circuit having its own neutral
up to 3 isolated-ground circuits
one building-ground circuit
60 amps, 3 circuit/8 wire situations

Application: Appropriate when either a 240y/120 volt or 208y/120volt power distribution system exists and separate neutral circuits are required.

4-Circuit, 3I+1

Features:

3 circuits share 10Ga. Neutral, allowing for three-phase cancellation of electronic current for high-power efficiency
a shared 10 Ga. neutral to manage harmonics
one circuit for general purpose use
3 isolated building-ground circuits
80 amps, 4 circuit/8 wire situations
60 amps, 3 circuit/5 wire situations

Application: Appropriate in areas where a high concentration of technology products (computers, printers) are needed, minimal amounts of conventional equipment exists and isolated grounding is of primary concern.

4-Circuit, 2+2

Features:

2 circuits share 10 Ga. neutral and some current cancellation for moderate power efficiency
a shared 10 Ga. neutral to manage harmonics
2 building-ground circuits for general purpose use
2 isolated-ground circuits
80 amps, 4 circuit/8 wire situations

Application: Appropriate in areas where moderate amounts of technology products are used, and where separation from other circuits and isolated grounding are required.
