Feeder circuit diagram. A typical radial feeder system is shown schematically in Figure 2. Where flexibility is needed at the generator connection, use Type W or a listed flexible assembly with THWN-2 conductors. RMC provides strong mechanical protection and is required in many jurisdictions for the generator room feeder run. In contrast, a medium voltage switchgear compartment typically constitutes a single functional unit. 3/0 - (200 Amps)- Service entrance and feeder cable 1/0 (150 Amps) - Service entrance and feeder cable 2 Gauge (95 Amps) - Large water heater elements 4 Gauge (70 Amps) - Electric furnaces, large electric heaters 6 Gauge (55 Amps) - Furnaces, cooktops and electric ranges 10 Mar 3, 2026 ยท Current flows from the incoming compartment, through the incoming circuit breaker to the main busbars, and is then distributed from the main busbars to each outgoing feeder compartment and onwards to the loads via their respective outgoing switches. Size branch circuits in accordance with the Code. 3/0 - (200 Amps)- Service entrance and feeder cable 1/0 (150 Amps) - Service entrance and feeder cable 2 Gauge (95 Amps) - Large water heater elements 4 Gauge (70 Amps) - Electric furnaces, large electric heaters 6 Gauge (55 Amps) - Furnaces, cooktops and electric ranges 10 These runs must be sized for full generator output and must meet wiring independence requirements. Type MC cable shall be permitted as follows: Type MC cable shall be permitted as follows: (1) For services, feeders, and branch circuits. 2023 National Electrical Code Chapter 3 Wiring Methods and Materials Article 330 Metal-Clad Cable: Type MC 330. Many distribution systems operate using a radial feeder system. rcrrkwpscoaywqbdmvehhgzfrctycvveisrlrgxytaory
