Minimum grounding wire size chart
WebIn the 2024 NEC, Section 310.15(B)(7) contained rules on calculating the conductor size for 120/240-volt, 3-wire, single-phase dwelling services and feeders. Back in the 2011 NEC, a simple table existed showing the service size on the left and the minimum size conductor required to supply the service on the right. WebSimple. You just check the NEC feeder sizing table and see that, for 200 amp service, you will need either a 2/0 AWG copper wire or 4/0 aluminum wire. For adequate feeder sizing, you have to consult the said National Electric Code (NEC) chart. You will find this chart under the NEC Article 310.12 titled ‘Single-Phase Dwelling Services and Feeders’.
