Choose the amperage rating of your circuit's overcurrent device to calculate the appropriate ground wire size based on the National Electrical Code (NEC). . Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. Using undersized wire in your solar installation can result in dangerous overheating, significant energy losses from voltage drop, and costly equipment failures. Ensure your grounding decisions are in. . Therefore, you must ground solar with the right wire sizes. Can I use 12 AWG wire for my grounding wire? (I ran out of 12 AWG wire) It's supposed to be 10 awg per 250. Check your local electrical codes. In this guide, we'll walk you through the ins and outs of solar. .
