WebOnline Calculators and Tables to Help You Determine Proper Wire Size The Ground Conductor Size Calculator will calculate the proper ground conductor size for grounding raceways and equipment based on ampere rating or setting of automatic overcurrent protection device in circuit ahead of equipment. WebJun 29, 2005 · The 4 AWG conductor mentioned in 250.52 is describing the electrode itself, not the grounding electrode conductor. You could have 20' of 4 AWG (or larger) for the electrode and satisfy the requirement for the electrode itself. Once you have installed that, you now have an electrode and must install a grounding electrode conductor to attach to it.
