Egc Size Chart

Egc Size Chart - Three big changes for sizing egcs in the 2020 nec. Minimum size equipment grounding conductors for grounding raceway and equipment. Use table 250.122 to find the egc based on 100 amps: The circular mil value of a 3 awg conductor is 52,620 circular mils, as provided in nec table 8, chapter 9. Take the value of 52,620 circular mils and multiply by 1.3 to come up with 68,406. Web figure 1 shows two equipment grounding conductors (egc) sized per the ampere rating or setting of the overcurrent device ahead of the raceway or equipment. Web equipment grounding conductors installed in cable trays shall meet the minimum requirements of 392.10 (b) (1) (c). Web what size egc would we need? Find the largest ocpd in the raceway: Size egc1 per cb1 and egc2 per cb2, using table 250.122 in both cases.
