After the site survey, they found that the largest single load in the backup load center, is going to be a 3 kVA electric motor with a start current of 32 Amps at 240 VAC for 3 seconds. Is the estimated size of one Encharge 10 going to be enough to comply with NEC 2017 710.15 (A) without using a soft starter? A. Yes, one Encharge 10 will comply B. One Encharge 10 is ok because NEC 2017 710.5(A) only applies to whole home backup C. No, it requires a minimum of 4 Encharge 3 to comply - answerC. No, it requires a minimum of 4 Encharge 3 to comply For partial home backup the guidelines in the Ensemble planning guide recommend the size of the energy storage system to be the largest of: -- Largest single load in the essential loads subpanel -- Result of load analysis of power, surge and reactive power For whole home backup what is added to the partial home backup list of items to extract the largest? A. No items are added, the guidelines for whole home are the same as for partial home backup B. Soft starters
