Partial-Home Backup

  • Non-Backup loads (refer to design guidance for information on selecting circuits to back up)
  • If Non-backup loads are connected to the Non-Backup Lugs, Site-level metering is performed by integrated Site CTs.
  • If Non-backup loads are upstream of the Gateway, Site-level metering is performed by integrated Site CTs plus additional 100 A CTs on L1/L2 of non-backup circuit, or by remote meters at the point of interconnection.
  • The internal panelboard kit may be used for Generation breakers or Non-Backup loads.
  • Neutral-Ground Bonding Strap installed only if Gateway is Service Equipment.
