# A7 — Power Provisions Schedule
# Schema per _playbook/checklists/working-documents.md (A7).
# Sized from A4 (11 panels @ ~50 W ea) + A6 head-end + A5 edge switches.
# Per A-007 each BMS panel requires 1× 20 A 230 V 1-phase circuit (EE Contractor scope).

  notes: "Per A-007/Q-009: each BMS panel feed nominally 20A — actual draw <0.5A; oversize for inrush + maintenance. EE Contractor terminates at knife-disconnect; BMS Contractor terminates downstream. Per A-018 — power meters are HLI to existing EE meters (Modbus); no meter supply by BMS Contractor."
