Define the project outcome
State which EV, heating, suite or appliance loads must operate and when before choosing equipment.
Capacity-path matrix
Compare control-based management and service-upgrade paths by goal, evidence, compatibility, future loads, approvals and proposal detail.
Decision file
State which EV, heating, suite or appliance loads must operate and when before choosing equipment.
Use a qualified load calculation and actual service information; avoid treating 200 A as a default target.
Record monitored loads, priority, control logic, communications, fail state, user impact and listed compatibility.
List panel, service, meter, conductors, utility, outage, access and restoration components.
Compare how each option supports the documented project queue and what changes would require reassessment.
Assign contractor verification, permit, inspection, utility, City or building and closeout responsibilities.
Define the loads and operating outcome first, then compare verified paths. Record why each proposed rating or management strategy addresses the accepted calculation instead of treating a familiar service size as automatically necessary.
Document measured or controlled loads, priorities, charger interaction, communications, fail state, user impact, settings and exact equipment compatibility. Ask how commissioning proves the intended behaviour and how settings remain available to future owners.
List service equipment, conductors, meter work, utility design, customer prerequisites, outage, access, trenching and restoration. Compare how the route affects suite, strata or renovation sequencing and what remains excluded.
Test management and service options against the same EV, heating, suite and appliance sequence. Record controlled circuits, priorities, communications, fail state, settings, user effects and exact compatibility for management; record panel, service, meter, conductors, utility work, outage, access and restoration for upgrade. Add permits, inspections, maintenance and future reassessment to both. The board should explain the accepted choice from qualified evidence without treating 200 amperes as a default goal or claiming a control device universally avoids utility work. Before choosing, review both scenarios with the qualified electrical reviewer and the owner’s real operating priorities. Record accepted inconvenience, maintenance, outage and future-expansion limits as explicit decision criteria.
