01

Build one equipment roadmap

Include heating and cooling, water heating, vehicle charging, cooking, laundry, hot tubs, workshops, additions, battery storage, solar preparation, and any resilience goals. Exact models are best; realistic ranges are still useful early in planning.

  • Voltage, amperage, and manufacturer requirements
  • Daily use and whether loads can be managed
  • Indoor, outdoor, garage, or detached-building locations
  • Expected purchase and installation dates
How a calculated electrical load fills a service ratingA horizontal bar representing total service capacity, divided into existing household load, an added heat pump, an added EV charger, and the small amount of headroom remaining.Calculated load against an existing service62%Existing load14%Heat pump16%EV chargerHeadroom leftAn electrician calculates this before specifying a panel or service change.
A service upgrade is decided by a calculated load, not by the number of empty breaker spaces. Adding equipment consumes capacity whether or not a slot is free.
02

Separate panel space from service capacity

Breaker space, panel condition, feeder ratings, service size, and calculated load are related but different questions. A subpanel can add distribution space without increasing the utility service. A larger panel label does not by itself create more supply capacity.

03

Plan routes and project order

Basements, attics, garages, finished walls, trenching, equipment locations, and utility work can determine the efficient order. One planned route or service project may support several future installations, while poor sequencing can reopen finishes or repeat outage and permit work.

  • Coordinate HVAC, plumbing, electrical, excavation, and utility roles
  • Clarify who supplies disconnects and equipment
  • Document permits, inspections, incentives, and deadlines
  • Preserve capacity for the projects that matter most
04

Verify current programs before purchase

Utility and Efficiency Vermont incentives can change by date, account, equipment, contractor, income, installed cost, and available funding. Verify the current terms with the responsible program before buying equipment or relying on a benefit in the budget.
