Panel upgrade questions before you accept a quote
Ask what condition or capacity need justifies the work, whether utility coordination is involved and what happens to existing circuits. A larger panel label alone does not establish usable service capacity.

State the reason for the project
Is the concern documented damage, lack of circuit space, an added load or a recommendation during another visit? Ask the electrician to separate these reasons. A panel replacement, service-capacity increase and addition of circuits are different scopes. Share planned EV charging, cooking, heating or other loads so the design is not based only on today’s appliance list.
Ask for capacity and condition evidence
Do not open equipment to inspect it yourself. Request the professional findings and any load assessment relevant to the proposed work. A panel’s visible spaces do not by themselves establish available electrical capacity. PNNL’s EV design resource illustrates why added loads require infrastructure assessment rather than assuming a new charger automatically needs a particular service size.

Compare the complete upgrade
Clarify which party handles utility work and which work remains within the contractor’s scope. Put access and restoration assumptions in writing.
| What you notice | What to record | Useful next step |
|---|---|---|
| Reason | Condition findings or added-load assessment | Why is this scope needed? |
| Supply coordination | Utility, permit and outage arrangements | Who schedules each step? |
| Existing circuits | Reconnection, identification and repairs | What is included or excluded? |
Plan shutdown and completion
Discuss affected occupants, medically necessary equipment and sensitive operations before an interruption is scheduled. Ask for updated labels, required inspection records and the completion checks. Review warranty and change terms. The contractor should explain both what the project improves and what unrelated conditions remain outside the scope.

Questions homeowners ask
Does an empty breaker space mean I can add any appliance?
No. Space and capacity are different questions. Ask for an assessment of the load, circuit design and supply arrangement.
Does every new EV require a panel upgrade?
No automatic rule fits every property. Capacity, charging needs and available design options need assessment before choosing the scope.
Is utility coordination included in every quote?
Do not assume so. Ask who applies, schedules any interruption, completes utility requirements and supplies final records.
