Hiring questions

Questions to ask before hiring

When is a 200 amp service upgrade needed?

A service upgrade may be considered when a load calculation, equipment condition, available breaker space, or a planned high-demand project shows that the existing system is inadequate. The correct answer depends on the property and utility service.

Does an EV charger always require a panel upgrade?

No. Available service capacity, charger output, and approved load-management options all matter. Ask the contractor to explain the load calculation and alternatives before approving a service upgrade.

How should I compare panel upgrade contractors?

Ask about utility coordination, permits, inspection, service-entrance work, meter-main scope, grounding and bonding, circuit labeling, outage duration, availability, and the total quoted price.
