Frequently Asked Questions

How do I know if I need a panel upgrade?

Common indicators include breakers that trip when multiple appliances run simultaneously, a 100-amp service in a home with significant modern load, plans to add an EV charger or central AC, or a panel brand on the recall list. A diagnostic visit in Islip Terrace, NY will give you a definitive answer with documentation.

How long does a panel upgrade take?

Most 200-amp upgrades in Islip Terrace take one to two working days, with a planned utility outage of several hours during the swap. We coordinate the utility timing as part of the project.

Can I keep the existing breakers when upgrading the panel?

Generally no. Modern panels require breakers listed for that specific panel. Reusing breakers from an older panel is a common shortcut and a common code violation.

What does the work cost?

Panel work spans a wide range depending on scope. A simple breaker replacement sits at the entry-level. A full 200-amp upgrade with new service entrance sits at the higher end. We provide written quotes after a site visit.

Do you handle the inspection coordination?

Yes. Panel upgrades in Islip Terrace typically require an inspection sign-off, and we coordinate with both the utility and the inspector as part of the project scope.
