Find a licensed generator installer in Shelter Island, NY

Who licenses generator installers in Shelter Island

• Suffolk County Consumer Affairs licenses the electricians who hook up standby generators, and Master Electrician and Restricted Electrical are both among its license types.
• Suffolk's home improvement law excludes work in the electrical and plumbing fields, so a home improvement license alone does not cover a generator's wiring.
• Natural Gas and LP Gas are both Restricted Plumbing categories on Suffolk's restricted license application.
• Shelter Island's notice to contractors says every contractor or subcontractor working on the island, landscapers included, needs a town license.
