Summary
Islip Town Code bars anyone from wiring or altering an electric light, heat or power installation of 50 volts or more without filing for inspection with an approved electrical inspection service, and bars connecting that wiring to any power source until the service issues a certificate of compliance.
All electrical installations shall be in accordance with the National Electrical Fire Code, except that aluminum wiring shall not be permitted on the load side of the service disconnect in dwellings, buildings or structures for which residential occupancy is a permitted use. It shall be unlawful for any person to install or cause to be installed or to alter or repair electrical wiring for light, heat or power until an application for inspection has been filed with an approved electrical inspection service.

Full Breakdown
Chapter 19, Article XXII of the Code of the Town of Islip sets the electrical permitting rule governing new wiring and alterations townwide, outside the incorporated villages. " Section 19-129B makes the inspection step mandatory: "It shall be unlawful for any person to install or cause to be installed or to alter or repair electrical wiring for light, heat or power until an application for inspection has been filed with an approved electrical inspection service. " The article covers wiring for light, heat, power and signal systems at 50 volts or more, but exempts ships, railway cars, automotive equipment and utility installations.
Under § 19-130, Chief Inspectors of an approved electrical inspection service carry out inspections and reinspections at the Town's, Chief Fire Marshal's or Chief Building Inspector's request, file written reports on defective work to those officials and the owner, and authorize the compliance certificate once wiring conforms. Section 19-131 shields the inspection service and its inspectors from civil liability for inspection or certification decisions.
Violations & Fines
Connecting or energizing wiring before an approved electrical inspection service issues a certificate of compliance is unlawful under § 19-129B, and using aluminum wiring on the load side of a residential service disconnect violates § 19-129A. Defective installations found on inspection are reported in writing to the Chief Fire Marshal, the Chief Building Inspector and the property owner or lessee, and compliance certificates are withheld until corrected.
