Step-by-step explanation:
In New York City, for services not rated over 600 volts, you can use Type MC cable as long as the cable is enclosed in a threaded metallic conduit. Type MC cable, also known as metal-clad cable, is a type of electrical cable that consists of multiple conductors wrapped in a corrosion-resistant metallic sheath. This cable is commonly used for indoor and outdoor applications, including wiring in commercial and residential buildings.
Using Type MC cable with a threaded metallic conduit provides an extra layer of protection for the electrical wiring, as the conduit helps to prevent damage to the cable due to physical impact or exposure to moisture and other environmental factors.
