What type of cable is most commonly used for residential wiring in Rhode Island?

Non-metallic sheathed cable, commonly referred to as NM cable, is the most frequently used type of cable for residential wiring in Rhode Island. This cable is favored for its versatility, ease of installation, and cost-effectiveness. NM cable typically consists of two or more insulated conductors and a ground wire, all enclosed in a flexible plastic outer sheath. It is ideal for indoor use in dry locations, making it suitable for various residential applications, such as lighting and outlets.

In residential settings, NM cable is particularly advantageous because it is lightweight and easy to manipulate. Electricians often prefer this type for its compliance with the National Electric Code, allowing for efficient and safe installations. Additionally, NM cable offers excellent protection against electrical interference and reduces the risk of damage during installation.

Armored cable requires more installation effort and is generally used in locations where additional physical protection is needed, such as exposed or risky areas. High-voltage cable is not used in residential settings, as it is specifically designed for industrial applications requiring the transmission of electricity at higher voltages. Therefore, NM cable stands out as the
