They are used in electrical work
While plastic is a versatile material used in many applications, it is not commonly used for staples. This is primarily because plastic staples are not suitable for most stapling tasks due to their lack of strength and durability compared to metal staples. However, there is one notable exception where plastic staples find utility: electrical work.
In electrical applications, plastic staples are specifically designed to secure and organize wires and cables safely. These staples are crucial for ensuring that electrical wiring is neatly arranged and securely fastened to walls, floors, or other surfaces. By using plastic staples, electricians and installers can avoid the potential hazards of using metal fasteners.
Metal staples, if they were to come into contact with live electrical wires, could conduct electricity and create a serious safety risk. Plastic, being a non-conductive material, provides an essential layer of protection in this context. Should a live wire become exposed, a plastic staple would prevent the electrical current from being conducted, reducing the risk of fires, electrical shorts, or shocks.
Plastic cable staples are typically made from durable, non-conductive plastics such as nylon or polypropylene. These materials are strong enough to securely hold wires in place while also providing the necessary electrical insulation. The staples are designed with a smooth, rounded design to avoid damaging the insulation of the wires they secure, further enhancing safety.
Additionally, plastic cable staples are often preferred for their ease of installation. They can be quickly and securely fastened using staple guns or by hand, making them convenient for electricians and DIY enthusiasts. Their flexibility also accommodates a range of wire sizes, ensuring a snug fit that prevents wires from slipping out.
In conclusion, while plastic staples may not be suitable for general stapling tasks, they offer unique benefits in electrical work. Their non-conductive properties, durability, and ease of use make them essential for safely managing wires and cables in electrical installations.

Metal staples are more common
Metal staples have been widely used for various applications, including in electrical work and upholstery. They have been a traditional choice for securing cables and wires, as well as for joining and fastening materials together. Metal staples are known for their strength and durability, making them suitable for penetrating through different types of surfaces, such as wood. However, their use also comes with certain challenges, such as the potential for the staples to fold or fly off when hammered into certain materials.
The availability and manufacturing of metal staples also play a role in their prevalence. In certain regions, such as New England, metal staples with plastic insulators are commonly used, and the proximity to manufacturers in these areas makes them readily available to suppliers and consumers. On the other hand, plastic staples may be more challenging to source in certain locations, as some supply stores may not stock them.
Additionally, metal staples offer versatility in their use. Insulated metal staples, for example, provide extra protection and can be tightened safely, making them ideal for specific applications like securing Romex neatly. Metal staples are also preferred in situations where there is a concern about pinching wires, as plastic staples are considered safer in this regard.
While plastic staples have their advantages, such as being easier to drive into certain materials and reducing the risk of shorting out NM cables, they have not reached the same level of ubiquity as metal staples. This could be due to factors such as regional availability, traditional preferences, and the specific requirements of certain tasks that favour the use of metal staples.

Insulated staples are required in some states
Plastic staples are preferred by some electrical professionals due to their ease of use and safety benefits. They are less likely to pinch wires and are easier to drive into wood compared to metal staples. Additionally, plastic staples provide extra protection and can be nailed into tighter spaces.
Insulated staples are required in certain states, such as Massachusetts, where smaller NM (non-metallic) wire sizes necessitate their use. However, this requirement may be waived if the insulated staples are installed using a listed staple gun. The use of insulated staples appears to be influenced by geographical proximity to manufacturers, as seen in Connecticut and Rhode Island, where insulated staples are commonly used despite not being mandatory.
The availability of insulated staples can vary across different states. For example, an individual from New York moving to Washington noted the difficulty in finding insulated staples in the latter state, highlighting the regional differences in supply and demand for these products.
While the use of insulated staples is mandated in specific states for smaller wire sizes, it is essential to refer to local regulations and package instructions for the correct staple usage based on wire size and other relevant factors. These regulations are in place to ensure the safe and effective use of staples in electrical work.

The availability of plastic staples varies by region, with some areas predominantly using metal staples, while others may have a harder time sourcing plastic staples. The choice between metal and plastic staples depends on the specific application, regional availability, and user preference. However, it is important to note that in certain cases, such as surgical applications, metal staples made of titanium or stainless steel are preferred due to their biocompatibility and MRI compatibility.
While metal staples have their advantages in certain situations, they can pose challenges during the application process. The hardness of the metal can make it difficult to penetrate certain materials, and the force required to drive them in may lead to issues with accuracy and control. Metal staples may also leave a more visible mark or hole in the surface, which could be undesirable in certain contexts. Additionally, the sharp edges of metal staples can pose a safety hazard during handling, requiring careful use to prevent injury.
Overall, while metal staples have their place in specific applications, they can present certain challenges that make them harder to use in certain situations.
