Perfect for handling standard outlets and lighting in a garage setup.
Length of the Wire
The 100-foot coil was more than enough for my project, and it was easy to cut and strip as needed.

The Southwire Romex Brand Simpull Solid Indoor 12/2 W/G NMB Cable is a solid choice for residential wiring, particularly for powering switches and outlets. One of its key strengths is the patented SIMpull Cable Jacket, which makes installation much easier by allowing for smooth pulling and stripping of the wire. This feature can save time and effort, especially for DIY enthusiasts or electricians on the job. With a wire gauge of 12 AWG, it is suitable for moderate current capacities, generally rated for up to 20 amps, making it a versatile option for a variety of household applications.

The cable is made of copper, which is known for its excellent conductivity, ensuring efficient power transmission. Its insulation type, a combination of nylon and PVC, provides decent protection against wear and tear, although it is important to note that this wire should only be used in dry locations and above ground. This limitation might restrict its use in certain areas, particularly in wet environments or basements.

With a voltage rating of 600 volts, it meets typical residential requirements, making it a reliable choice for most indoor applications. Potential users should keep in mind that NM-B cables are not suitable for damp or wet locations, which may be a drawback for those looking to wire areas that have moisture.

In terms of length, the 100ft coil provides ample wire for many projects, but those with larger installations may need additional length or more coils. This product is ideal for homeowners looking to undertake their own wiring projects or contractors needing a reliable cable for indoor use. Just ensure to follow local electrical codes and regulations during installation for safety.

Buying Guide for the Best Electric Wire For House

Choosing the right electric wire for your house is crucial for ensuring safety, efficiency, and longevity of your electrical system. The right wire will depend on several factors including the type of appliances you have, the distance the wire needs to run, and the specific requirements of your electrical system. Understanding the key specifications will help you make an informed decision and ensure that your home's electrical system is both safe and effective.
Wire Gauge (AWG)Wire gauge refers to the thickness of the wire and is measured in American Wire Gauge (AWG). The gauge number inversely indicates the wire's diameter; a lower gauge number means a thicker wire. Thicker wires (lower AWG) can carry more current and are suitable for high-power appliances like air conditioners and electric stoves. Thinner wires (higher AWG) are used for lower power needs like lighting and outlets. Choose the wire gauge based on the current requirements of the devices it will power and the distance it needs to run, as longer distances may require thicker wires to prevent voltage drop.
Wire MaterialThe most common materials for electrical wires are copper and aluminum. Copper is highly conductive, durable, and less prone to corrosion, making it the preferred choice for most residential wiring. Aluminum is lighter and less expensive but has a higher resistance and is more prone to oxidation, which can lead to overheating. For general home wiring, copper is usually the best choice, but aluminum may be used for specific applications like service entrance cables where cost and weight are significant factors.
Insulation TypeThe insulation type of a wire determines its suitability for different environments and conditions. Common insulation types include THHN, THWN, and NM-B. THHN (Thermoplastic High Heat-resistant Nylon-coated) is suitable for dry and damp locations and can handle higher temperatures. THWN (Thermoplastic Heat and Water-resistant Nylon-coated) is similar but also suitable for wet locations. NM-B (Non-Metallic Sheathed Cable) is commonly used for indoor residential wiring. Choose the insulation type based on where the wire will be installed and the environmental conditions it will be exposed to.
Voltage RatingThe voltage rating of a wire indicates the maximum voltage it can safely carry. Common residential wires are rated for 600 volts, which is sufficient for most household applications. Ensure that the wire you choose has a voltage rating that matches or exceeds the voltage of your electrical system to prevent overheating and potential hazards.
Current Capacity (Amperage)Current capacity, or amperage, refers to the maximum amount of electrical current a wire can safely carry without overheating. This is closely related to the wire gauge; thicker wires can carry more current. For example, a 14 AWG wire is typically rated for 15 amps, while a 12 AWG wire is rated for 20 amps. Choose a wire with an amperage rating that matches or exceeds the current requirements of the devices it will power to ensure safety and efficiency.
Length of the WireThe length of the wire affects its resistance and the potential for voltage drop. Longer wires have higher resistance, which can lead to a drop in voltage and reduced performance of electrical devices. When planning your wiring, consider the distance the wire needs to run and choose a wire gauge that can handle the distance without significant voltage drop. For long runs, you may need a thicker wire to maintain proper voltage levels.
