Primary Marine Wire

What is Primary Marine Wire?

Primary Marine Wire, commonly called primary wire or boat wire, is electrical wire designed for use in the harsh marine environment. This means it is built from tough corrosion resistant materials, has a strong insulating jacket, follows certain guidelines such as UL (Underwriters Laboratory), and follows a color code standard.

"it is built from tough corrosion resistant materials, has a strong insulating jacket, follows certain guidelines such as UL, and follows a color code standard."

Think about it. Not all wire is created equal. Each type of wire (marine, home, solar, speaker, etc.) is designed, manufactured, and used with a specific purpose in mind. Using just any type of wire in a marine environment could lead to disastrous results. Primary Marine Wire is the only wire designed, built, and suitable to handle the toughest marine conditions. Can you use other types of wire in your boat? Sure, but many experts strongly recommend against it. To get the best results possible, you should only use the proper materials that are designed for environment the at hand.

How is it manufactured?

Pacer Group Primary Marine Wire is manufactured in house in Sarasota, FL USA from Type III Class K copper which is chosen for its high conductivity which is higher than other commonly used types of conductors. Next, this high-quality copper is tinned for several reasons.

Tinned copper offers an added layer of corrosion resistance making Pacer Group’s Primary Marine Wire even more durable in a marine environment. Additionally, tinning copper does not significantly decrease conductivity when compared to bare copper. So, tinning the copper keeps it just as conductive and more resistant, which in turn, makes it ideal for use in the marine environment.

So now that we’ve established that we use high-grade copper, which is then tinned, what type of wire do we use? When manufacturing our Primary Marine Wire, we only use stranded wire. Why? Finely stranded wire provides unbeatable flexibility which makes it ideal for routing. Now you may think flexibility is not very important as once the wire is installed it doesn’t go anywhere, but there are two problems with that idea. First, when routing the wires initially, you will need to bend and angle the wires likely through tight spaces. Using a primary wire that doesn't offer extreme flexibility can lead to a host of issues, initially and down the road. Secondly, a marine vessel is under constant vibration. That means every second you’re on your boat your wires are under considerable stress. A marine wire that is extremely flexible is likely to handle that vibration much better than a less flexible wire. In the end, it boils down to how rugged you want your boat to be and how often you want to deal with maintaining or changing out your wires.

How do you know which color insulation to choose?

The point of coloring the insulation is so that its intended usage is made obvious to anyone working on your boat. This makes the process of maintenance, repair or replacement easier by visually identifying the wire. Let’s say you need to replace the wire running to the water temperature gauge. Then, if your electrical system was wired correctly, all you need to do is find the tan wire and replace it. Below you will find a simple chart showing the most common color codes that are used in boat wiring. Hopefully, now you understand why having such a method in place is important. Can you imagine tracing a wire across the length of a boat. This methodology saves on time, repair costs, and ensures anyone can work on your system.

How do you terminate Primary Marine Wire?

Terminating our Primary Marine Wire is easier than many people would guess. Our flexible proprietary insulation, while extremely tough and durable, is surprisingly easy to cut. This makes the process of stripping our Primary Marine Wire a simple task. Once you have the proper tool, all you need to do is measure the correct amount of insulation to remove based on the terminal needed and the application at hand. After you have removed the insulation, you will have access to the tinned copper conductors. Now, the next few steps may vary depending on the terminals or connectors you are using, but the basic idea is to have the upper grip of the terminal grab onto the tinned copper conductors and the lower grip of the terminal hold on to the insulation of of the wire. This dual grip on the wire gives strength to the connection point and reduces stress giving a longer life to the connection. This idea, coupled with the high levels of resistance that our Primary Marine Wire carries make it the ideal choice for harsh environments.

What types of resistances does our Primary Marine Wire offer?

Our Primary Marine Wire is designed and manufactured to be resistant to a range of conditions such as; acid, oil, alkali, moisture, abrasion, gasoline, and flame. What good is marine wire if it can’t handle the marine environment? We know that our customers and their families count on our wire to not only perform its function, but to last. That’s why we took every step to make our wire as resistant as possible. This way, you know if it’s Pacer Group wire you have one less thing to worry about. That's because this wire is built to last, even in the harshest conditions.
