What Is A Fuse?

Posted by Lauren on Dec 2, 2016 12:52:00 PM

What is a fuse? Simply put, it's your first line of defense against a short circuit. 

When a circuit experiences an excessive amount of current flow, fuses heat up and blow to protect the circuit from damage, such as fires. Usually, fuses are found close to the battery in order to avoid battery damage from a direct short in the cables coming off the posts. Often times you'll find one larger fuse block closer to the battery, and then have the circuit branch out further away with additional, smaller fuse blocks.

Fuses function similar to circuit breakers, except circuit breakers are often more accessible. Typically, engineering schematics will dictate when and where you'll need to use fuses versus circuit breakers.

What Is A Solenoid?

Posted by Lauren on Oct 27, 2016 7:46:00 AM

Overview

Often times when working on high amperage applications a solenoid is incorporated into the wiring system. This is due to their ability to control a large output of power with very little power input. But, what is a solenoid?

A Comparison Between Battery Cable And Welding Cable

Posted by Lauren on Sep 8, 2016 9:30:00 AM

We often hear "what's the difference between battery cable and welding cable?" That's a good question! While these types of cables appear to be quite similar by their exterior construction, they become very different beginning with the copper strands inside...and that's just the start.

What Does A Resistor Do And Why Is It Important?

Posted by Lisa on Aug 4, 2016 11:30:00 AM

Whether you are fixing your air conditioning, connecting new LED lights, or wiring a relay, you are probably working with a resistor. Resistors can be found in almost every electrical circuit, but they are often built-in to other components. So what do these hidden resistors really do? And why are they so important to the electrical circuits you use every day?

What Is Primary Wire?

Posted by Lauren on Jul 28, 2016 11:43:40 AM

What is primary wire after all? Often times when working on electrical builds, you’ll hear “primary wire” or “GPT wire” thrown around quite a bit. So, why is that? Primary wire is one of the most common types of wire to use in electrical builds – specifically in automotive or DC applications.

Why Should You Choose Painless Performance Wire Harnesses?

Posted by Megan on May 5, 2016 1:39:00 PM

Universal chassis wire harnesses by Painless Performance are the easiest preassembled harnesses to install. All preassembled wire harnesses are not made equally. Just one installation with a Painless harness and you will never use an inferior harness again.  

Advantages of choosing Painless Performance wire harnesses

Less wires to route. During the final assembly of the harness, Painless groups the wires together based on the appropriate vehicle location. Depending on the application the average harness will have 15-18 groups of wires all wire-tied together. Instead of routing over 100 individual wires, you will only have to route the groupings saving you time and effort.

What Exactly is Primary Wire?

Posted by Andrew on Jan 18, 2016 10:07:00 AM

Primary wire is primary wire, right? Not exactly true. There are different “grades” of primary wire, based on temperature ratings (voltage ratings are typically the same at 50V DC). Buy the wrong type, you could wind up melting the jacket and causing a short or electrical fire. Not good at all. So let’s go over some basics.

 

Construction

Generally, standard primary wire is the most popular, widely used and economical type of wire. The insulation jacket is normally smooth and brightly colored and is manufactured from PVC (polyvinyl chloride).

HDT – Heavy-Duty Thermoplastic and TWP – Thin wall Thermoplastic primary are also available, but I will be focused on the standard wire.

The internal copper strands of standard primary wire are bare copper (BC) and gauge size of the wire is measured to SAE standards. Stranding is often represented by 7/.0126. The first number is

Different Systems of Wire Connectors & Their Varying Benefits

Posted by Nicole on Jan 14, 2016 1:55:00 PM

Wire connectors and electrical connector systems are multi-pieced setups which are commonly used when making wiring connections in applications varying from automotive and marine to agriculture and other electrical connections. There are many different system selections to choose from and each series carries a unique set of characteristics depending on the use and application of the electrical connectors. Knowing what these different connection types, benefits, characteristics, and uses are makes creating a positive connection simple and efficient.

Choosing the Right Heat Shrink

Posted by Steve on Dec 28, 2015 10:51:00 AM

Del City offers a wide selection of heat shrink to ensure your wire and connections are protected from dirt, moisture, and corrosion. Heat Shrink is commonly used in applications where the connection is exposed to corrosive environments such as battery connections, marine panels, and trailer wiring. The heat shrink allows for the connection to be “sealed” off from salt water, road spray and debris, as well as dust and dirt.Want more details on the benefits and details of heat shrink material? Check out our post "What Is Heat Shrink?" here!

Choosing the Right Type

The most basic choice is a 2:1 single wall shrink tube. It is a good all around, general purpose product and is available on rolls as well as 4’ sticks. This style of heat shrink is most often used in general purpose applications particularly where the connection is not exposed to a lot of contaminants. In addition, this product is a UL recognized component.

The most popular option is
