If you’re noticing decreased efficiency in your electronic systems and equipment, they may be experiencing what’s known as voltage drop. While power supply voltage drops can be damaging, understanding the basics and how to combat them can help you prevent future harm and protect your equipment. Keep reading to make sure you understand what a voltage drop is, common causes, and how to reduce the risk of voltage drops.
A supply voltage drop describes how the energy of a power supply decreases as the electrical current flows through passive elements in an electrical circuit. The potential for voltage drop increases with the length of the circuit. The further the electricity travels from the power supply, the higher the risk of voltage drop, resulting in weaker currents and decreased power.
Excessive voltage drop can be damaging and may lead to disruptions, inefficient electrical systems, and even mechanical harm. These issues can negatively impact your electrical equipment, potentially resulting in higher operating costs and decreased productivity. Understanding some of the most common sources of voltage drops can help you better prepare for and prevent damage to your electrical systems.
While small amounts of voltage drop are expected―especially for lengthy electrical circuits―monitoring for excessive voltage drop can help protect your equipment and prevent harm.
Ohm’s law describes a formula to calculate the proportional relationship between voltage, current, and resistance. The formula to calculate voltage drop is:
V = I x R
Where V represents voltage, I represents current, and R represents resistance. For further assistance in calculating voltage drop, contact a team member at Quail Electronics, Inc.
You can use various techniques to compensate for the effect of voltage drop on long circuits or where voltage levels must be accurately maintained.

IEC 60309 plugs (International Electrotechnical Commission) are internationally certified for industrial purposes. The 60309 specification identifies these plugs as compatible with high voltages and high-powered connections. However, these industrial plugs are often referred to under a different name, making shopping for them more difficult than it needs to be.
Read below to learn more about IEC 60309 plugs and how they can best serve your applications.
Also known as pin and sleeve plugs, IEC 60309 plugs feature male “pins” for plugging into corresponding sockets and are surrounded by a female “sleeve” for protection and safety. Often, the sleeve is made from impact-resistant plastic to reduce the risk of electrical shock and promote safe handling. The male and female pin and sleeve design reinforces electrical connections and makes them ideal for industrial high-voltage applications.
IEC power adapters are designed to accept IEC 60309 plugs and safely power various industrial applications. These plugs are compatible with IEC power cords and universal power strips.
If you’re in the market for IEC 60309 plugs, you may be searching for them under the popular brand name Commando. When IEC 60309 plugs began gaining worldwide popularity for industrial and high-voltage uses, various countries began adopting it and slightly changing the name for their own standards or colloquial terminology.
Just like how the Kleenex brand name took over facial tissues and the Xerox brand name took over copiers, the MK Commando brand took over IEC 60309 plugs. However, when searching for an industrial plug, the correct term is still the IEC 60309.
IEC 60309 plugs are known for their extreme strength and durability. Built to handle high voltage levels and extreme amperages, these plugs can reliably power large machinery in various industries. Additionally, these plugs can continue to provide power with complete safety even when submerged underwater. IEC 60309 plugs have an IP rating guaranteeing their ability to withstand water and foreign objects, protecting them from dirt and dust.
IEC 60309 pin and sleeve plugs can be used for a wide range of industrial applications, including but not limited to:

Wire termination refers to the end style of a power cord. The way a cable is terminated affects its applications and determines how it can be used.
In this blog, we talk about the different ways to terminate a power cord, various wire termination methods, and types of electrical terminals for creating new cable connections.
The end of a power cable determines the available wire termination methods for that specific application. The most common cord end styles for power cables are:
For standard power cords, both ends can be plugged in or unplugged, and the cord is ready to use. All internal wires are hidden, meaning wire termination is contained in the plug or connector. However, for stripped and custom power cable ends, there are different ways to terminate a cord’s exposed wires.
Stripped end power cords feature exposed wiring, where the insulation has been removed or “stripped” away from one end of the power cord. Also referred to as removed outer jacket cords or ROJ cords, the wire termination methods for these cords are permanent and result in reliable results.
Crimped wire termination is named for the crimping tool required. A contact or terminal is “crimped” to the stripped wire, forming a permanent attachment. Crimp termination is the most common type of wire termination and forms a mechanically strong, reliable connection between the power cord and the attached terminal.
Soldering wire termination is often used for direct hard-wiring applications. The stripped wires are treated with Flux and the desired contact or terminal is soldered directly to the exposed wires. Soldered wire termination is often used for simple applications or when a wire is too small for crimping tools.
Stripped and custom-end power cables use electrical terminals to create new ends for connections. Available in insulated styles, terminals come in a range of connection options:
When selecting a terminal, ensure the sizing matches your wire gauge.

While standard power cords are excellent for nearly all applications, making secure connections in angled spaces can be difficult or near impossible. When it comes to navigating tight spaces or awkward angles, angled power cords are the perfect space-saving solution.
These power cords are designed to make reliable connections without bending or damaging the plug, allowing cables to lay flush and secure. Available in numerous configurations and styles, angled power cords can be used for all types of angled-space applications.
In terms of functional specifications, angled power cords are nearly identical to their standard counterparts. The defining and obvious difference, of course, is the angle of the plug or connector. While standard power cables do not have specific angles, angled power cords have a 90° bend in one of four directions: up, down, left, or right.
Angled power cords:
Angled power cords are identified by the location of the ground pin and the direction the cord is trailing from the vantage point when connected to a power source. Right-angle power cords and left-angle power cables are among the most popular styles, although different angles are available for other needs.
North American (NEMA) cords and IEC cables are the most popular angled power cords. While the power cord angle is based on when the plug or connector is connected to a power source, NEMA and IEC cords have different specifications for naming angled power cords based on cord direction.
For NEMA cord configurations, the type of cord is based on when the power cord ground pin is facing down, or in the 6 o’clock position. The angles are determined by the position of the power cord when plugged into a power source or socket. For example, if, when looking at a wall outlet, the power equipment is plugged in with the ground pin down and the wire is trailing toward the left, it is a left-angle power cable. If the cord is trailing right, it is a right-angle power cord. The same logic applies to up and down angles.
North American angled power cords can have either NEMA to NEMA connectors or NEMA to IEC connectors. The most common type of NEMA angle power cord is a 5-15P cable. Here, we illustrate Below is a diagram all four NEMA 5-15P angled power cord configurations.
| ANGLE | NEMA 5-15P |
| UP |  |
| DOWN |  |
| LEFT |  |
| RIGHT |  |
For IEC angled power cords, the angle of the cable is determined by the ground pin facing up, or in the 12 o’clock position. For example, for a plugged-in IEC cable with the ground pin oriented upwards, if the cable trails to the left, it is a left-angle power cable. If the cord is trailing right, it is a right-angle power cord. The same logic applies to up and down angles.
IEC 60320 C13, C14, C19, and C20 cables are among the more popular styles of IEC angled power cords. The following chart displays the various configurations for IEC C13 angled power cords.
| ANGLE | IEC |
| UP |  |
| DOWN |  |
| LEFT |  |
| RIGHT |  |
Any angled power cord can be used in place of a standard cord of the same specifications. This means that these cables are excellent space-saving solutions for both consumer and commercial applications. Common uses for angled power cords include:

For electrical power cords, technicians refer to the ends as male and female. The male being the plug and the female being the receptacle or socket.
Almost every electronic device that you use in your home or office or anywhere for that matter, have ends that come in male and female components. I bet you’re a little confused as to what that means. This standard design ensures that one end fits only with the opposite gender, helping to regulate cables for power and digital signals.
The male differs from the female in that it has one or more projecting pins designed as a live contact, a neutral contact, and an optional earth (ground) contact, separated by a plastic insulator. The female has one or more sockets just big enough to accept the male pins and provides a connection point that delivers electricity once the plug is placed into it. Males can also have 2-3 conductors (pins) and females also, can have 2-3 holes (sockets).
The images below show an IEC connector that refers to the power supply inlet which is commonly seen on desktop PC power supplies.
C14 (male) power inlet, the gender of the end is defined by the pins within the hood – either 2 or 3 conductors
We all know that an electrical power cord is made up of two or more wires running side by side to form an assembly, in which the ends can connect to two devices, allowing electrical signals to flow from one device to another. However, most of us wonder what that big molded thing at the end of a connector is. That big “thing” is called a strain relief. Sounds pretty self-explanatory, right? Just like its name, a strain relief relieves a cable of stresses and tensions that could break the conductor inside or even the connection between the plug and the cable.
There are different types of strain relief too. The first one always comes molded to the jacket and part of the plug. This type of strain relief is mainly designed to avoid any damage to the conductors and separation of the plug from the cord itself.
Second, we have a type of strain relief called Cable Glands. Continue reading What is a Strain Relief?
