Power Strips vs. Surge Protectors: A Comparison

When establishing electrical connections for multiple devices, one of the most important considerations is choosing between power strips and surge protectors. While there are many similarities between them—the ability to power several devices at once, the overall design and appearance, and the primary function—there are several distinct differences to understand before making your selection.

Keep reading to learn the different characteristics of universal power strips and surge protectors, as well as how to determine which is best for your needs.

What’s the Difference?

Power Strips

A power strip is an electrical unit with multiple electrical sockets enclosed in an electrically shielded case. These units are connected to a wall socket by a single power cord, increasing the number of outlets available from one socket. There are many different types of power strips, including hospital-grade, international, and North American. While these units are designed for specific applications, they do not offer any additional protection from electrical issues like voltage spikes. Power strips are generally cost-effective and excellent for standard applications.

Surge Protectors

In addition to performing the same basic functions as a universal power strip, a surge protector offers extra protection against electrical surges. Internal electrical components redirect sudden voltage spikes or excess energy to protect your equipment. Often, a surge protector will feature an illuminated indicator light, demonstrating that its protection is active. Surge protectors are typically more costly than power strips, but their added protection ensures more safety.

Choosing Between Surge Protectors and Universal Power Strips

Several factors should be considered before selecting a power strip or surge protector. Perhaps the most important consideration is the type of device being powered. A power strip is suitable for simple or low-risk applications such as lamps, chargers, and small appliances. A surge protector, however, is the better option for sensitive devices demanding protection, including desktop computers, TVs, and large appliances.

Additional considerations include:

  • Environment or area of use: A universal power strip is sufficient for stable environments, while a surge protector is ideal for areas prone to electrical instability.
  • Safety: Both power strips and surge protectors have maximum capacities for devices and voltages. Be sure not to overload your extension strips.
  • Budget and long-term goals: While universal power strips are less expensive than surge protectors, the long-term benefits of voltage protection can save you from costly repairs in the future.

The key difference between power strips and surge protectors is that power strips only provide extra outlets, while surge protectors protect those additional outlets and your devices.

How to Identify Male & Female Power Cords

The plug and receptacle ends of power cords are the connector components that make a cord function. And almost all connector components are assigned a gender: male and female. This helps easily distinguish connectors and match them for safe power flow.

Plugs are also known as the “male ends” of a cable and are responsible for delivering power, while receptacles are called the “female ends” of a cable and receive signals from a male end. Understanding and being able to identify male and female cord ends is necessary to ensure proper connections and help regulate cables for power and digital signals.

Keep reading to learn key identifying factors for male and female power cords and connectors.

Male & Female Indicators

Male Plugs

Male connectors, or plugs, have two or more exposed pins, including live, neutral, and an optional ground pin. Separated by insulation, the pins from a male plug directly connect with a female socket or inlet to create an electrical link. One easy way to identify a male connector: If it has Pins, it’s a Plug.

When selecting a power cord, make sure you’re choosing the right end connector for your needs. For IEC power cables, male power cords have even numbers (for example, C14). Male plugs on NEMA power cords are labeled with a “P” (for example, NEMA 5-15P).

Female Receptacles

Female connectors, or receptacles, have two or more sockets designed to perfectly receive a male plug from a separate cable or device. The recessed holes are necessary for creating a safe and consistent electrical link between male and female ends.

For IEC power cables, female power cords have odd numbers (for example, C13). Female receptacles on NEMA power cords are labeled with an “R” (for example, NEMA 5-15R).

Connecting & Converting Power Cords

Almost always, the cable with a permanent connection to a power source is a female power cord. This is to protect users and equipment from the live, exposed prongs on a male plug end. However, if you need to alter a connection point, additional components may be necessary.

The Importance of Plenum Cables

Plenum cables are those laid in the plenum spaces of buildings. These areas, which are the spaces used for air circulation in HVAC systems, are typically located between the structural ceiling and a drop-down ceiling, or under a raised floor. However, plenum spaces often contain very few fire barriers, making it essential to properly coat and protect any cables in the area.

That’s where plenum cables come in! But what exactly are plenum cables, and how do they work? Keep reading to learn more about plenum-rated cables, including when, where, why, and how to use them.

What Are Plenum Cables?

Plenum cables, or plenum-rated cables, are so named for their specific use in plenum spaces. What sets plenum cables apart from standard power cords is their fire-resistance design. Because plenum spaces often contain very few fire barriers, cables must be coated with a material that won’t contribute to creating or spreading flames.

Cable fire rating tests determined that PTFE (polytetrafluoroethylene) materials offered superior resistance to flames and minimized smoke generation. As such, plenum cables are coated with Teflon (PTFE), a fire-resistant coating that, in case of a fire, does not give off toxic gases or smoke as it burns. These cables have a very high fire-resistance rating from NEC guidelines and are the only cables suitable for plenum spaces and air ducts.

When to Use Plenum Cables

Many building codes only permit plenum-rated cables to be used for HVAC systems and plenum spaces. Because these areas have high rates of airflow, Teflon-coated plenum cables must be used to reduce the risk of fire.

PTFE has a high melting point and superior insulation characteristics, making it ideal for plenum spaces and high-voltage applications. In the event of a fire, these cables are excellent at stopping the spread of fire along the cord and preventing it from spreading throughout a system or building. Always use plenum-rated cables in plenum spaces and HVAC systems.

Why Use Plenum-Rated Cables?

Using the right cables for ducting systems is essential for safety. By nature, plenum spaces are at a higher risk of fire: they have minimal fire barriers, ongoing airflow, and many cables running through them. Together, these factors can create hazardous environments without proper precautions.

Plenum cables, coated in fire-resistance materials, are specifically designed to reduce the risk of fire in plenum spaces. If a fire were to occur, these cables would not emit toxic fumes or generate smoke, diminishing excessive risk to the building and occupants.

Additionally, because many building codes uphold strict standards for safety regulations, using plenum cables is essential to ensure compliance and avoid fines.

Power Cable Strain Relief

When using power cords, safety is the most important factor. In fact, many cables have built-in safety measures as extra precautions: ground pins, Auto-Lock® mechanisms, and surge protection, for starters. These components help manage the flow of electricity within the cord… but what about the cable itself? What protects the power cord from stress and damage?

Cable strain relief.

But how? What is it? How does it work? Why does it matter? We answer these questions and more below. Keep reading to learn more about cable strain relief!

Strain Relief: What Is It?

Strain relief describes the component at the base of a cable, just before the connector. This part of the cable often experiences the highest levels of stress, whether from pushing, pulling, bending, flexing, or twisting. Over time, continuous strain may cause the cord to deteriorate or break, leading to exposed wires and dangerous handling. That’s where cable strain relief comes in.

The strain relief acts as a hard shell, protecting the vulnerable portion of the cord from excessive stress. Different types of strain relief can be used depending on the style of cord and its application. However, all cable strain reliefs serve the same purpose: to protect power cords from damage.

What Are the Types of Strain Relief?

Standard Strain Relief

Standard cable strain relief components are pre-installed on the cord and are molded to the jacket and part of the plug. This style of strain relief is designed to avoid any damage to the conductors and prevent the separation of the plug from the cord.

Cable Glands

Cable glands, also known as cord grips or cable connectors, are independent fittings that must be manually installed over the connector and the cable joint. These fittings serve as sealing devices, ensuring a secure and effective enclosure where the cable meets the connector.

There are different styles of cable glands, including 90° angled snap elbows, which can be used for specific applications. These designs help minimize wire strain and prevent rubbing against sharp edges when the cord passes through the equipment panel.

Where Are Cable Glands Used?

While nearly all power cords are equipped with standard cable strain relief, cable grips are separate mechanical components that must be manually added. Cord grips are available in a wide range of materials, including:

  • Stainless steel
  • Nylon
  • Silicone
  • Nickel-plated brass
  • PVC
  • Nickel-plated aluminum

The right material for your cable gland will depend on your application. For example, stainless steel and nylon are beneficial for environments with liquid or freezing temperatures, while cords exposed to chemicals or high temperatures would benefit from PVC or nickel-plated aluminum cable glands. In these cases, not only does the cable strain relief protect the cord against damage from bending or pulling, but also against harsh operating spaces.

International Cord Regulations

Understanding international cord regulations can be difficult. Part of this is due to the cord approval process. In power cords, the plugs, wires, and connectors are approved as separate components rather than as a whole cable. They each have unique rules and standards they must follow. However, while nations are required to use the same regulations for connectors, the approval standards vary from country to country, making it challenging to understand international cord regulations.

It may sound complicated, but it doesn’t have to be! In this guide, we examine international standards, different approvals and ratings, and how to adapt cables to various international requirements. Keep reading to learn more!

International Standards and Approvals

The IEC (International Electrotechnical Commission) is the global association that sets standards for electrical technology, including power cords and cord components. All countries must follow IEC regulations, however, there are many different approval agencies for individual countries. Although IEC standard connectors and power cords are used worldwide, their approval standards vary by country.
For example, Underwriter Laboratories (UL) is a North American approval agency that determines the approved ratings for North American power cords. While approval agencies can have their own ratings, they must comply with IEC international cord standards.

IEC Regulations for Power Cords

The IEC 60799 5.2.2 states, “The rated current of the plug or plug connector shall be not less than the rated current of the connector.” This means the connector cannot have a higher rating than the plug attached. While rarely an issue for standard or domestic cords, this can create compatibility issues when trying to use specific cables internationally.

There are situations where a power cord’s plug and wire may be approved while the connector is not. For example, many international power cords do not have approval for the IEC-60320-C19 connector. In North America, the C19 connector is rated up to 20A. However, that same connector is rated at only 16A in the United Kingdom. Not only are the ratings different, but because the C19 has a higher rating than the 13A UK plug, the IEC will not approve the connector. For the connector to be approved, the cord would require a plug rated no less than 16A.

Adapting to International Standards

There are a couple of options to make your power cables compatible with international cord regulations. Familiarize yourself with the international standards of the country you’re visiting. If your cord’s connector is not approved, you can either use an adapter or choose a cord with a higher-rated plug. Using a cord that is compatible with a country’s approved standards and IEC regulations is an easy way to safely avoid preventable risks like shock, fire, or damage to devices.
