NEMA & IEC Power Cord Types, Differences & Buying Guide

NEMA and IEC power cords have been used a million times in our lives. NEMA, namely National Electrical Manufacturing Association, is the industry group that sets standards for use in electrical products. And IEC (International Electro technical Commission) is a non-profit & non-govt organization that publishes international standards for AC interconnections between equipment. Both of them has some different variaties. This article introduces commonly used NEMA and IEC power cord types, and as well as some buying tips.

Where Thers’s Power, There’s a Power Cord

Power cord is a line cable or main cable that contains a pair of connecting couplers on either of its ends. Both ends are detachable from the electrical supply and device. It bears the burden of temporarily connecting a portable electronic appliance with the main electrical supply line and can easily and readily pass through a wall socket or an extension cord.

Power Cord Types

Just as the above image shows, the power cord assembly consists of two major parts. One is the cable plug. It is a male connector. Its use is for connecting the AC outlet to provide electricity. The other is the receptacle on the other end. Receptacle part acts as the female connector, which attaches to the equipment. There are several different types of connectors and interfaces used all over the world. The NEMA and IEC power cord types described here are the commonly used in North America.

NEMA Power Cord Types

The establishment of National Electrical Manufacturing Association (NEMA) certificates various power cord types throughout North American and other countries, ranging in amperages from 15-60, and in voltages from 125-600. Unique, non-interchangeable different plug types are created based on specific amperages or voltages.

There are many variants of the NEMA plugs available in the united states and north America countries, but NEMA 1-15-P & NEMA 5-15-P are the most common among them. NEMA type 1 consists of a round pin or prong right below the two flat prongs, while NEMA type 5 uses a third pin for grounding purposes.

NEMA 1-15-P—Two-Pole, No Ground

The NEMA 1-15-P is normally referenced as a two-wire non-grounding device that fits into a standard 110 VAC wall outlet. Rated for 125 V maximum, NEMA 1-15-P has two flat blades, just like the NEMA 5-15 plug, but has no ground pin. The female mating outlet for the 1-15-P is called a 1-15-R (R for “receptacle”). Most current versions of this plug have one blade slightly wider than the other.

NEMA 1-15-P power cord types

Ungrounded NEMA 1 plugs are still popularly used by manufacturers of small appliances and electronic devices because of the design’s low cost and compact size, and they are upward compatible with modern grounded NEMA 5 receptacles.

NEMA 5-15-P—Two-Pole with Ground Pin

The NEMA 5-15-P is a 3-prong grounded device which plugs into a standard 110 VAC wall outlet. The connector has two flat parallel blades, with a round ground pin located between and above them. The female mating outlet for the 5-15-P is called a 5-15-R (R for “receptacle”).

NEMA 5-15-P power cord types

IEC Power Cord Types

IEC power cord, either IEC 60320 or IEC 60309, is available in different combination of earthing, for temperatures and specific needs. When using these connecting couplers, the merchants just need to change the power cord that comply with these standards to achieve worldwide compatibility.

IEC 60320 Power Cord

IEC 60320 is recognized as the international standards used by most countries in the world, which specifies non-locking appliance and interconnection couplers for connecting power supply cords to electrical appliances up to 250 volts. The “320” refers to the number of the specification that describes power connectors. Different IEC 60320 power cord types ranging from C1 to C24 are specified for different combinations of current, voltage and temperature. For detailed information, please visit: How Much Do You Know about Power Cord Types?

IEC-C13-C15-C19-connectorNote: C13, C15, C19 are the most commonly used ones in data centers.

IEC 60320 C13 Vs. C15 Power Cord

Form the above image, we can easily see that IEC C15 is similar to the C13 power cord except for a notch opposite the earth in the C15 connector. In addition, IEC-C15 connectors will work in the C14 inlets however, IEC C13 connectors won’t fit into C16 inlets.

The IEC C15 connectors are specifically designed for higher temperature devices (up to 120°C), for example electric kettles, computing networking closets or server rooms, and PoE (Power over Ethernet) switches with higher wattage power supplies. While the standard IEC C13 power cord that runs everything from desktop/personal computers, monitors, printers and amplifiers to fixed-configuration switches. They are typically rated at 15A/250V (domestically) and 10A/250V (Internationally) with the temperature rating at 70°C.

How to Buy A Right One Among These NEMA & IEC Power Cord Types

It is extremely important to choose the appropriate power cord that will deliver high performance in terms of speed and durability. Following a few simple steps will help you make the right choice.

  • Identify the Correct Plug for the Country of Export

When deciding on the correct plug pattern, keep in mind that while some look similar that does not mean it is the right cord for the equipment. For example, removing a NEMA power cord from a cord set made with North American cable and replacing it with a Continental European plug (CEE 7/7 power cord) will not make the cord set acceptable for Europe.

  • Confirm the Voltage

The voltage rating for plugs in north America ranges from 100-127 to 200-240. Higher or lower amperage can mean a different plug pattern, even in the same country. It will destroy appliances if the 125 volts power cord is mistakenly inserted into a 220 volts receptacle,

  • Check the Current Rating of the Power Cord

Another specification to check is the current rating, the rating for north America are different from other countries 15, 20 and 30.

  • Choose the Plug Type, if Utilizing a Cord Set

The number of prongs in a plug varies from 2 to 5. The prongs can be oval, round, straight blade, and rectangular in shape. For North America, there are NEMA 5-15P and NEMA 5-20P. Knowledge of the current rating and voltage can help discern between the four types and choose the correct plug.

Final Words

When using power cord, it is essential to protect yourself and your tools with a proper ground system. FS.COM AC power cords e.g. IEC power cords, Locking power cords, NEMA power cords, etc. are available in optimal lengths and various colors. Power cord with one end of NEMA connector and the other end with IEC320 plug, are designed to meet multiple application environment.

SFP Port vs RJ45, Which is Good for Switch Cascading?

Gigabit switch that offering greater speeds and compatibility has gained in much momentum in the field of networking. And with the unceasing demand for more bandwidth, network will grow to the point that we need to connect several gigabit switches together. Switch cascading is one of the options to link more than one gigabit switches. But here comes the problem: should I cascade switches via a SFP port or just through standard RJ45 ports? Is there any difference in regard to the speed and distance. This is we’re gonna explore in the article.

What Is Switch Cascading?

Cascading more than one switches enables us to have multiple ports interconnecting each of the switches in the group. But they are configured and managed independently. Switches that are cascaded together should all support Spanning Tree Protocol (STP), in order to allow redundancy and to prevent loop. Generally switches of any models or from any manufacturers can be cascaded. There are two options to cascade switches, either use copper SFP (1000BASE-T SFP) and fiber SFP port or via standard RJ45 port on the Gigabit switch.

SFP Port on Gigabit Switch

SFP port enables Gigabit switches to connect to a wide variety of fiber and Ethernet cables in order to extend switching functionality throughout the network. The SFP port allows the switch to connect to fiber cables of different types and speeds via fiber SFP module, or even connect to Ethernet copper cables through copper SFP module. As hot-pluggable I/O devices, both fiber SFP and copper SFP models can be used on a wide variety of products and intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D / U on a port-by-port basis. For more details on Gigabit switch SFP port and how to use sfp ports on switch, please read What Is SFP Port of Gigabit Switch?

Cascading Switches: SFP Port vs RJ45

So, here we have literally three options to cascading two switches:

  • Connect SFP port of the two switches via fiber SFP module and fiber patch cable
  • Connect SFP port of the two switches via copper SFP module and copper network cable (Cat 5e/Cat 6)
  • Connect the built-in RJ45 ports via Cat 5e or Cat 6 network cable

sfp port fiber sfp copper sfp

For fiber SFP port vs. copper SFP (or bulit-in RJ45 ports ), the benefit of using the fiber SFP port for switch cascading is that you will have more Ethernet ports available for your end points connections. Besides, both RJ45 ports and copper SFP module use electric signal to transmit data, fiber SFP module, however, uses light signal can tolerate longer distances and is less prone to interference. The other criteria is that fiber SFP module in most Cisco SFP switches is capable of higher speeds than the normal copper ports.

While for copper SFP vs. RJ45 ports, things become far easier. As they both utilize electric signal to transfer, the two options are basically the same. Except that the copper SFP module would generate extra costs and increase installation time. So when it makes sense to use copper SFP module instead of RJ45 ports? Only for cases where you need to connect between an all-SFP distribution switch and an all-copper edge switch. The reason the switches have SFP slots is to support connecting to a fiber optic network, either to talk to other fiber optic gear or especially to connect over distances that copper transmission can’t support at gigabit speeds.

Conclusion

It is thus clear that the choice between fiber SFP vs. copper SFP vs. Rj45 port when cascading switches actually depends on your specific cabling environment, and where the cable run is going. FS.COM offers a broad range of copper and fiber optic transceivers that fully compatible with major vendors on the market, which makes us the vendor of choice for optical network components and solutions.
