The terms male power cord and female power cord may sound straightforward, but they carry significant weight in ensuring safety, performance, and compatibility across industries.
Whether you're managing data centers, industrial equipment, or commercial installations, understanding the difference between male and female power cords is essential for making the right purchasing decisions and avoiding costly or dangerous mistakes.
In this blog, A-line Cable —your reliable power cable supplier—breaks down the essentials of male vs. female power cords, and guides you in choosing the right solution for your operations.
Power cords are the lifelines of every powered system, and selecting the right connectors directly affects:
Electrical safety
Device compatibility
Energy flow and direction
Industry compliance
Understanding connector gender—male (plug) and female (socket)—helps you design more efficient systems, avoid connection errors, and maintain compliance with regional standards such as IEC or NEMA classifications.
A male power cord features exposed pins or prongs and is designed to plug into a female connector. It is often called the "plug" end of the power cord.
Has visible metal pins
Sends power into the circuit
Always plugs into a female socket
NEMA 5-15P – Common in North American household plugs
IEC C14 – Standard in computers, servers, and networking gear
Power Strips and Extension Leads – Typically begin with a male end
In data centers and server rooms, IEC C14 male power cords are widely used to connect equipment to power distribution units (PDUs). Using the wrong connector here could damage equipment or create safety hazards.
A female power cord features recessed slots or holes that receive the prongs of a male plug. It is often referred to as the "socket" or "receptacle" end.
Recessed design for safety
Receives incoming power from male end
Cannot power devices independently
NEMA 5-15R – The standard U.S. wall socket receptacle
IEC C13 – Frequently found on the back of computers, monitors, and power supplies
Extension Cord Ends – The female end connects to another device’s male plug
Most power cords are configured with one male end and one female end, forming a safe, one-way power flow system.
Feature | Male Power Cord | Power Cord Female |
Connector Type | Plug with pins/prongs | Receptacle/socket |
Typical Use | Power source connection | Power delivery/extension |
Safety Notes | Output side – higher risk if exposed | Safer if disconnected |
Common Standards | NEMA, IEC, UL, CE | NEMA, IEC, UL, CE |
Always ensure male plugs are not left exposed or live when not connected.
Only connect certified cords to prevent short circuits, overloads, or reverse current.
Never try to plug a male into another male, as this creates a shock hazard.
Choosing the right power cord is about more than just male vs. female—it’s about matching your device’s requirements and maintaining operational safety.
Understand where power originates (male) and where it should terminate (female). For example:
A server receives power through a female IEC C13
The PDU outputs power via a male IEC C14
IEC connectors like C13, C14, C19, C20 are common in IT and data centers.
NEMA connectors are common in North America for residential and commercial use.
Always verify compatibility with voltage and amperage requirements.
Ensure cords are certified by organizations like:
UL (Underwriters Laboratories)
SAA
VDE/TUV
CCC
A-line Cable manufactures UL-listed, SAA-approved, VDE/TUV-approved, and CCC-certified cables for industries including:
