Introduction to the Type of Nema Cords
Used for Lighting Fixtures
For all those who are unaware, “NEMA” is an abbreviation of
National Electrical Manufacturer’s Association. It is an an
association of electrical equipment and medical imaging
manufacturers and its mission is to build and and promote safe
electrical standards as well as products.
If a plug is labelled “NEMA”, you can consider it to be an industry
standard for safety. NEMA offers a wide array of plugs. But when it
comes to lighting fixtures for industrial and commercial purposes,
there are several confusions as to which type of NEMA power Cord
should be used for what purpose.The basic functionality of these
power plugs is to ensure proper connection for different electrical
equipment and curb the risk of accidents.
NEMA power are used domestic AC electrical appliances most in
North America and other countries which follow the NEMA
standards. SF Cable is a leading retailers of cables and cords online
and stocks a wide variety of NEMA power cords as well.

The most commonly used NEMA power plugs which connect
lighting fixtures to the receptacles. These power plugs are covered
by ANSI/NEMA WD-6 standard which is set by National Electrical
Manufacturers Association, abbreviated as NEMA.
Specifications About NEMA Power Power Cords
The wiring devices standardized by NEMA have a current rating of
15 to 60 amps, and voltage rating of 125 to 600 volts. This
standardization is done based on orientation, shapes and blade
widths. NEMA Plugs ensure that the equipment needing a
particular voltage and current is not plugged into a wrong electrical
Usually 15 and 20 amp NEMA plugs with both straight-blade and
twist-lock varieties are used for with lighting fixtures. Here’s a
breakdown to each of these power plugs and their features.
NEMA 5-15
Receptacle used: 125 V
Plug: 15A
NEMA 5-15 is used with 120V lighting system. It is a standard
grounded straight blade plug used in North America, Canada and
different parts of Mexico.
NEMA L5-15
Receptacle used: 125V
Plug: 15A
NEMA L5-15 is a twist-lock version of 120V plug. Such plugs are
commonly used to stop unintentional disconnects and with
industrial applications that likely to vibrate.
NEMA L7-15
Receptacle used: 277V
Plug: 15A
NEMA L7-15 plugs are the most popularly used twist-lock plugs
with 277V lighting systems.
NEMA L7-20
Receptacle used: 277V
Plug: 20A
The 277V lighting systems often use NEMA L7-20 plug. You can
identify the difference between 20A and 15 A by looking towards
the direction of locking ground tab. 20A points outwards whereas
15A points towards the center.
You can look into various charts and images in order to identify
different plugs and sockets. The plug usually has curved or straight
blades that stick out from the plug body. This part is considered to
be the male end of the connection. And sockets or receptacle
having corresponding slots are considered to be the female end of
