1-15 to C7 Power Cord - 15 Foot Non-Polarized Cable
This is a common 2 pronged power cord found on household electronics. The 'figure 8' type connector is often found on CD players, DVD players, VCRs, Laptop power supplies, and more.
Q: What is the difference between the polarized and non-polarized C7 cables?
A: Each electronic device is uniquely designed and has unique power requirements. Some require polarized power and some do not. The easiest way to tell them apart is that the non-polarized version looks like a figure 8; both sides are completly round.
The polarized version has one flat edge.
Q: I'm not sure which power cable I need. Can you help?
A: The different power connectors can be confusing. We have a chart on the resources tab to help you determine which connector you need.
IEC connectors are the standard connectors as recognized by the International Electrotechical Commission. They are non-locking connectors rated up to 250 volts. The IEC standard uses a numerical approach to distinguish which is the outlet and which is the inlet. All odd numbers (C5 C13 etc.) are the outlets which plug into the even number inlet. The odd number connectors mate with the even number directly after them. For example a C13 plugs into a C14 but will not plug into a C12.

NEMA connectors are the standard connectors as recognized by the U.S. National Electrical Manufacturers Association for AC power. The standard is comprised of both locking and non-locking connectors rated up to 600 volts. The NEMA standard uses an alphabetical approach to distinguish which is the plug and which is the receptacle. The letter P designates the plug and a R designates the receptacle. For example a 5-15P will plug into a 5-15R.
