A: SVT jackets are thinner and more flexible and only come in 17 or 18 AWG sizes. SJT cords have twice as much insulation making them less flexible. They can be produced in gauges sizes from 10 to 18 AWG.

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.

C15	C16	Yes	10 or 15	Used for small appliances that get very hot.
C19	C20	Yes	16 or 20	2005 PowerMac Cisco, Power Supplies Ciscoo, Chassis Dell workstations.

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.
