About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Electrical Wiring and Connecting

Low-Voltage Cable

Rated to 12 volts DC, this cable is often used in low-voltage applications such as battery and vehicle wiring and radios. Also known as GPT cable.

Fusible Link Wire

Often found in older vehicles, this fusible link wire protects a circuit in applications where you can’t use a standard fuse.

Detachable-Cord AC to DC Adapters

Couple these adapters with a cord that matches your outlet and length requirements to run DC-powered electronics.

AC to DC Adapter Cords

Plug these adapter cords into a standard outlet and they change AC voltage to DC voltage.

International AC to DC Adapter Cords

Swap the plug to match the outlet of the region you’re in instead of using separate cords for each country. These adapter cords convert AC voltage to power DC electronics.

Medical-Grade AC to DC Adapters

To run DC-powered lab and medical equipment from your outlet, add a power cord with the plug style and length you need. These adapters meet strict IEC, UL, or ANSI/AAMI standards for use with medical devices.

DC to AC Adapter Cords

Plug these cords into a vehicle socket to charge devices that run on AC voltage.

Barrel-Style DC Power Cords

Carry DC power in or out of electronic devices with these cords. All have industry standard barrel-style connections, letting you power electronics from power supplies.

Barrel-Style DC Power Cord Splitters

Send DC power to multiple electronics from one source. With industry standard barrel-style connections, these splitters are compatible with many power supplies and other devices.
