Spade Terminal Jumper Cords


Spade Terminal × Wire Leads	Spade Terminal × Ring Terminal

Ready to install in panel boxes, switches, outlets, and other devices, these cords come with a spade terminal already attached to one end. No need to remove your mounting screw to install—just loosen it, slide the spade terminal in, then tighten the screw. These cords are made of stranded wire, which is more flexible than solid wire. They’re pliable enough to be pulled around corners and maneuvered in tight spaces.

Wire Lead Connection—Cords with wire leads carry a charge between electrical components, such as from a splice to screw terminal. They’re also known as non-grounding pigtails.

Ring Terminal Connection—Cords with a ring terminal are also known as grounding pigtails because they create a grounding connection when you fasten the screw into a metal surface, such as the inside of a junction box.

Handheld Battery Jump Starters for Large-Cell Batteries

Once fully charged, these starters store enough power to jump start a battery multiple times. All have reverse-polarity protection to prevent sparks and short circuits if the clamps touch or if they're not connected properly to a battery. They also have a USB port to charge mobile devices such as smartphones and tablets. To recharge, connect them to a USB port with the included cord.

12V Vehicle Plug—Starters with a 12-volt vehicle plug can be charged in a vehicle outlet.

2-ft. Adapter Cord—For 2,000A and 3,000A starters, use the adapter cord with the 12-volt vehicle socket to charge devices that require more power than what the USB cord delivers.

Quick-Disconnect Terminals with Wire Leads

Female

These terminals are connected to a single-conductor wire lead. The terminal connection tab is completely covered with insulation, leaving no metal exposed when mated. They slide together and pull apart with ease, so they are convenient for applications that require frequent connections. Use a crimper (not included) to install wire.
