Frequently asked questions
SAE J1283 plugs, Superflex cable 4 AWG to 1/0. Shop a set or a loose plug.
What is an SAE J1283 connector?
SAE J1283 is the keyed two-pin jump start plug on heavy equipment. Polar Wire plugs are rated 500 A continuous and 2000 A intermittent for 30 seconds. The shape stops a reverse-polarity connection. The same receptacle is on the machine, so a jump is a plug, not clamps on a buried battery.
Will an SAE J1283 plug fit Caterpillar equipment?
Yes, when the machine has an SAE J1283 receptacle. That receptacle is the Cat, Komatsu, and CASE jump-start socket. Polar Wire J1283 plugs mate with it. Check the receptacle on the machine before you order. SAE J1283 is a plug standard, not a statement that Caterpillar buys from Polar Wire.
What is the difference between jump start cables and jumper cables?
The end fitting. Jumper cables clamp onto a battery post. Jump start cables end in an SAE J1283 plug that mates with a receptacle on the machine. Polar Wire jump start cables are Arctic Superflex Blue, 4 AWG to 1/0.
Plug to plug or plug to clamp?
Plug to plug when both machines have a J1283 receptacle. Plug to clamp when one end is a receptacle and the other is a battery you can reach with clamps. Cables run 4 AWG to 1/0.
Are jump start cables field serviceable?
Yes. The J1283 plug uses a set screw, so a plug comes off and goes back on in the field. 1000 A dual live jaw clamps on plug to clamp sets are bolted, not riveted. Components interchange between assemblies.
Do jump start cables carry the Limited Lifetime Warranty?
Limited Lifetime Warranty terms: store.polarwire.com/cable-warranty.
Where to buy SAE J1283 jump start cables?
Cables, 4 AWG to 1/0, are on Commercial Heavy Duty. Loose plugs, receptacles, caps, and brackets are on jump start connectors.
Do these cables work on Cat equipment?
Plugs fit Cat, Komatsu, and CASE SAE J1283 receptacles. Check the receptacle on the machine.
Will the plug fit Komatsu and CASE as well as Caterpillar?
Yes, on machines that use the SAE J1283 receptacle. Polar Wire J1283 plugs are compatible with the connectors used by Caterpillar, Komatsu, and CASE. That is the standard, not a brand-specific pinout. Check the receptacle on the machine.
