  • UL/cUL listed and RoHS compliant for code-compliant installations

Automotive butt splice connector

The POWER FIRST 4FRG9 is a crimp-style butt splice for 10 AWG maximum wire. It joins two conductors in automotive and general electrical work. The seamless copper barrel has a tin finish and accepts wires down to 12 AWG. It is UL and cUL listed and RoHS compliant.

Installers needing a bare crimp splice

Electricians and vehicle technicians who need a compact, uninsulated connector for 10 AWG circuits will find this part suitable. It is not for applications requiring insulated barrels, high-vibration locking features, or wire sizes larger than 10 AWG. Buyers needing sealed or heat-shrink options should look elsewhere.

Maximum wire size 10 AWG

The connector accepts a maximum wire size of 10 AWG and a minimum of 12 AWG, which is the primary specification for selecting this splice. The seamless barrel measures 0.134 in inside diameter and 0.213 in outside diameter with an overall length of 0.59 in. It is rated for 600 V and a maximum operating temperature of 302 Degrees F.

Questions about this item

What does the 10 AWG maximum wire size mean when I am crimping this connector?

It means the barrel accepts solid or stranded copper up to 10 AWG; the minimum is 12 AWG, so anything thicker than 10 AWG will not fit.

The specs say 600 V and UL/cUL listed — what does that limit in practice?

The connector is rated for circuits up to 600 volts and carries UL and cUL listings, so it meets the safety standard for that voltage level.

How much space does the 0.59 in overall length and 0.213 in barrel diameter need inside a box?

The splice measures 0.59 inches long with a 0.213 inch barrel outside diameter, so allow at least that much clearance in the enclosure.
