Blackburn AMTS350103 3-port multitap

The Blackburn AMTS350103 is an insulated multitap connector with three ports arranged on the same side. It accepts stranded copper conductors from 10 AWG up to 350 kcmil and is also rated for aluminium and copper-clad aluminium wires. The body is made from aluminium with a black PVC insulation sleeve. Rated for 600 V maximum voltage, it suits industrial and automotive electrical distribution tasks.

Thermals noise and power draw

The connector is rated for a maximum operating temperature of 194 °F under normal load conditions. As a passive component it generates no noise and draws no power of its own. The aluminium body conducts heat away from the crimped joints while the PVC insulation maintains dielectric strength at the rated temperature. Secure hex-head tightening at 5/16 in ensures low contact resistance and stable thermal performance.

Bundled accessories and software

No accessories or software are included with this connector. The package contains only the multitap body itself, so installers must supply their own conductors, crimping tools and hex driver. Compliance with CSA 6591 and UL E9809 means the part meets recognised safety standards for use with compatible conductor types. The lack of bundled hardware keeps the focus on the connector’s core electrical function.

Questions about this item

How do I install the Blackburn AMTS350103 multitap connector and what is the common mistake?

Strip each conductor to the correct length, insert fully into all three ports on the same side, then torque the 5/16 in hex screws to spec. The step most often missed is verifying that every strand reaches the bottom of the port before tightening.

What maintenance or replacement will the Blackburn AMTS350103 need over time?

Inspect the PVC insulation and aluminum body periodically for cracking, discoloration or corrosion, especially after sustained loads near 600 V or 194 °F. Replace the connector if the hex screws no longer hold the 10 AWG to 350 kcmil conductors securely.

What limit appears first when the Blackburn AMTS350103 runs under continuous load?

The 194 °F maximum operating temperature is the first constraint under sustained current. Exceeding it degrades the PVC insulation and reduces clamping force on the aluminum or copper conductors before the 600 V rating becomes a factor.
