Rated for conductors from 6 AWG up to 350 KCMIL and a voltage rating of 600 volts, this connector handles a wide range of wire sizes in a single body. The Plastisol-insulated housing is abrasion resistant and chemical resistant, and it will not support combustion. Two hex screws with a 5\/16-inch hex drive secure the conductors. Licensed electricians and electrical contractors install this connector in both commercial and residential wiring applications where inline splicing or conductor reduction is required.\u003c\/p\u003e\n\u003cp\u003eThe ISR-350 is suited for wire termination scenarios where two conductors must be joined inline, particularly where conductor sizes differ between source and load. The connector ships with removable access plugs over each hex screw, maintaining insulation integrity while still allowing tool access during termination. Its compact body measures 4.47 inches in length, 1.32 inches in width, and 2.2 inches in height, making it practical in tight junction boxes, pull sections, and equipment enclosures. It is manufactured in the USA and carries UL approval for both the United States and Canada.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccepts conductors from 6 AWG minimum to 350 KCMIL maximum\u003c\/li\u003e\n  \u003cli\u003eRated 600 volts with a 90 degrees C temperature rating\u003c\/li\u003e\n  \u003cli\u003ePlastisol body is abrasion resistant, chemical resistant, and will not support combustion\u003c\/li\u003e\n  \u003cli\u003eTwo 5\/16-inch hex drive screws for secure conductor clamping\u003c\/li\u003e\n  \u003cli\u003eRemovable access plugs over hex screws maintain insulation coverage\u003c\/li\u003e\n  \u003cli\u003eUL listed for use in Canada and the United States\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inline wire termination applications using aluminum or copper-to-aluminum conductors ranging from 6 AWG to 350 KCMIL at voltages up to 600 volts.

De-energize the circuit and verify zero voltage with a meter before making any connections. Strip conductors to the required insertion depth, insert into the connector ports, and tighten hex screws with a 5\/16-inch hex key to secure the conductors. Reinstall the access plugs over the hex screws after termination to maintain the insulated rating of the connector body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Conductor Size\u003c\/strong\u003e: 6 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Conductor Size\u003c\/strong\u003e: 350 KCMIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Aluminum (Copper\/Aluminum compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Screws\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Plastisol\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Plastisol Insulated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 90 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL (Canada and US)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: POLARIS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ISR-350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"POLARIS","offers":[{"title":"Default Title","offer_id":51283933561138,"sku":"ISR-350","price":64.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279611.jpg?v=1781063567","url":"https:\/\/voomisupply.com\/products\/polaris-isr-350-inline-cable-splicer-reducer-350-kcmil","provider":"Voomi Supply","version":"1.0","type":"link"}
