Polaris ITO-1/0 – Frequently Asked Questions

1) Can the Polaris ITO-1/0 connector splice aluminum to copper in the same connector?
Yes. The ITO-1/0 is AL9CU dual rated, so you can land copper in one port and aluminum in the other. Copper range is 1/0 through 14 AWG at 170 amps max, aluminum is 1/0 through 12 AWG at 135 amps max. Both offset entry ports ship pre-filled with oxide inhibitor, so no separate anti-oxidant compound is needed on the aluminum run.
2) What size hex wrench and what torque do I need to install a Polaris ITO-1/0 connector?
A 3/16 inch hex key drives the set screws, and the maximum torque value is 180 in-lbs. Use a torque wrench with a 3/16 hex bit rather than a plain L-key if the job is going to be inspected, since the torque value is what an inspector will ask about. Each port and set screw has a removable plug that keeps debris and moisture out until you are ready to land the conductor.
3) Is the ITO-1/0 a 2-port connector, and can I use it for a splice rather than a tap?
Two ports, one conductor each, and it is listed for splice applications. That makes it an inline splice or a single tap off a run, not a multi-tap block. If you need three or more taps off one main, you need a connector with more ports.
4) Is the Polaris ITO-1/0 rated 600V and UL listed for commercial panel work?
Rated 600V and cULus listed to UL 486A/B under file E186991, which is what a commercial or institutional inspector looks for on an insulated splice in a panel or gutter. The 600V rating covers standard 120/208 and 277/480 building distribution.
5) Can I use a Polaris ITO-1/0 connector in an unheated or outdoor location?
The plastisol insulation on the ITO-1/0 is cold temperature rated to -45C and carries a 90C upper temperature rating, with UV, abrasion and chemical resistance in the black UV coated jacket. That covers unheated mechanical rooms, exterior pull boxes, and underground or overhead distribution work. It is an insulated connector, not a submersible one, so it still belongs in an appropriate enclosure.
6) Will the ITO-1/0 fit in a tight junction box or gutter?
The connector body measures 1.68 inches long by 1.74 inches wide by 1.74 inches high, so it is a compact block, but the offset entry design means the two conductors enter at staggered positions rather than side by side. Allow room for the 3/16 hex driver to reach the set screws once the connector is in place, which is usually the limiting factor in a crowded box, not the connector footprint.
7) Does the ITO-1/0 work with compact stranded or Class C conductors?
Yes, the ITO-1/0 accepts Class B and Class C stranded conductors within its 1/0 to 14 AWG copper and 1/0 to 12 AWG aluminum ranges. Solid conductors outside those classes are not part of the stated range.
8) Do I need to add anti-oxidant compound or tape over a Polaris ITO-1/0 splice?
No on both counts. The ports arrive pre-filled with oxide inhibitor gel, and the plastisol insulation is the finished covering, so there is no taping or heat shrink step after torquing to 180 in-lbs. Pull the port plugs, land and torque the conductors, and the splice is done.
9) What is the ordering part number for the Polaris 1/0 two-port insulated connector?
Order it as ITO-1/0, the 1/0 size in the Polaris ITO Series of black UV coated pre-insulated offset entry connectors. The body is aluminum, made in the United States.
