Polaris ITO-3/0 – Frequently Asked Questions

1) Can I use the Polaris ITO-3/0 connector to splice aluminum to copper wire?
Yes. The ITO-3/0 is dual rated AL9CU, so it accepts copper and aluminum conductors, including a mix of the two in the same connector. Ampacity depends on the metal: 225A on copper, 175A on aluminum. Both ports take 3/0 AWG down to 6 AWG, and the ports ship pre-filled with oxide inhibitor so an aluminum conductor gets corrosion protection without you adding compound.
2) What wire sizes fit the Polaris ITO-3/0 two-port connector?
Each of the two ports takes 3/0 AWG through 6 AWG, copper or aluminum, and the two ports do not have to be the same size. That is what makes it a reducing splice: you can land a 3/0 feeder on one side and a 6 AWG tap on the other. Anything larger than 3/0 or smaller than 6 AWG needs a different connector body.
3) What size hex wrench and torque do I need to install a Polaris ITO-3/0?
Set screws take a 1/4 inch hex key, and maximum torque is 250 in-lbs. Use a torque wrench and hit the value: under-torquing a 3/0 conductor in an insulated connector is the usual cause of a hot splice, and over-torquing can damage the screw. No crimp tool and no heat are needed.
4) Is the Polaris ITO-3/0 connector rated for 600V and 90C conductors?
600V, with a 90C conductor temperature rating. It is UL listed to 486A/B and cULus under UL file E186991. That covers typical THHN/THWN-2 and XHHW-2 building wire at their 90C insulation rating, though your ampacity still gets sized per the NEC termination rules at the equipment.
5) Can this insulated connector be used outdoors or in an unheated building?
The ITO-3/0 carries a cold temperature rating to -45C, and the plastisol insulation is UV, abrasion, and chemical resistant, so it holds up in unheated spaces, exterior pull boxes, and cold-climate utility work. Removable plugs cap each port to keep debris and moisture off the set screws. It is still a wire connector, not an enclosure, so it goes in a box or housing rated for the location.
6) Do I still need to tape or insulate the splice after installing a Polaris ITO connector?
No. The ITO-3/0 is pre-insulated: the aluminum conductor body is encased in black plastisol rated 600V, so the finished splice needs no tape, heat shrink, or separate cover. Plug the port caps back in after torquing and the connection is done.
7) Will a Polaris ITO-3/0 connector fit inside a standard junction box or panel gutter?
The connector body measures 1.93 inches long by 1.83 inches wide by 1.83 inches high. Plan bending space for the 3/0 conductors and clearance to swing a 1/4 inch hex key on the set screws, which is usually what decides whether it fits a tight gutter rather than the body size itself.
8) Is the Polaris ITO-3/0 a tap connector or a straight splice?
Two ports, one conductor per port, so it is a straight in-line splice or a single reducing tap, not a multi-tap distribution block. If you need to break one feeder out to three or four loads, you want a connector body with more ports. The offset entry means both conductors enter from the same end rather than opposite ends, which helps when you are splicing in a shallow box or cabinet where you cannot run wire straight through.
9) Does the Polaris ITO-3/0 work with compressed or compact stranded cable?
Ports are listed for Class B and Class C stranded conductors, which covers standard building wire and utility cable stranding in the 3/0 to 6 AWG range. Solid or flexible fine-strand cable is outside what this connector is listed for.
10) Where is the Polaris ITO series connector made?
The ITO-3/0 is manufactured in the United States, which matters on jobs carrying domestic-sourcing requirements on federal, municipal, or institutional work.
