Ideal Industries 89-203 – Frequently Asked Questions

1) What wire sizes can I land on the IDEAL 89-203 terminal strip?
The 89-203 takes copper conductors from 22 AWG up to 10 AWG, so you can mix small control and thermostat wire with heavier 10 AWG feeds on the same strip. It is copper-rated wire only.
2) How tight should I torque the screws on the IDEAL 89-203 barrier strip?
Tighten the terminal screws to 16 in.-lb. Under-torquing is the usual cause of a hot joint on a barrier strip, and over-torquing strips the #8-32 zinc-plated steel screws. Set a screwdriver-style torque driver to 16 in.-lb and re-check after the panel has run under load.
3) What size ring or spade terminals fit the IDEAL 89-203 terminal strip?
The terminal screws are #8-32, so use ring or spade lugs with a #8 stud opening. Center-to-center spacing between poles is .562 inch (14.82 mm), which limits how wide a ring tongue you can stack side by side without the lugs touching.
4) How many circuits does the IDEAL 89-203 handle?
Three. It is a 3-pole barrier strip, so you get three independent, barriered connection points, each with a screw on both sides for a line and load conductor. For a three-phase or three-wire control run that is one strip; anything wider needs a higher pole count.
5) Will a 10 AWG solid conductor land directly under the screw, or do I need a lug?
The 89-203 accepts 10 AWG copper directly at the screw, so a stripped solid or stranded 10 AWG can go under the plate without a crimp lug. On stranded wire many panel shops still crimp a #8 ring terminal, since it holds the 16 in.-lb. torque better over thermal cycling.
6) Can I use the IDEAL 89-203 barrier strip in a damp or corrosive environment?
The screws, surface plates, and optional hardware are corrosion-resistant, and the base is a rugged polyester thermoplastic rather than a phenolic. It is still an open barrier strip with no enclosure of its own, so it belongs inside a box or panel rated for the location.
7) Do I get jumpers or marking strips with the IDEAL 89-203?
The 89-203 ships as the 3-pole strip with its terminal screws and surface plates. Jumpers, mounting brackets, and marking tape are called out as optional hardware, so order those separately if your panel drawing shows bussed poles.
