Steel City WA 151 – Frequently Asked Questions
1) What does a Steel City reducing washer do in a rigid conduit run?
A reducing washer pair lets you land a smaller conduit or fitting on a larger knockout or hub. The Steel City RGD/IMC reducing washers all start from a 1-1/2 inch opening and step it down to 1/2, 3/4, 1, or 1-1/4 inch trade size, so an oversized 1-1/2 inch knockout in a box or enclosure can take a smaller raceway without changing the enclosure.
2) Which reduction sizes are offered in the Steel City 1-1/2 inch reducing washer?
Four reductions, all from 1-1/2 inch: 1-1/2 to 1/2 (WA 151), 1-1/2 to 3/4 (WA 152), 1-1/2 to 1 (WA 153), and 1-1/2 to 1-1/4 (WA 154). Pick by the trade size of the conduit or fitting you are bringing into the 1-1/2 inch opening.
3) Do I need one reducing washer or two per opening?
Reducing washers are used in pairs, one on each side of the sheet metal, so the conduit hub or connector clamps down on both faces of the 1-1/2 inch knockout. Order two per opening, matched to the same reduction, for example two WA 152 to bring 3/4 inch conduit into a 1-1/2 inch hole.
4) I have a 1-1/2 inch knockout and only 1/2 inch conduit coming in. Can I use one of these instead of a blank and a new hole?
Yes, that is the case these are made for. The 1-1/2 to 1/2 washer (WA 151) fills the oversized 1-1/2 inch knockout and gives you a 1/2 inch opening for the conduit hub, so you avoid drilling a fresh hole or relocating the enclosure.
5) Are these reducing washers for rigid and IMC conduit, or EMT?
They are designated RGD/IMC, so they are intended for rigid metal conduit and intermediate metal conduit systems. EMT connectors use their own locknut and bushing arrangement, so match the washer to a rigid or IMC hub rather than assuming it suits a set-screw or compression EMT fitting.
6) What material are the Steel City WA series reducing washers made of?
Steel. That keeps the reduction in the same metallic path as the rigid or IMC raceway and the enclosure wall, rather than introducing a non-metallic piece at the knockout.
