Eaton DS125H1 – Frequently Asked Questions
1) Which Eaton conduit hub size fits a 200A loadcenter, and do the H1 and H2 hubs interchange?
Eaton splits the DS hub line by loadcenter size. The H1 hubs (DS075H1 through DS200H1) fit 70-125A loadcenters, and the H2 hubs (DS200H2, DS250H2) fit 150-225A loadcenters. So for a 200A panel you want DS200H2 or DS250H2, not DS200H1, even though both carry the 2 inch trade size. The suffix is the fit, not the conduit.
2) Do I need a conduit hub on an outdoor panel, or will a regular locknut and bushing do?
On a rainproof enclosure you need the hub. A standard locknut and bushing through a knockout does not maintain the NEMA 3R rating at the entry, and the Eaton DS hub is rated NEMA 3R specifically so the conduit entry keeps the enclosure's protection against rain, sleet and ice. Inside a dry indoor panel a plain connector is fine; on any outdoor or wet-location loadcenter, the hub is what keeps the top of the can weather-tight.
3) I have a 125A outdoor loadcenter and a 1-1/4 inch service riser. Which Eaton hub do I order?
DS125H1. The 125A panel falls in the 70-125A loadcenter range that the H1 hubs cover, and the 1.25 size is the 1-1/4 inch trade size hub in that group. It is NEMA 3R, so it suits the outdoor riser entry.
4) What conduit trade sizes does the Eaton DS hub come in?
Seven hubs across two loadcenter ranges. For 70-125A loadcenters: 3/4 inch (DS075H1), 1 inch (DS100H1), 1-1/4 inch (DS125H1), 1-1/2 inch (DS150H1) and 2 inch (DS200H1). For 150-225A loadcenters: 2 inch (DS200H2) and 2-1/2 inch (DS250H2). Match the hub to your conduit run and to the panel amperage class, because the larger trade sizes above 2 inch only exist on the H2 side.
5) Will the Eaton DS conduit hub work on a safety switch, or only on a loadcenter?
Both. The DS hub mounts on main lug only and main breaker loadcenters and on circuit breaker enclosures, and it also fits general duty, heavy duty and double throw safety switches. That covers the usual service and disconnect work in one part family, so a contractor stocking hubs for panel work can use the same hubs on a disconnect.
6) Does an Eaton CH conduit hub replace the panel's top knockout plate?
The DS is a conduit/plate hub, meaning it serves as the hub and the closure plate at the entry rather than threading into an existing knockout like a raintight connector. It attaches to the enclosure to give the conduit a secure, weather-resistant termination on a NEMA 3R panel. Order it sized to the conduit and matched to the panel's amperage class.
7) Is the Eaton DS hub rated for a 200A service?
Yes, the DS hub line is rated for applications up to 200A. For a 200A loadcenter specifically, pick from the 150-225A group: DS200H2 for 2 inch conduit or DS250H2 for 2-1/2 inch.
8) I'm standardizing hubs across a multi-building property. Can one Eaton hub part cover every panel?
No single part covers a mixed fleet. Eaton breaks the DS hubs by panel amperage class first (70-125A takes the H1 hubs, 150-225A takes the H2 hubs) and then by conduit trade size, which gives seven distinct part numbers from DS075H1 up to DS250H2. Standardize by inventorying each panel's amperage and riser size, then stock the two or three DS numbers that actually recur. All of them share the NEMA 3R rating, so the weather performance is consistent across whichever ones you carry.
