B-LINE DT224URKPS – Frequently Asked Questions
1) Can the Eaton DT224URKPS double-throw switch be mounted outdoors on an exterior wall?
Yes. The DT224URKPS comes in a NEMA 3R enclosure made of painted galvanized steel and rated rainproof, so it is built for outdoor wall mounting or any wet exterior location. Plan the mounting surface for the size and mass: it measures 37.38 in by 19.56 in by 11.25 in and weighs 80 lb, so it is a two-person set on unistrut or solid backing, not a single-hand hang.
2) Will the DT224URKPS work as a manual generator transfer switch for a 200A residential service?
That is the job a double-throw switch does: it lets one load be fed from either of two sources, utility or generator, with no chance of both at once. The DT224URKPS is rated 200A at 240 Vac (250 Vdc) and is two-pole, two-wire, which suits a single-phase 240V service. For service entrance duty it has to have a neutral kit installed; without that kit it is not suitable for service entrance use.
3) Do I need to order anything separately with the Eaton DT224URKPS?
Two things to settle on the order. The switch is non-fusible, so overcurrent protection has to come from upstream breakers or fuses elsewhere in the system, not from this enclosure. And if you are using it at the service entrance, a neutral kit has to be installed to make it suitable for that application. Order the neutral kit alongside it rather than discovering it at rough-in.
4) Can I use this Eaton double-throw switch on a 480V three-phase service?
No. The DT224URKPS is rated 240 Vac and 250 Vdc, and it is a two-pole, two-wire switch. That covers single-phase 120/240V work only. A 480V three-phase feeder needs a three-pole switch rated 600V, so this one should not be specified for it.
5) Is the DT224URKPS fusible or non-fusible?
Non-fusible. The DT224URKPS switches 200A at 240 Vac without any internal fuse provision, so it isolates and transfers only. If your design calls for local fusing at the disconnect, this is the wrong version and you want a fusible double-throw switch in the same amperage.
6) What is the difference between a general duty and a heavy duty safety switch, and which is this?
The DT224URKPS is a general duty switch, which is the class intended for residential and light commercial service where switching is infrequent and the system is 240V or less. Heavy duty switches are built for industrial service, higher voltages, and frequent operation. If the application is a farm, a shop, or a house generator changeover at 240V, general duty is the right class. For a plant floor with daily switching or a 600V system, step up to heavy duty.
7) How much clearance and what kind of support do I need to install a 200A double-throw safety switch outdoors?
Size the wall first. The DT224URKPS is 37.38 in tall, 19.56 in wide, and 11.25 in deep, and it weighs 80 lb, so it wants solid blocking, unistrut, or a strut rack rather than siding alone. The 11.25 in depth also matters where the switch sits beside a meter socket or in a narrow side yard, since the operating handle swings on the enclosure face.
8) Will this switch feed my whole 200-amp panel, or just a few circuits?
It is rated for the full 200A at 240 Vac, so it can sit ahead of a complete 200-amp single-phase service and transfer the entire panel between two sources. That is the point of buying at 200A rather than a small emergency-circuits-only transfer panel. For the service entrance position, the neutral kit has to be installed.
9) What is the exact Eaton part number for this 200A NEMA 3R double-throw switch?
The catalog number is DT224URKPS, an Eaton B-Line general duty double-throw switch: 200A, 240 Vac, two-pole two-wire, non-fusible, in a rainproof NEMA 3R painted galvanized steel enclosure. Quote that number directly when matching a spec or reordering to match existing gear on site.
