B-LINE DT228FGK – Frequently Asked Questions
1) Can the DT228FGK double-throw switch be used outdoors or in a washdown area?
No. The Eaton DT228FGK comes in a NEMA 1 painted steel enclosure, which is indoor, general-purpose only. It has no rating for rain, dust, hosedown or corrosive locations, so an outdoor generator tie or a wet mechanical yard needs a NEMA 3R or 4X enclosure instead.
2) Will a 1200A double-throw switch work on a 480V service?
No. The DT228FGK is rated 240V, two-pole, two-wire at 1200A. It is a single-phase 240V device, so a 480V three-phase service needs a 600V-rated three-pole double-throw switch, not this one.
3) Does the DT228FGK come with fuses, and what class do I order?
Fuses are not supplied. The DT228FGK is fusible without neutral and the fuse clips take Class L fuses, which is the class used above 600A. Order six Class L fuses sized to the load (two-pole double-throw means a fuse set for each throw position) rated 240V or higher at up to 1200A.
4) Is there a neutral landing in this 1200A safety switch?
No neutral is included. The DT228FGK is a fusible without neutral, two-wire configuration, so if the feeder carries a neutral you will need a separate neutral kit or an isolated neutral bar mounted elsewhere. Plan the enclosure gutter space for it.
5) What is a double-throw switch for, and do I need one instead of two disconnects?
A double-throw switch transfers a load between two sources, typically utility and generator, with a single handle that cannot sit in both positions at once. That is the reason to use the DT228FGK rather than two separate single-throw disconnects: the mechanical interlock is built in. It is a manual heavy duty device, so someone has to walk up and throw it. If you need automatic transfer on loss of power, an ATS is the right product, not this switch.
6) What is the exact part number to order this Eaton 1200A double-throw switch?
Order it as Eaton DT228FGK. That number covers the 240V, 1200A, two-pole two-wire heavy duty double-throw switch in a NEMA 1 painted steel enclosure, fusible for Class L fuses without neutral. Eaton publishes a spec sheet for the DT228FGK if your submittal package needs the drawing.
7) Is the DT228FGK heavy duty or general duty rated?
Heavy duty. The K-series DT228FGK is built for the service-entrance and industrial applications where frequent operation and higher fault duty are expected, which is what a 1200A Class L fusible transfer point calls for. General duty switches top out well below this ampacity.
