Kohler RDT-400A-1Ph-Open Transition ATS-NEMA 1




…Open-Transition 400A NEMA 1 Automatic Switch







RDT-series single-phase automatic transfer switch models are built for compatibility with Kohler's residential-series RES, RESA, and RCL standby generators. T-Rex doesn't recommend utilizing a Kohler switch with the product of another manufacturer because compatibility cannot be guaranteed. The correct switch for an application will normally depend on the amp-rating of a structure's circuit-breaker box. Most of the time you will want the breaker box and automatic transfer switch to align (for instance, a 400-amp circuit-breaker box will work with a 400-amp auto switch). The open-transition switch differs from the service-entrance rated switch in that it requires an external disconnect (provided by an electrician - installed between the switch and utility feed) to ensure separation of your primary and backup electricity sources. Either switch will work fine (if possible, consult with your electrician for model recommendations before purchasing switch). This 400-amp indoor-mount auto switch will usually work best with one of these Kohler standby units: 20RESA air-cooled, 15RESA liquid-cooled, 30RESA liquid-cooled, 38RCL liquid-cooled 1Ph, 48RCL liquid-cooled 1Ph. NEMA 1 enclosures steel; NEMA 3R enclosure aluminum. Five-year warranty.

    The T-REX Free Shipping Pledge:
    The manufacturers we work with are large concerns that ship multiple items each day. This enables them to attain the best shipping rates available. T-REX passes these savings on to our customers by providing free shipping to any commercial or residential address in the continental United States. This is the T-REX pledge. We will adhere to it even when a freight carrier adds one-time or unanticipated shipping fees. Try obtaining these terms from another Internet-based generator seller.You will not find a more customer-friendly policy than ours.

    About Lift Gates:
    Typical delivery trucks are designed to be unloaded at docks, or by forklifts. In other words, they are designed to deliver to commercial locations where such options are available. By contrast, a lift gate-equipped truck lowers heavy items from the truck trailer (which can be several feet high) to the ground, using a hydraulic mechanism similar to an elevator. If your delivery will go to an address not equipped with a loading dock, and you don't have access to a forklift, then selecting the lift-gate delivery option is a convenient alternative.

    A generator from T-REX can weigh hundreds of pounds. Without access to a loading dock or forklift, unloading one safely may require several able-bodied individuals. Delivery drivers are NOT required by their companies to help customers unload.Unless you are certain that a sufficient number of helpers will be available during the delivery, we urge you to specify the lift-gate shipping option before checking out. Charge for the lift-gate is $75.00, and is NOT included in the Free-Shipping Pledge offered by T-REX. We feel, however, that it is worth the investment.

    Residential Delivery:
    You need to inform us if your delivery will be going to a residential address. Freight companies need to know this because many residential areas can't be serviced by large semi trucks. The generator will instead be loaded onto a smaller truck tailored to home deliveries. A home which serves as a place of business (regardless of the presence of company name/signage), if located in a residential area, is still considered a residential address for shipping purposes. Please select the residential delivery option if applicable. T-REX agrees to pay all additional residential delivery costs, but to do so, we must be properly informed before shipping arrangements are made.



    To select your choice of residential or commercial delivery, please see the purchase options in the Add To Cart area.
