Kohler RDT-200A-1Ph-Service Rated ATS-NEMA 3R

ůService-Rated 200A NEMA 3R 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 200-amp circuit-breaker box will work with a 200-amp auto switch). The service-entrance rated switch differs from the standard or open-transition switch in that it contains an internal disconnect mechanism to ensure that primary and backup electricity sources do not intermingle when standby power is employed. The open-transition switch requires installation of an external disconnect (normally provided by the electrician performing the install). If possible, consult with your electrician for model recommendations before purchasing switch. This 200-amp outdoor-mount switch can be used with these generator models: 8.5RES air-cooled, 14RESA air-cooled, 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.

    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.
