Review: Generac RXSC100A3 100 Amp 120/240 Single Phase NEMA 3R Smart Transfer Switch - I needed two Smart Transfer Switches to install my generator. "See my other review" I have two meters and I had to purchase an additional switch. The main Generac home generator came with a transfer switch but each meter required a switch. It's highly recommended that these units be professionally installed. My double meter installation worked perfect. These Generac products are well built and designed to function automatically as part of a total standby system. Review: NON service rated - Exactly what you think it is but this is a NON service rated model. Which means it does not come with the interior dead cover. Pic is of page 9 in the transfer switches installation instructions. So don't be mad about no interior panel! ## Features - AUTOMATIC SMART TRANSFER: Automatic power transfer between utility and standby generator for reliable home backup during outages - ELECTRICAL SPECS: 100A single-phase 120/240V open-transition design built for Generac generators using Evolution or Power Zone 200 controllers - WEATHER-RATED ENCLOSURE: NEMA 3R outdoor-rated enclosure with heavy-duty Generac contactor for durable weather-resistant performance - LOAD MANAGEMENT: Smart power management helps prevent generator overload and supports load shedding for up to 4 HVAC circuits with no extra hardware - EXPANDABLE SYSTEM: Expandable with Generac Smart Management Modules to prioritize additional loads as your backup power needs grow - WHAT'S INCLUDED: Transfer switch enclosure with integrated controller and contactor plus installation and safety documentation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077KQNZM7 | | Actuator Type | Rotary | | Best Sellers Rank | #111,186 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #63 in Outdoor Generator Transfer Switches | | Brand | Generac | | Brand Name | Generac | | Circuit Type | 4-way | | Color | No Finish | | Connectivity Protocol | X-10 | | Connector Type | Plug In | | Contact Material | Stainless Steel | | Contact Type | Normally Closed | | Control Method | Voice | | Controller Type | Non-Service Rated | | Current Rating | 100 Amps | | Customer Reviews | 4.2 out of 5 stars 123 Reviews | | Included Components | (1) transfer switch, owner's manual, warranty sheet | | International Protection Rating | IP30 | | Item Dimensions | 14.6 x 7.09 x 20 inches | | Item Type Name | RXSC100A3 TS | | Item Weight | 18.8 Pounds | | Lower Temperature Rating | 1 Degrees Fahrenheit | | Manufacturer | Generac Guardian | | Material Type | Steel | | Model | RXSC100A3 | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Positions | 1 | | Operating Voltage | 120 Volts | | Operation Mode | ON-NONE-OFF | | Specification Met | UL | | Switch Type | Automatic | | Terminal | Screw | | UPC | 696471069600 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 1 Degrees Fahrenheit | | Wattage | 24000 watts | ## Product Details - **Operation Mode:** ON-NONE-OFF - **Current Rating:** 100 Amps - **Operating Voltage:** 120 Volts - **Contact Type:** Normally Closed - **Connector Type:** Plug In - **Brand:** Generac - **Terminal:** Screw - **Item dimensions L x W x H:** 14.6 x 7.09 x 20 inches - **Circuit Type:** 4-way - **Actuator Type:** Rotary ## Images ![100-Amp Generator Transfer Switch, Automatic Smart Transfer Switch, 120/240V Single Phase, NEMA 3R Enclosure, Load Management Ready - Image 1](https://m.media-amazon.com/images/I/61wENBpFQ5S.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Generac RXSC100A3 100 Amp 120/240 Single Phase NEMA 3R Smart Transfer Switch *by J***R on January 30, 2020* I needed two Smart Transfer Switches to install my generator.

So don't be mad about no interior panel! ### ⭐⭐⭐⭐⭐ no frills except internal battery charger *by B***N on February 15, 2023* I like the fact that there were only the switch and generator controls in the box, circuit breakers can be added by adding a separate Bracker panel, which i didn't need. ## Frequently Bought Together - Generac RXSC100A3 100 Amp Smart Transfer Switch - Seamless Power Management Solution for Generators, Solar Systems, and Standby Power Sources - Generac 7101 Battery Heater Pad for 9kW-22kW Air Cooled Standby Generators - Maintain Optimum Battery Performance, Orange - Generac 7102 Oil Heater Kit for 9kW - 22kW Air Cooled Standby Generators , Orange --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/69910086-100-amp-generator-transfer-switch-automatic-smart-transfer-switch-120](https://www.desertcart.be/products/69910086-100-amp-generator-transfer-switch-automatic-smart-transfer-switch-120) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-28*
