Review: Game changer for RV!!! - Installed this 63 amp ATS (Automatic Transfer Switch) in my travel trailer to automatically transfer power from a 30 amp pedestal to my generator and my 2000 watt inverter. For those wanting to know as i could not find out anything on the internet if you unplug from a campsite pedestal and travel to a non-electric campsite and start the generator will it automatically switch from where it left off and the answer is YES! Same with the inverter no matter what input source it was on last it automatically goes to the source input. Wire size...it will take some serious size AWG wire at least 4 AWG with really nice square tunnel connectors with the screws in front. When powering on ATS from any input source there is a settable 1-600 second delay before the relay clicks in. It has several settings but I just left everything as it came out of the box and all is good. Definitely recommend.
Review: Turn off every power system - It's easy to hook up. If they have electrical pins i would use them

### ⭐⭐⭐⭐⭐ 63 AMP DUAL VOLTAGE AUTOMATIC SWITCHING
*by T***N on December 1, 2025*

Straightforward installation, dual voltage rating and 63 amps make this automatic switch a good choice. Works as described and will be used at my remote office for emergency power switching to keep essential lights communications and heat running when the grid goes down. Reasonable price too.
