Review on ⚡ Optimized Surge Guard 40100 Transfer Switch - 50 Amp by Sean Purnomo

Switching from shore power to indoor generator takes about 45 seconds so be patient. This allows the generator to warm up in a minute. Instantly shines when it switches back to shore power when you turn off the generator. There is a clicking sound when the generator turns on, so don't think it's broken or damaged, it's normal. I can't believe I waited a year before installing this. I will never own an RV again without installing one of these.
