Southwire Surge Protectors Editorial Review
The Technology Research 40100 50 Amp Surge Guard Automatic Transfer Switch is a reliable replacement for old transfer switches like the Iota. It is easy to install and shouldn't pose any safety concerns as long as the generator is not running while doing so. The switch works perfectly for RVs, as it easily switches between shore power and generator power. However, if you are outside the US, it may not comply with local regulations. There are no issues with mounting the switch upside down. Overall, it is an effective and safe product that delivers what it promises.
