I work for a company where we bring a mobile trailer to different job sites everyday. We run two 110v plugs to the trailer. Some of our client only have 220v. I want to be able to easily hookup 110v or 220v depending on what the client has. I think the auto transformer will work for me. I’m unsure if I can wire the autotransformer to switch between 110v and 220v daily. Do you guys think the auto transformer will work?
Hi, I would wire the Auto transformer with a 110V socket on the output so on a 220 site, you can plug your 110V distribution into the Auto-transformer. On a 110 site, you just use a 110 extension lead. All this means is that you need a 220 extension lead and a 110 extension lead. No other switching is required.
