I had the gen. serviced Monday and my husband was supposed to ask the tech. but he forgot, hence the forum. I am most comfortable with the 20 amp duplex suggestion. All I need is a fan and a TV to find out what I happening in the world and maybe when we will get our electricity back. We have about 40K miles on this tt, I love it and want to use it a few more times. Happy trails.commercial generator hook up to TTJust got my electric back a few days ago due to Irma. Next time around I want to hook my small 30 Amp TT up to my commercial gen. Briggs and Stratton 5550 after the storm. The gen has a locking 120/240 Volt AC, 30 Amp locking receptacle. My other choice is a 120 volts AC, 20 Amp Duplex. My tt is definitely 30 Amp. Looking around online I have seen many comments about NOT hooking up to a 120/240 system. So what do I use? I do not want to blow up my electrical system. My other question is: My B&S inst. say to have the locking recp. in place before starting the gen. That would mean my camper would be open or "on" when the gen starts. I know that isn't good. I purchased an adaptor for the tt pig to the gen. Is it safe to plug in the locking adaptor first, start the gen, and then plug in the tt? All thoughts are welcome. No way can I afford a RV gen.
