My Brother who’s a Journeyman explains how Expansion Couplings Work, for 200 AMP Service, Thoughts?

you >> What's it do? This expands and contracts. So, over time, when sun is exposed to this, this will do this over time. Okay. See, here's a midpoint right here. When you put these in, you're supposed to install them at the midpoint. That way it's halfway. It could either go this way or it could go this way. There's people who expand them, and I've seen them before, somehow, someway, put this on back here. Oh. >> nothing, right? It has nowhere to expand to. Mhm. Always try to put it downwards so that water will flow like this, and it won't go into the fitting. If you put it this way, water could seep in here. Okay. Right? Rain goes in, you could see that crack and come in. You flip it over, there's no way water can penetrate. That's why I have this bell end coming in here. Oh. >> Very minimal. Okay, that's a great tip. I'm just I'm just watching. I'm an apprentice. So, what are you putting on? Are you gluing? How much glue are you putting on? Just a coat of primer. I go inside and out. Nice. I like to take a knot. Ah. It's nice, right? Yeah, it's good. Looks good, dude. Fresh, clean as a whistle.
