I kinda like the idea of arc protection, but damn if they couldn't have come up with a more user friendly option... (Than make your own. If they are good, you can sell them) The floppy rubber units are easy, but then, they're so floppy, they might not be ideal... (When new, they are much stiffer) Where is that goldilocks solution? (These things are the first thing the soldiers toss away. Having said that, I once got to watch a really neat light show, when someone dropped a 19 mm wrench into and on top of, a battery.
The radiator guards don't bother me much yet, though I haven't had to work on the unit often enough to find out. (I always thought they were a PITA. One day checking oil, I had a rag wrapped around my hand to clean off the dip stick. The end of the rag got picked up by the fan slip stream and away it went. Had that rag been wrapped a tad tighter, my name here might be Lefty.) One is about half cracked off, and I was debating fixing it while I had it off last weekend. In the end I just put it back on for now. I figure it might give me a little bit of protection if the belt happened to let go when I have a door open. (One in ten hundred billion possibility. I would be much more interested in what the fan can to to things that it sucks in. Hands and parts.) If they annoy me, they're easy enough to ditch.
I'm happy that I've reached the point of complaining about minor things.
Today is hopefully the day to get the weather proof outlet setup. After that it'll be in service, and hopefully become that boring green box in the woodline that just works when needed.
Fans scare me. I almost got my hand in one, I lost some skin. That was enough for a life time. And we had a Air Con we painted a name on the side. Meat Eater. One of the D. S. repair guys, managed to get his hand vertically, (Instead of horizontally) positioned by the fan. All four of his fingers on his left had were the same, shortened length afterward.
Also, look at your slave receptacle. If the positive side is facing your face when looking at it, you need to turn it so you never get a wrench on it to touch ground. There was an emergency MWO out telling troops to do so.
