Review on 🔌 SIEMENS WN2060U Non-Fused AC Disconnect: Reliable Power Disconnect Solution for Residential Applications by Noel Pilla

I noticed that the heads of some connecting screws have very little damage from being turned with a flathead screwdriver. Or rather tried to twist with a flathead screwdriver. The top left was the worst. So when I tried it with a screwdriver I couldn't get it to spin at first, luckily I wasn't impatient. I put on a magnifying glass to take a closer look. I went and found the screwdriver that fit best. The widest and thickest screwdriver blade that will fit. I could tell I wanted maximum torque and minimum backlash. It's like someone put Loctite on the screws. I managed to untie them all but ended up hurting my thumb. It seems too tight. Also the inner metal door is too tight, I could open it but it was tight and slightly curved. I think this box is a return/one time try and the manufacturing tolerances for these parts are too tight. I think if you are young and have good strong hands you can do it. Just be careful and use a screwdriver that's not too small, as you'll need all the torque you can get.
