To it apart to see what kind of quality it was inside. I am pleasantly surprised. Top portion is made of steel but the bottom is non-magnetic in assuming nickel plated brass. Electricial separation looks pretty good.Stamped with a 32A rating, but I would never run that much current through this. I also don't trust this for in-wall or hidden installations.I plan on using for semi-permanent installations of non-critical loads of absolutely under 10A (typically under 3A). For my use case, it is perfect.
