Gary, That's quite an idea, and I'm generally not one to squelch innovation. However, most of the safety standards I work with require that accessibility is only through use of a tool. The definition of a tool is sometimes questioned, but typically this includes keys, screwdrivers, pliers, coins, etc. If the assembly or cover is it is hand removable, then this would not be considered tool only access.
One cautionary note, I've worked with at least one safety standard that requires hazard alert labeling for static fields with magnetic flux density high enough to affect wearable, or implanted medical devices. I actually discovered a violation for a magnetically mounted ventilation filter that exceeded the limits of a static field. In that instance, the limits at 0.0 Hz for Head and Torso 200 mT (2000 G), limbs 2 T (20,000 G). If you are so inclined, you might present this to the IEC committee as a question or suggestion. -Doug Douglas E Powell Laporte, Colorado USA doug...@gmail.com LinkedIn <https://www.linkedin.com/in/coloradocomplianceguy/> On Tue, Feb 8, 2022 at 7:51 PM Gary Tornquist <05big...@gmail.com> wrote: > Hello experts, > > Can magnets be used to fasten line voltage assemblies to the inside of an > electrical panel? > > To restate my concerns, if strong enough could they be considered to > reliably maintain creepage and clearance distances, as well as not > overstressing wires terminating at the assembly? > > And how strong is strong enough?
