Hi Gary, >From your post, I zoomed in on the words "electrical panel", thinking you had >a product or a sub-component that is more circuit-breaker panel than A/V/ICT.
If so, I would have doubts that the North American standards would allow magnetic securement, but obviously compliance is checked by consulting the standard and the certifying engineer.

My concern is that magnets inside of an electrical panel could attract foreign objects. Loose screws, bolts or other hardware could be attracted to the magnets resulting in reduced clearances, or in the worst case, a short circuit. They could create a challenge for maintenance on the panels as extra care would be needed. I can even foresee service personnel shutting off the panel for maintenance and using the magnets as an impromptu tool holder. If they forget that a tool is held in place, there could be an electrical incident when the panel is reenergized.

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? Test T2 calls for pushing on parts in the most unfavorable direction with 10 newtons of force for 5 seconds - is this an appropriate test? The application is in stationary equipment that does not include motors, so vibration should not be a concern. I welcome advice - this is the first time I've seen such proposed construction and I don't know a standard such as 62368 to mention it.
