Hello, when building an electrical panel and mounting transformers, contactors, time delays, terminal strips and etc, do you use a screw with a lock nut on the back side or is it better to use a regular nut on back side and weld the small nut to the back panel? Or do you tap the hole you make? Back panels doesn't seem to have much wall thickness to tap I think. I have also seen contactors be snap on to a special unistrut to easy remove contactors if they go bad.
The problem I see when using a screw and lock nut is when it comes time to remove a contactor is that you have to have access to the back panel. But their are going to be many wires/switches in the way so those would have to be all removed before removing the back panel plate.
What is the best way to mounting method for these electrical controllers so it's easy to remove and install back if they need replacement? Hole tapping? Using snap-connectors? Welding nut on back panel?
Any advice would be greatly appreciated.
