Last company I worked for did these disconnect reconnects for a landscaping company. Never was an issue. Ended up doing quite a few. We also ran a lot of gaslines for outdoor fireplaces and bbq grills.
I see a good few of these on commercial re-roofs. Here in FL when the CU is moved for a re-roof it goes back on a nice, shiny new aluminum stand that's been engineered, approved, and inspected. Height, bracing, everything prescribed by code. No more patio blocks, 4x4's, etc. A good sized strip mall or office building might have 50+ of these things to disconnect and reinstall on stands.
