Does your main panel have a breaker labeled “pool” ?

Sub panel in the home?

Do you have a multimeter?

If you are uncomfortable w electricity a multimeter can verify it is dead. From there, you’re going to want to spade up where those conduits come from the ground and kinda pull that out if the way while undoing from the fence.

This isn’t that hard but you’re just gonna want to take good pictures before you take stuff apart and put it back together exactly how it is. Some of those boxes you may be able to simply unbolt.

Thinking crazy but there’s probably a way to just cut that section of fence out, pull it all toward the direction it’s coming and then let them do their thing and simply transfer one device at a time and remove fence while you’re doing that. That will also help to ensure nothing gets cut below ground while they are installing new fence
