What's the history, here?
It sounds like a utility worker disconnected the drop at your service entrance, and insulated the conductors. He should have left you with enough clear space for you to make repairs to your structure, and the service conduit.
I'd rather see that sort of thing affixed to a temporary stake, pounded into the ground at some remove from the structure. But it's only 240 Volts split-phase (U.S.): this is not some random wire down from a pole (which might be as high as 28,000 Volts).
Don't touch the wire bundle. But you should otherwise be able to make repairs to your property. It's not going to send a lightning bolt at you. If the utility worker did not leave you enough space to access your work area, call them back.
Yeah, people are going to object to this answer.
