Bring the phase back up and tie it in Bring the phase back up and tie it in. Again, be sure to not come into contact with the tie.

Remove the cover-up material from the outside phase and arm.

Working from the outside (not between the phases) reach and remove the nearest phase cover-up.

Raise the neutral, remove the cover-up, and retie it Raise the neutral, remove the cover-up, and retie it. If the ground wire was taken loose, reconnect it.
