Leland,
I would say as long as you are doing permitted work, and your insurance is up to date, you'd be covered. the only con of having only liability insurance is that it does not cover workers comp, that's a seperate policy through my insurance anyway. So that being said work "alone".I'm also a stickler for not allowing anyone to touch any wiring on a job i have the permit for. make sure you spell that out.
