Yay! Thanks, Jim, that puts my mind at ease - yes, the electrician is licensed. He tried (and then some, talk about A for effort) to pull the new conduit through via the old (which was buried and also goes under part of my deck), but the new conduit wouldn't unkink/straighten out in the cold (and he has something which can warm it (?)) - plus he had to fully change out my box. Hopefully all will be well tomorrow.
