No, your boss should be the one to sign such a document since it is your boss who has more of an interest in the work than you do and he or she is the supervisor. Further, those work order sign offs are to protect the party doing the work. So if someone signs it and the work is still not complete or done improperly, then you may have put yourself, your boss or the company in a situation to pay out of pocket for additional repairs and preclude any liability on the part of the electrician actually doing the work. The best thing to do at this point is to discuss the matter with your boss and suggest how the company can test it out with the electrician there to enable everyone to witness the same thing and be on the same page.
