Hello, I just wanted to ask a question that has been bothering me. A friend of mine just bought a apartment/office in a commercial building and he wants me to replace all the outlets and switches. He just wants this done because they are very old and need replacing. I was just wondering if it is against the law to be doing this. He doesn't want anything to be changed just replaced. Also just as a note the reason he asked me to do it was because I am in my 3nd year of Electrical Engineering if that qualifies me in anyway. Any help would be greatly appreciated.
