To that I will add that regardless of whether the panel can be modified or should be replaced, the work should be performed by a qualified electrical contractor.
I am putting a temporary hold on this thread. The Forum?s rules do not permitted us to provide ?how-to? assistance to a person who is not an electrician, but who appears to be planning to do electrical installation work at home.
I invite the Original Poster to send me a Private Message (click on my member name, and a pull down menu will appear), to explain the circumstances, and to let me know if I have misjudged the situation. If this is, for example, a job-related task, one assigned to you by your employer, or if you are merely trying to get the information you need in order to be able to hire a contractor, then I will reopen the thread, and post an apology for the delay and inconvenience.
