Question:
Can a residential Load Center (sub-panel) be used for a commercial bathroom ? The current Load Center is a residential 100 AMP, and has no problems with its' load. It needs to be changed out because it is old and rusty.
Thank you,
JP

Answer:
Hi JP,
The NEC does not use the term "load center." It is a panel board and the Code does not differentiate between residential panel boards and commercial panel boards. Such differentiation or limitations may be provided by a manufacturer. Whether or not the panel board is installed in the bathroom is not directly stated in the question. While over current devices, other than supplementary over current protective devices, are not permitted in bathrooms of dwelling units, as indicated in 240.24(E), there is not a restriction for over current devices installed in commercial bathrooms. Section 240.32 does restrict the enclosures for over current devices from being installed in damp or wet locations unless they comply with 312.2. Perhaps if it is installed in a commercial bathroom, the rusty condition may have resulted from where it is located, something to consider if that is the case.
