When were electrical panels banned from installation in bathrooms?
Tuesday, December 31, 2019
The prohibition took effect with the 1993 edition of the National Electrical Code (NEC). NEC 240.24 (D) says: “Not Located in Bathrooms - In dwelling units, dormitories, and guest rooms or guest suites, overcurrent devices, other than supplementary overcurrent protection, shall not be located in bathrooms.”
Any panel installed in a bathroom before the 1993 edition of the NEC took effect in their area (sometimes it’s several years before the latest edition is adopted) does not have to be moved. But the panel will need to be relocated when it is replaced as part of any service upgrade.
Even if the panel shown above was installed before the ban on bathroom installation took effect, it was still in violation of the requirement for a clear area for working space in front of the panel. The size of the necessary clear area has grown over the years, but it was always at least two feet.
