I have always understood that main electrical panels are no longer (if ever) allowed to be placed in a laundry room because of the high moisture content. What about the Sub-Panel? Wouldn’t the concern be the same?
I am not aware of any NEC provision that would disallow the main or the sub to be in a laundry room.
Bathrooms, clothes closets and over the steps of the stairs (except for landings) are the three locations that are no-no’s, but everything else is OK as far as I know.
The NEC doesn’t address “laundry rooms”, so the installation of any panelboard requires following the normal listing/labeling, including proximity to sinks, working clearances, etc.
It does not matter whether a panel is a “main” (service) or “sub” (distribution) panel. Any rule regarding location applies to both.
Right… sub or main (or, to name them properly, service panel or a remote distribution panel) may be located in any place other than over stairs, in a bathroom or in a clothes closet.
However, even in a permissible location, the clearances per 110.26 (A)(2) must be maintained. To illustrate that requirement, one must be able to put an empty refrigerator box in front of a breaker panel.
There are no other limitations that I know of.
I’m curious as to why a laundry room would have a high moisture content?
I’m curious where the proximity to sinks come into play. Nothing in Art. 408 about sinks…
Burst washer hose?
What about outside??? Lots of panels outside here and they are suceptible to moisture.
Certainly some basements, sheds and garages have a higher or equal degree of moisture than any laundry room and panels are permitted in those locations.
I was using that as an example of something obstructing the clear space, since the OP asked about “laundry rooms”.
Ok…was not clear;)
How about in a Boathouse. This panel was a little frosty.
Thanks for the education ya’ll!
