Receptacles in Damp or Wet Locations
By Mike Holt
Damp Locations. Receptacles installed outdoors
under roofed open porches, canopies, marquees, and the like (and not
subject to beating rain or water runoff or in other damp locations)
be installed in an enclosure that is weatherproof when the attachment
plug cap isn't inserted and receptacle covers are closed.
A receptacle installed within an enclosure that is weatherproof when
an attachment plug is inserted is also suitable for a damp location.
Art. 100 for the definition of "Location, Damp."
Wet Locations. All 15A and 20A, 125V and 250V receptacles
installed in a wet location must be within an enclosure that is
weatherproof even when an attachment plug is inserted. Receptacles
other than 15A or 20A, 125V or 250V installed in a wet location must
comply with (a) or (b):
Bathtub and Shower Spaces. Receptacles must not be installed
within or directly over a bathtub or shower stall. Receptacles must be
located no less than 5 feet from any spas or hot tubs [680.22(A)(1) and
680.43(A)(1)]. Hydromassage bathtubs are treated like bathtubs
- Wet location cover. A receptacle installed in a wet
where the load isn't attended while in use, must have an enclosure that
is weatherproof with the attachment plug cap inserted or removed.
- Damp location cover. A receptacle installed in a wet
for use with portable tools can have an enclosure that is weatherproof
when the attachment plug is removed.
Flush Mounting with Faceplate. The enclosure for a receptacle
installed in an outlet box that is flush-mounted on a finished surface
must be made weatherproof by a weatherproof faceplate that provides a
watertight connection between the plate and the finished surface.

Q. In a large electrical room with numerous
pieces of equipment rated at 1,200A or more, the question has arisen as
to whether panic hardware is or is not required on all of
the personnel doors. One personnel door is located 30 feet from the
nearest edge of the switchgear, which is rated at 2,000A. The other
personnel door is located 3 feet from the nearest edge of the motor
control center, which is rated at 1,600A. There is also a roll-up door
for moving equipment in and out of the room. Per the 2008 version of
NEC, which one of the following is the correct answer?
- All personnel doors must have panic hardware and open in the
direction of egress. In this example, it would include both the
- All personnel and equipment doors must have panic hardware.
- All personnel doors located within 25 feet of electrical equipment
rated 1,200A or greater must have panic hardware, and open in the
direction of egress. In this example, it would only include the
personnel door located within 3 feet of the motor control center.
- Section 110.26(C)(3) would not apply in this example because the
width of the electrical equipment is not known. This section of the
applies only to equipment that is rated 1,200A or greater, and more
6 feet in width.
