ANSI weatherproof receptacle plan symbol
US plan symbol for an outdoor or damp-location receptacle, drawn as a duplex receptacle with a WP subscript.
In plain English
What does ANSI weatherproof receptacle plan mean?
Outdoor receptacles in US practice are drawn with the duplex receptacle form plus WP. The tag tells the installer to fit a weatherproof cover, and for many outdoor locations an in-use cover that stays weatherproof while a cord is plugged in.
A simple example
WP receptacles are typically also GFCI protected, so plans often carry both tags or a general note. Mounting height above grade and proximity to pools or fountains are common notes next to the symbol. WP does not specify the enclosure rating or whether an in-use cover is required. The specification must state these.
What the drawings help you do
Read WP and GFCI tags together. Check for an in-use cover requirement. The IEC weatherproof outlet uses an IP tag; the US form uses WP on the duplex receptacle symbol.

What it represents
Outdoor receptacles in US practice are drawn with the duplex receptacle form plus WP. The tag tells the installer to fit a weatherproof cover, and for many outdoor locations an in-use cover that stays weatherproof while a cord is plugged in.
WP receptacles are typically also GFCI protected, so plans often carry both tags or a general note. Mounting height above grade and proximity to pools or fountains are common notes next to the symbol. WP does not specify the enclosure rating or whether an in-use cover is required. The specification must state these.
How to read it
- Read WP and GFCI tags together.
- Check for an in-use cover requirement.
Information to show or reference
- Specify cover type.
- Confirm ground-fault protection.
- State height above grade.
A distinction that matters
The IEC weatherproof outlet uses an IP tag; the US form uses WP on the duplex receptacle symbol.
