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.

## 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.

## Important distinction

The IEC weatherproof outlet uses an IP tag; the US form uses WP on the duplex receptacle symbol.
