On electrical drawings, what does the symbol 'WP' typically indicate next to an outlet?
Correct Answer
C) Weatherproof outlet
WP stands for weatherproof, indicating that the outlet must be protected from moisture and weather exposure. This is commonly required for exterior outlets and those in wet locations.
Why This Is the Correct Answer
WP is a standard electrical symbol abbreviation that stands for 'weatherproof' on construction drawings and electrical plans. This designation indicates that the outlet must be equipped with appropriate protection against moisture, rain, and other weather elements. Weatherproof outlets are mandatory for exterior installations and wet locations according to electrical codes. The symbol ensures that contractors install GFCI-protected outlets with proper weatherproof covers that meet code requirements for outdoor use.
Why the Other Options Are Wrong
Option A: Wire protection required
Plate cover colors are typically specified in written specifications or schedules rather than abbreviated symbols on electrical drawings, and would not commonly use 'WP' as an abbreviation.
Option B: White plate cover
Wire protection is generally indicated through different methods on electrical drawings, such as conduit specifications or raceway symbols, not through a 'WP' abbreviation next to outlet symbols.
Option D: Wall-mounted pendant light
While wall-mounted pendant lights exist, they would typically be shown with different symbols on electrical drawings, usually represented by specific lighting fixture symbols rather than outlet symbols with abbreviations.
Memory Technique
Think 'WP = Weather Protection' - both words start with 'W' and 'P' to help remember this common electrical abbreviation.
Reference Hint
Check the electrical symbols section in your construction reference manual or the electrical code book's appendix for standard abbreviations and symbols.
