Multiple socket outlet
Plan mark for a group of socket outlets on one plate, shown by a gang number or stacked outlet strokes.
In plain English
What does Multiple socket outlet mean?
A multiple socket outlet groups two, three or four outlets in one accessory or box. IEC-style plans usually draw a single outlet form with the number of outlets written beside it, or with short parallel strokes on the outlet, instead of drawing each outlet separately.
A simple example
The number is important for take-off and for load estimates. A desk position shown as a 3-gang outlet with data outlets beside it is a common office pattern; the reader should count the gang number, not the symbol, when scheduling accessories.
What the drawings help you do
The library already lists a duplex receptacle form from a schematic CAD family. This plan mark is the architectural counting form; it does not say whether each outlet is separately switched or whether they share one circuit.
This particular reference
Plan mark for a group of socket outlets on one plate, shown by a gang number or stacked outlet strokes. The duplex receptacle form in schematic libraries shows two outlets graphically; this plan mark counts outlets with a numeral.

How to read it
- Read the gang number; the symbol may look identical to a single outlet without it.
- Check whether switches are integral to each gang.
Information to show or reference
- Write the gang number on or beside the symbol.
- State switching per gang if relevant.
- Tag the circuit.
A distinction that matters
The duplex receptacle form in schematic libraries shows two outlets graphically; this plan mark counts outlets with a numeral.
