That the rated voltage/current matches your local supply (for example, Nigerian supply ~ 230 V, and socket rated for 13 A or more for typical loads).
Specifications
Voltage rating
~ 230–250 V AC, 50 Hz.
Current rating (socket / outlet)
13 A for most standard UK sockets.
Maximum power (approx.)
Up to ~ 3,000 W (13 A × ~230 V) — suitable for most household appliances.
Switch rating (where socket has switch or for light switches)
For simple switched outlets or standard light/power switches: often 13 A (or 10‑13 A, depending on design).
Standards / Compliance
BS 1363‑2 (socket-outlets standard) for sockets/outlets; plugs conform to BS 1363‑1 or updated versions of BS 1363.
Material (faceplate / housing / internal contacts)
Faceplate / cover & body often made of flame‑retardant plastic (thermoplastic, PC, PP, urea plastic, etc.) or sometimes with metal/stainless‑steel front‑plates; internal contacts typically brass or similar conductive metals.
Mounting type / Size / Form factor
Common 1‑gang socket / switch faceplate ~ 86 × 86 mm. Flush‑mounted with concealed screws is normal.
Terminals / Wiring capacity
Terminals often accommodate wiring size typical for general sockets — e.g. cables 2.5 mm² for general sockets. Some datasheets indicate compatibility with multiple wire sizes depending on circuit / load.
Contact / Safety Features
Sockets usually have built-in safety shutters (on live/neutral holes) — standard feature in UK sockets for preventing accidental insertion of objects.
Protection / Environmental rating
Typical indoor sockets/switches: IP20 (i.e. protection against solid objects >12 mm, but not water).
Temperature / Operating conditions
Often specified for normal indoor ambient conditions — e.g. −5 °C to +40 °C.
