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
- <p> Voltage rating</p><p> ~ 230–250 V AC, 50 Hz. </p><p> Current rating (socket / outlet)</p><p> 13 A for most standard UK sockets. </p><p> Maximum power (approx.)</p><p> Up to ~ 3,000 W (13 A × ~230 V) — suitable for most household appliances. </p><p> Switch rating (where socket has switch or for light switches)</p><p> For simple switched outlets or standard light/power switches: often 13 A (or 10‑13 A, depending on design). </p><p> Standards / Compliance</p><p> BS 1363‑2 (socket-outlets standard) for sockets/outlets; plugs conform to BS 1363‑1 or updated versions of BS 1363. </p><p> Material (faceplate / housing / internal contacts)</p><p> 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. </p><p> Mounting type / Size / Form factor</p><p> Common 1‑gang socket / switch faceplate ~ 86 × 86 mm. Flush‑mounted with concealed screws is normal. </p><p> Terminals / Wiring capacity</p><p> 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. </p><p> Contact / Safety Features</p><p> Sockets usually have built-in safety shutters (on live/neutral holes) — standard feature in UK sockets for preventing accidental insertion of objects. </p><p> Protection / Environmental rating</p><p> Typical indoor sockets/switches: IP20 (i.e. protection against solid objects >12 mm, but not water). </p><p> Temperature / Operating conditions</p><p> Often specified for normal indoor ambient conditions — e.g. −5 °C to +40 °C. </p><p> </p>
