Sockets Buying Guide

 

Choosing the right sockets and outlets is essential for a safe, functional, and
convenient electrical installation. Sockets come in many types, from standard 13A
outlets for everyday appliances to specialized shaver sockets for bathrooms, USB-
integrated sockets for charging devices, and heavy-duty industrial outlets for
workshops or machinery. Factors such as location, load requirements, environment,
and extra features like switches, tamper protection, or weatherproofing must all be
considered. By selecting the correct type, rating, and fixing, you ensure your
electrical system is not only safe and compliant but also future-proofed for modern
devices and household needs.

1) Common Types of Sockets / Outlets
Type Typical Use Notes
Standard 13A Socket General power

outlets Most domestic circuits; indoor

Switched Socket Adds a local on/off

switch

Saves energy; can isolate appliances
without unplugging

Double Socket Two outlets in one

plate

Saves wall space; common in kitchens
and living rooms

USB Socket USB charging
integrated

Ideal for phones, tablets, low-power
devices

Shaver / Low-Power
Socket Bathrooms Usually 5A, isolated, compliant with

bathroom regulations

Outdoor / Weatherproof
Socket Gardens, patios IP-rated (IP44+), covers for rain

protection

Industrial / High-Current
Socket

Workshops,
machinery

16A–32A, often red or blue,
sometimes three-phase

2) Key Features to Consider
Feature Notes
Switching Individual on/off switch or switched at fuseboard
USB / Data Ports Charging speed, number of ports, combined with 13A

socket

Socket Orientation Horizontal or vertical mounting depending on wall/space
Weatherproof / IP
Rating IP44+ for outdoor use; IP65+ for wet or exposed locations
Tamper-Resistant Shuttered for child safety
Smart / Wi-Fi Sockets Remote control, energy monitoring, automation

combination Convenient for charging phones/laptops

4) Sizing & Load Considerations
 Standard 13A sockets → Rated for up to 13A per outlet (~3kW at 230V)
 Double sockets → Each outlet rated individually; ensure total load does not
exceed circuit rating
 High-current / industrial sockets → Check amperage, phase, and cable
size
 USB sockets → Rated in Amps (usually 2.1A per port for fast charging)

5) Quick Buying Tips

1. Decide on switch or unswitched → for convenience and energy saving
2. Check environment → Indoor, bathroom, or outdoor
3. IP rating → Outdoor or damp locations must be IP44+
4. Child safety → Shuttered / tamper-resistant recommended for family homes
5. Future proof → USB, smart, or combination sockets add convenience
6. Circuit rating → Don’t overload a single circuit; consider max load
