Overloaded sockets – know the dangers

If we run out of sockets, most of us wouldn’t think twice about plugging in an extension lead – after all, that’s what they’re for. But before you load up another extender, double check that it’s safe to do so because overloading a socket comes with some very real risks which could pose a hazard in your home.

Know your socket’s limit

Sockets come with limits – in the UK they can take a maximum of 3000 watts or 13 amps (13A). In practise, this means you should plug no more than this into any one socket.

Plugging too many appliances into one extender or socket can overload it, which in the worst-case scenario, could result in a fire. So, even if your plug extender comes with four, six or even eight sockets, it doesn’t always mean it’s safe (or sensible) to use every one.

Extension leads should clearly show how many amps it can take – the majority sold in the UK will take up to 13A, but some take less – so it’s important to always check.

How many watts or amps do my appliances use?

Watts are used to measure power and amps measure electrical current, but few of us know how much our everyday appliances use. Surprisingly, some of the smallest household items consume the most power – for instance a hairdryer and kettle use 10 amps/2200 watts and 13 amps/3000 watts respectively, while a TV uses just 0.5 amps and 120 watts.

Electrical items should always show how many amps or watts they use – either marked on the items themselves or set out within the manufacturer’s guidelines. If you’re not sure about how much power some of your appliances use, this list of commonly used items and their ratings by the charity Electrical Safety First, is a great place to start.

Stay safe – tips on how to avoid overloading sockets

Overloading sockets is an easy thing to do but the consequences can be devastating, here are our tips on keeping your sockets safe:

  • If you’re using an extension lead, always check the maximum number of amps it can take.
  • Don’t simply plug in another appliance – be mindful of what you’re plugging in. Electrical Safety First also have an overload calculator where you can see the total amps and watts used by different everyday devices in various combinations.
  • Block style extenders that plug directly into the wall socket put extra strain on your electrics so try to avoid these and choose the long multi-way extension leads instead.
  • If you find yourself constantly needing to use an extension lead, it could be worth asking a qualified electrician to install extra wall sockets.
  • Keep an eye out for frayed wires or scorch marks around sockets, plugs or appliances.

Of course, it also goes without saying, that if you notice sparks or smell burning, you should unplug your appliances if it is safe to do so or cut power to those circuits.
