Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
A single outlet should ideally cater to only two to three devices, keeping total wattage within the safe usage threshold, and special caution is needed when connecting high-wattage appliances.
Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses.
13 * 230 = 2990W
That means you can connect as many devices as you like so long as their combined power is 2990W or less. That's the limit of a single UK 13A mains socket without overloading it.
A socket extension is usually rated at 10, or 13 amps – this means that the maximum rating of all the appliances your plugging in must not exceed this rating. If you do so it will still work, but could cause the plug in the wall socket to overheat, which may in turn start a fire.
When using 100 feet extension cords, you'll need a: 16 Gauge for 1-10 Amps. 14 Gauge for 11-13 Amps. 12 Gauge for 14-15 Amps.
As a rule of thumb, fuses are rated according to the power rating of the appliance. If you have to replace a fuse, it's essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating.
A full-size fridge and freezer combination uses 3 to 6 amps on average, but some refrigerators go as high as 15 amps. The amps depend on the fridge's model, make, year, and size. Most modern standard-size refrigerators should be on a 20-amp 120-volt dedicated circuit.
No – you should never run two extension cords together. Connecting two or more extension leads together (sometimes known as 'daisy-chaining) is unsafe for several reasons. Only use one extension lead per socket and never plug an extension lead into another extension lead.
An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.
13 amp sockets are the most common type used in the UK, designed to accept a standard plug used for many types of equipment, appliances and white goods. 13a sockets are offered in an extensive range in various colours, sizes and finishes to suit all needs and décor.
13A Fuse – washing machine, dishwasher, microwave, kettle, toaster, iron.
Do not plug too many things into one outlet, extension cord, power strip, multi-outlet device or outlets on the same circuit. Look for loose connections or damaged or corroded wires, which can also cause an overload.
On average, a washing machine uses 400 to 1,400 watts (W) of electricity, depending on the model. Most washing machines use between 5 and 15 amps and connect to a 120-volt outlet.
Don't plug the cords together
Some people string two extension cords together to get a lengthier one, but this is not a good idea. Extending the cords this way can lead to overheating and overloading, creating a risk for fire. Instead, get one extension cord with the right length.
Q: How many watts can a 13 amp socket take? A: Plugging in 4 items such as a TV, DVD player, Sky Box and games console to an extension , would amount to just over 750 watts = 3 Amps. It is important to never overload a plug socket, which is 3000 watts = 13 Amps. Some appliances use more than others.
Higher-powered appliances draw more amps, so you can plug less of them in before you reach that 13A max limit. For example, a standard lightbulb might draw 0.5A, whereas a microwave will be around 6.5A. A fridge or freezer might be 10A and should never be plugged into an extension lead.
Typically, refrigerators require significant power, especially on startup, and running two from a single outlet can exceed the capacity of standard home wiring, leading to circuit breaker trips or electrical hazards.
The amperage of a standard ceiling fan running on a 120V voltage varies between 0.2 and 6 amps (low to high setting).
Any faulty connections or wiring could cause power surges that lead to a blown fuse or trip a circuit. The problem might not be the connected appliance or the circuit breakers but the faulty or outdated power outlet.
A: Yes. Just use the appropriate size fuse for each circuit depending on what you have hooked up.
The definition of a D-type fuse is a miniature circuit breaker that trips when the current exceeds the rated level by between ten and 20 times. Therefore, a 16 amp Type D breaker will trip if the current reaches between 160 and 320 amps.
