How many devices can you plug into one outlet? A standard rule of thumb is that you can plug in two to three devices at a time into a single socket. To begin with, there are a few things you need to think about before adopting this rule. The most important factor is the amperage of the circuit breaker.
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.
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.
Ideally, you should spread as many outlets around your home as possible and assign them to a single circuit. Just keep in mind the maximum load for a single circuit. A good rule of thumb is to assume that there will be a maximum power draw of 1.5 amps for each outlet, allowing 10 outlets for a single 20-amp circuit.
Here are the recommendations by the ESC (National Electrical Safety Council). Do Not Overload Sockets. Remember the 13 amp rule. A maximum of a total of 13 AMPS into 1 socket.

Its not so much a matter of overloading sockets but instead the total wattage of the devices going in to the sockets. A good rule of thumb is to keep the total wattage under 3000w, anymore and it could become a potential fire hazard.
If your circuit can handle up to 2,000 watts within the 80 percent amperage safety limit, you should be fine -- the brightness of so many bulbs would probably burn your eyes out before it would your electrical outlet.
Plugging two refrigerators into the same outlet is not recommended due to potential safety risks and the likelihood of overloading the electrical circuit.
Too many appliances on a single socket implies too much load is shared across several nodes. The current will rise much higher as a result of this. If the socket does not have a fuse, the wiring of the socket may burn as a result.
Overloaded Electric Outlets: The Warning Signs
Wall plates that are warm to the touch. Discoloration on socket and light switch plates. Crackling, sizzling or buzzing sounds.
Just two typical modern 18cf fridges/freezers that draw 6 to 8 amps each aren't going to trip a circuit breaker. But this circuit may or may not feed other outlets, so you need to identify if other outlets and what other devices might otherwise cause an overload.
Too many appliances being plugged into the same circuit will exceed the load the circuit was created for and begin to trip the circuit breaker causing the whole thing to close. The same issue arises when homeowners stack extension cords and other plugs that allow you to fit more than two appliances to an outlet.
A single outlet usually limits you to plugging in two to three devices which may not always be convenient. Power strips, also known as surge protectors, contain multiple outlets so you can power several more devices all from the same source.
It is not recommended to connect a refrigerator to a multi-outlet. If it is unavoidable, please use one with a power rating of 15 ampere or higher.
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.
Refrigerators can be power-hungry appliances, and sharing an outlet with another device can lead to overloading the circuit. Additionally, the start-up surge of power that refrigerators experience when their compressors kick in could affect the performance of other devices connected to the same outlet.
Outlets can be loaded to 12 devices per one circuit. (the recommended load is 8-10 outlets to allow for future expansion). These outlets must be protected by an AFCI breaker. Overhead lighting can be loaded to 12 fixtures per circuit.
You should never use a microwave and refrigerator on the same circuit The NEC requires that permanent microwave devices have a dedicated circuit. The same could be said about refrigerators. However, you should be clear on which type of refrigerator is in question.
Yes, an outlet can cause a fire if nothing is plugged in. However, it is highly unlikely that your outlet will catch fire with nothing plugged in as long as: You have not just overloaded the outlet and just unplugged something from it. The wiring is not faulty.
Can you connect two outlets to one outlet? Yes, you can connect two extra outlets (or more) to one outlet if the total load on the circuit allows for it. If you have a 15-amp circuit, electrical code allows up to eight outlets or light switches.
The standard outlet is 120V, so you can safely plug 1,440 watts into a 15 amp circuit without going over the 80% threshold. Simply add the watt requirements of the appliances you are plugging in and make sure they don't exceed this amount.
You should only plug in 4 appliances if their combined power draw is no more than the capabilities of the adaptor.
The problem is, plugging multiple devices into one outlet using a splitter adapter you bought at a hardware store might overload the outlet. You might trip a circuit breaker, damage your electrical equipment, or even cause a fire.
