Safety Tips for Using Smart Plugs on Winter Devices


When things get cold, we move inwards space heater, Heated blanket And the layers will appear. Using these heated items puts a little strain on your home’s electrical system. If you don’t pay attention, it can become a big problem. Protect your home from overload and use the tips we’ve gathered here to safely plug comfortable items into your smart plug.

Many people are turning to smart plugs as a way to improve energy efficiency through timers and other smart features. Ours CNET Research The Energy Bill shows that 70% of US adults are doing something to improve energy efficiency at home. My years of testing Portable power station others Energy Monitoring DevicesI have learned that anything that heats or cools requires serious force. This may be what you might want to know about the capabilities of a smart plug when connecting a heater and a blanket to prevent the cold in winter.

From the Fridge story to the iPhone, our experts are here to help make the world a little more complicated.

Smart plugs are great for many things,but The best smart plug There are restrictions. In the US, our homes operate primarily at 120 volts, with some appliances requiring 240 volts. However, the breaker box is another part of the puzzle about the electrical system in our home.

Usually this is hidden in a basement closet or utility room with a gray door. Inside there is a circuit that helps to divide the electrical usage of your home into smaller pieces to avoid overloading the system. These circuits have breakers with an ampere evaluation. If that limit is exceeded, the breaker will move to the plugged-in device to prevent potential fires and tighten the power.

Electrical monitoring devices allow you to check your home system if there are potential issues as an additional layer of prevention. Products like Ting Sensorprovided Partnerships with some insurance companiescheck for electrical hazards of more than 3,000 times per second.

Certified Electrician Derek Rhoades of Tradecraft Electric “Typical containers often referred to as “outlets,” which provide insight into our home circuits, are most commonly rated at 15 and 20 amps. An amplifier, or “amperg,” generates heat when it flows through a circuit. The receptacle must be able to handle the amount of amplifiers flowing through them. ”

The outlets mentioned by Rhoades are hard on the walls of your home. In general, smart plugs reflect the same ampere rating. Most smart plugs are rated at 15 amps, while some are only 10 amps.

Aside from the AMP limitations, the smart plug is also relatively low operating temperatures. As Rhoades points out, “Heating loads such as space heaters can be the most damaging to devices and circuits. They not only produce heat as intended use, but also to create the circuits that operate. It also produces it as a by-product of the large amount of amplifiers flowing.”

Looking at the chart above, you can see that the ratings for smart plugs, hardwired outlets and outdoor plugs are all very similar. However, there are some outliers in it Aeotech Heavy Duty Smart Switch and Leviton GFCI Outlet. These two offer a higher ampere rating, and for Aeotech products, they can operate at 220 volts. But it’s not a plug. Rather, the appliance must be directly attached to the device.

Just as you need to know what you need to know Connect to extension cord and power stripThe same can be said for smart plugs. Most space heaters including our space heaters Best Space Heater Listthe maximum wattage rating is 1,500. It is important to note how much power the appliance draws, the circuit, the breaker, you are connecting it.

For example, if a 1,000 watt microwave is connected to the circuit with a 20 amp breaker and a space heater is connected, there is a risk of overloading that circuit if both appliances are running simultaneously.

Looking back at the previous charts, all these 15 amp smart plugs match well with the 15 and 20 amp breakers that your home uses. However, smart plugs are not as durable as hardwired outlets on the walls of your home. “A 15-amp device can handle 1,800 watts, but devices with that much wattage should only run at that level, at most three hours,” says Rhoades.

“If the load you plan to connect to a 15-amp device exceeds 1,500 and is run over a duration, you should stick to a maximum of about 80% of that total load, which will be 1,440 watts. Masu.”

Space heaters have advantages For safe use, certain steps must be taken. Most smart plugs can handle space heaters. If you choose a heater and plug it in, the power needs of the heater, generally at a height of 1,500 watts, you are sure to need it, and the outlet or plug is highly rated enough to safely handle the electric draw of the heater. It’s been done.

If you use a smart plug, try getting one with a rating of over 15 amps. But they are relatively rare. Another way to reduce the risk of problems is to run the heater at a lower setting. However, using two space heaters for the same outlet and even the lower power settings will also double your power needs, resulting in an overload of the circuit.
