When we think of the past, one of the first thoughts that runs through our mind is how people lived without electricity. Nowadays, we can’t even imagine a day without it because all of our appliances and devices run on electricity.
The truth is, however, that most homes don’t have enough power outlets to keep everything running and charged, so most of us rely on power strips without being aware that appliances that consume a lot of energy become dangerous fire hazards when we plug them into a power strip.
Although power strips are the thing to go to when it comes to charging your phone or power an entertainment setup, there are certain devices that should never be plugged into a power strip.
Air conditioners, space heaters, toasters, and other appliances that use high wattage can easily cause power strips to overheat, which can easily lead to a fire hazard.
Even before plugging anything into a power strip consider the ammount of power they support. This is usually listed on the product itself.
High-capacity appliances need to draw a lot of power through an electrical circuit to work. Keep in mind that an appliance does not need to be large in size to draw large amounts of power.
Below is the list of appliances that should never be plugged into a power strip.
1. The oven: Even though the oven is not used continually, it is a power-hungry appliance that should not be plugged into a power strip. In fact, it should be plugged into its own wall outlet on its own circuit.
2. Refrigerator: Refrigerators require a lot of power and frequently cycle on and off which can easily overload a power strip and cause damage. Much like the oven, refrigerators require a wall outlet dedicated solely to powering the appliance.
3. Washing Machine: When turned on, washing machines pull a lot of power. This is the main reason why these appliances shouldn’t share a receptacle with any other appliance or device.
Most washing machines use a max of up to 1400 watts, putting it dangerously close to the max load of most power strips. On top of that while working, washing machines are usually left unattended and work longer hours, at least an hour, which is long enough for a power strip to overheat.
4. Heating: Portable heaters should never be plugged into a power strip because most of them use 1,500 watts of energy on their high setting and they usually run for extended periods of time.
5. Microwave: Since they consume a lot of energy when used, most microwave ovens are plugged into their own receptacle and that is always a good practice.
6. Coffee Maker: Those who own a coffee maker are not fully aware of the power these appliances use, and this is why they should never be plugged into any sort of power strip or extension cord.
7. Toaster: You may think that browning up slices of bread or bagels doesn’t require a lot of energy, but the truth is that toasters use a lot of energy when in use and they should be plugged directly into the receptacle rather than a power strip.
8. Another Power Strip: Power strips are not meant to be used in conjunction with another power strip, although many people do exactly that. This, however, violates most safety codes because it can easily lead to overloading the electrical system.
9. Electronics (Computer, TV, Router): These types of electronic devices don’t necessarily use a lot of power on their own, but they are sensitive to surges and you can find yourself with a burnt out computer or TV very quickly if you plug them into a power strip.
If you want to protect these sensitive devices from power surges, opt for a power strip that functions as a surge protector.
IF YOU EVER SEE BLACK CABLES STRETCHING ACROSS THE ROAD, THIS IS WHAT YOU SHOULD DO
Unveiling the black road cables: Silent traffic observers capturing data for smarter road networks. Data-Driven Traffic Insights
As you navigate the highways and byways of your daily commute, you may have encountered an intriguing sight: black cables stretched across the road, almost like stealthy sentinels of the pavement. But what exactly are these enigmatic tubes, and what role do they play in our transportation infrastructure? The answer lies in the realm of traffic management and data collection.
These unassuming black cables are, in fact, portable traffic counters strategically placed by transportation authorities for research purposes. Primarily used by local agencies, these tubes hold vital insights into road usage and traffic patterns. With more than 12,000 of these traffic counters scattered across the state, they provide invaluable data that fuels the planning and development of our road networks.
Decoding the Mechanism Behind the Black Cables
The technology driving these unobtrusive rubber cords is elegantly simple yet remarkably effective.2 Each time a vehicle’s tires contact the tube, a burst of air is triggered, setting off an electrical signal recorded by a counter device. This ingenious pneumatic mechanism can track the volume of vehicles passing over a road within a given timeframe. Transportation agencies can gain insights into peak traffic congestion periods by analyzing the intervals between these air bursts. When deployed in pairs, these tubes provide even richer data, enabling the determination of vehicle class, speed, and direction.
Such information is far from trivial—it forms the bedrock for informed decisions on road signage, speed limits, and allocation of transportation budgets. Based on these insights, municipalities can fine-tune their traffic management strategies, ensuring that road systems remain efficient and safe for all road users.
Road Tubes: Beyond Just Counting
While the primary function of these pneumatic road tubes is traffic counting, their utility extends far beyond mere enumeration.3 These inconspicuous instruments serve as multi-dimensional data collectors, playing a pivotal role in enhancing our road infrastructure and ensuring smooth traffic flow.
The U.S. Department of Transportation sheds light on the operational intricacies of these tubes. When a vehicle’s tires traverse the rubber tube, a burst of air pressure is generated, closing an air switch that sends an electrical signal to a counter device. These tubes can be set up either as temporary or permanent installations, each serving distinct purposes. Temporary configurations, often lasting only a day, offer quick glimpses into traffic dynamics, while permanent setups provide continuous, in-depth monitoring.
Transportation agencies strategically position these black cables in areas with minimal interference, targeting straight stretches of road for optimal data collection. Through single-tube setups, agencies can gauge vehicle counts and time gaps between vehicles. When utilizing paired tubes, the system delves into the intricacies of traffic, capturing axle count, direction, and speed.
These unassuming tubes also step in when urban road management faces challenges. If residents raise concerns about speeding or shortcutting, these tubes are deployed to investigate and validate claims. The data they generate contributes to the formulation of transportation budgets and the implementation of effective solutions.
In conclusion, the next time you encounter those mysterious black cables stretching across the road, you can appreciate the intricate web of data they weave behind the scenes. These unassuming instruments serve as silent observers, capturing the heartbeat of our roads and guiding the decisions that shape our transportation landscape. As you pass over these tubes, remember that they are more than meets the eye— they are the pulse of our evolving road networks.
