lcd extension cord
Too much plugged into an outlet?
I currently have a lot plugged into my outlets, and I was wondering if it is unsafe, or there is a chance it will blow. I am using two outlets with three surge protectors and a extension cord. In total, I have: Three desktops, two LCD monitors, a laptop, a 24 port switch, a 5 port switch, three wireless routers, speakers, a 500w power supply to power some molex fans, and a printer. I have not had a problem so far, but I am worried that I might soon. The only thing I can really remove is the 500w power supply. These are the only things I have plugged into to ANY outlet in my room, except for a cell phone, and a cable modem. I do not have any testing equipment, and I do not want to buy any. I might be able to re-organize some of the cables into other outlets…am I OK?
I am in the United States with standard power and what not
Most likely your socket is protected by a 15a breaker. At 110v, with a probable power factor around 50%, you DC wattage would have to exceed 800 watts before tripping the breaker. If it did, there’d be no noise, no destruction, just a click and power stops. Your socket would not overheat, no fire would erupt, since everything is rated to handle up to that 15 amps safely, and then the breaker trips, keeping anything from running higher. Since that hasn’t happened, and since electricity has no mind or brain, it’s not going to change its mind and suddenly increase the wattage.
Your desktop computers probably draw 100 – 150 watts each, including the monitors, the laptop probably draws 80 or so, and all the rest (switches, routers, speakers, etc) are statistically insignificant. The 500w power supply for your fans can probably supply up to 500w but is probably really only supplying a tiny fraction at this time.
Your surge protectors (a lousy name, they’re really power strips with minimal, nearly useless surge protection) usually will trip at 10a, long before your house breaker will trip. Since most homes use a single breaker to supply an entire room, and sometimes even two rooms, moving your cables to other outlets is pointless.
Since you haven’t had any problem, then you’re not going to. Unless something changes, like you adding a camera spotlight that draws another couple hundred watts and, again, like I said, the worst that will happen is that your house breaker will just click and shut off. Unplug the super light, and switch the breaker back on, and everything is good.
Where fires break out is when somebody replaces a 15a breaker with a 20a or 30a breaker and the house wiring overheats because it’s still only rated for 15 amps. Or they use several multi tap adapters (called triple taps) that start to become loose due to weight, and don’t have a good connection. Poor connections translate to heat, and combustibles like cloth or paper coming in contact can be heated up enough to burn.
