If you’ve ever grown frustrated by a lack of outlets in your Charlotte, NC, home, you may have wondered what you could do to remedy that. 电工可能会用两种不同的方法在家里安装更多的插座. 如果你的主电器箱里有多余的断路器, they could run a whole new circuit to add outlets where you want them. 如果你没有空间或运行一个新的电路将是多余的,你需要什么, they might instead add outlets to an existing circuit. But how many outlets can you have on a single circuit? Here’s some information to help you understand your options.
110V or 220V?
In American homes, there are two voltages that you will find. 高压电路运行主要的、高需求的电器,如烤箱、干衣机和炉子. 这些电路通常只运行一个项目本身,不能支持在没有适配器的情况下运行在110伏的项目. 美国家庭中的绝大多数电器都是用110伏电压运行的. 因此,110V电路将是本博客中讨论的电路类型.
All Circuits Aren’t Equal
要确定给定电路可以支持多少个插座,首先需要知道的是它的断路器可以处理多少安培. 这也会告诉你电路的接线可以安全处理多少电流. 在普通家庭中,你会发现支持大多数插座的电路有两种不同的安培数.
支持插座的电路的第一个也是最常见的安培是15安培. 这就是你通常会在家里生活空间的电源插座上找到的电路. 这个容量足以支持一系列普通的电子设备,比如灯, televisions, and other low-wattage devices.
第二个常见的安培,你会发现在普通家庭的插座电路是20安培. 这通常是你在厨房电源插座的电路上找到的安培数, your home’s bathrooms, and other areas that might have higher-wattage devices plugged in. The extra power makes it possible, for example, 给冰箱插上电,剩下的电量足够给烤面包机供电, a microwave, or other power-hungry small devices.
你可能还会发现有两个房间的插座和照明用的是20安培的电路. Or, 你可能会发现一个20安培的电路处理三个房间的所有插座, with a separate 15-amp circuit powering the three rooms’ lights.
Maximum Number of Outlets by Amperage
你可能会惊讶地发现,美国国家电气法规并没有规定一个电路可以连接多少个插座, regardless of its size. Instead, 它只是规定你只能有相当于电路容量80%的插座. The reason for that is simple. 你还得考虑你打算把什么东西插到插座上. 这个想法是填充你的电路少于理论最大数量的插座,它可以支持, so you won’t trip your breakers all the time.
Since it’s impossible to foresee every possible use of a circuit, 电工通常假定每个插座最多为1个插座供电.5 amps at any given time. 以此为指导,你可以有多达8个插座连接到一个15安培的电路. 当然,这是假设,电路上除了插座没有其他连接. For a 20-amp circuit, that number rises to 10 outlets. Electricians will also add hardwired items on the circuit, like light fixtures, to your total of outlets when doing this calculation.
值得注意的是,这些是基于平均预期使用量的最大出口计数. In reality, you can add as many outlets to a circuit as you wish, 只要你不同时使用超过8个,或者你只在电路的插座上同时使用低瓦数的设备.
How to Estimate Your Power Needs
如果你家里的电路已经有了最大欧博体育allbet数量的插座, it may be possible to add more, anyway. 但是,这样做需要您估计所讨论的插座的电力需求.
To do that, 你需要把你计划插入电路插座的所有设备的功率加起来. You can find this information on each device, either on an affixed label or printed on its power plug. Once you have that information, you can plug it into a formula to convert your total to a value in amps.
To do it, just divide your total wattage by 120. Using that formula, 你需要确保你使用的设备不会绘制超过1,440 watts at once on a 15-amp circuit. 在一个20安培的电路上,你可以同时操作总计达1920瓦的设备. 这两个数字都将使您保持在每个电路欧博体育allbet的80%容量内.
Using that information, 你可以决定你家里的一些电路可以支持一些额外的插座. However, if you added those outlets, you would have to keep in mind the circuit’s limitations going forward. And if your power needs change in the future, you might be stuck with a circuit breaker that trips constantly, rendering those extra outlets useless.
Adding New Circuits Is Preferable
In most cases, 你不太可能在家里发现电路的插座比它们能安全处理的要少得多. At most, 你可以在家里的电路中增加一两个插座,而不会给自己带来问题. In most cases, 这是一个更明智的长期选择,在你的主电器面板上添加新的电路来支持你想要的新插座.
To do this, 我们的一位电工将评估您现有的主电气面板,看看它是否有容量和空间容纳您需要的额外电路. In some cases, 你的家可能需要一个新的电板,甚至是电网供应商的服务升级. If so, our electricians can handle the whole process for you. And afterward, 你最终会拥有一个更经得起未来考验的家,它的电气系统可以毫无困难地满足你现在和未来的电力需求.
