在我的厨房里,我想用一种保护的预防GFCI的容器更换常规的120V插座。这些说明描述了与常规2线+接地饲料有关,随着其他容器,没有雏菊链接,但不是如何用3线+接地进料进行。请描述如何连接新的插座。

这是我最好的6岁艺术性的非GFCI插座如何接线的图: 当前插座连接图

我认为这是这种方式,使厨房中的每个插座都有两个由不同断路器提供的插座。在服务面板,电路由连接的15A断路器控制。我假设白色和黑色是单独的15a线,红色是一个常见的中性(?)。

以下是用于连接2线场景的说明。

英文原文

In my kitchen, I want to replace a regular 120V receptacle with a GFCI-protected receptacle. The instructions describe what to do with a regular 2-wire + ground feed, with and without daisy chaining to other receptacles, but not how to do it with a 3-wire + ground feed. Please describe how I should connect the new receptacle.

Here's a diagram of how the non-GFCI receptacle is currently wired, in my best 6-year-old artistry: diagram of current receptacle connections

I think it's connected this way so that each receptacle in the kitchen has their two sockets supplied by different breakers. At the service panel the circuit is controlled by a joined pair of 15A breakers. I assume the white and black are separate 15A lines and the red is a common neutral (?).

Here are the instructions for connecting in a 2-wire scenario.

How do I connect this? Or should I consult an electrician?

最佳答案
 

第一个问题是您可能使用错误的电缆和断路器。 NEC呼叫厨房中的2个20次小电器电路,实现这一点,您需要切换到20amp断路器和#12线。

下一个问题。如果要挂钩GFCI插座,您必须拉出新电线。 GFCI插座无法使用共享中性,您将最终与共享中立的滋扰绊倒。 GFCI容器通过监测热和中性之间的平衡,因此如果中立分享,GFCI将无法正常工作。

将厨房正确连接,您必须将2个新的12/2电缆从断路器拉到厨房(所有#14线在该电路上必须更换)。然后安装2个20扬声器,供应厨房。您将在每个电路上安装GFCI作为第一插座,这将保护所有下游插座。

您可以在2个GFCI插座之间共享中性。抓住是你必须掌握中性到容器,而不是使用第一个GFCI的负载侧的中性来喂食第二。

所以你应该能够做到这样的事情...

然后,您将能够使用每个插座的负载侧来馈送其他设备。

The first problem is that you may be using the wrong cable and breakers. NEC calls for 2 20Amp small appliance circuits in the kitchen, to accomplish this you'll need to switch to 20Amp breakers and #12 wire.

The next problem. You'll have to pull new wire anyway, if you want to hook up GFCI receptacles. GFCI receptacles will not work properly with a shared neutral, you'll end up with nuisance tripping with a shared neutral. GFCI receptacles work by monitoring the balance between hot and neutral, so if the neutral is shared the GFCI will not work properly.

To wire up the kitchen properly, you'll have to pull 2 new 12/2 cables from the breaker to the kitchen (all #14 wire on that circuit will have to be replaced). Then install 2 20Amp breakers, to supply the kitchen. You'll install the GFCI's as the first receptacle on each circuit, which will protect all downstream receptacles.

You can share a neutral between 2 GFCI receptacles. The catch is you'll have to pigtail the neutral to the receptacles, not use the neutral from the load side of the first GFCI to feed the second.

So you should be able to do something like this...

But not like this...

enter image description here

You'll then be able to use the load side of each receptacle to feed other devices, like this.

Gregmac所说的大部分是正确的,但我必须纠正几个小物品。它是完全可以接受的,经常使用三线电路(黑色/红色热,白色中性和amp;裸地),如您必须"备用" 厨房容器,从而为您提供两个电路。拆分回收的顶部和底部并不是一个代码要求,但这很好,但它使GFI功能复杂化。分裂顶部和底部需要两个GFI的上游,一个喂养每个腿。更常见的是面板中的两个单极GFI断路器。

如说,你的情况是不同的。我打赌你会发现黑色喂食其他每一个召唤,同样是红色与替代的再现相同的东西。确认一旦确认,只需在每个字符串(颜色)的第一个供电的注定上安装GFI。事实上,这是最常见的方式有线和符合NEC。
 

Most of what Gregmac has said is correct, however I have to correct a couple of small items. It is totally acceptable and often done to use a three wire circuit (black/red hot, white neutral & bare ground) like you have to "alternate" kitchen receptacles, thus giving you two circuits. It is not a code requirement to split the top and bottom of the recpts, however it is fine to do that, but it complicates the GFI functions. Splitting the top and bottom would require two GFI's upstream, one feeding each of the legs. More common would be two single pole GFI breakers in the panel.

With that said, your situation is different. I bet you will find that the the black feeds every other recpt, and likewise the red does the same thing with alternate recpts. Once you confirm that, simply install a GFI on the first powered recpt of each string (color). As a matter of fact, this is the most common way kitchens are wired and meets NEC.

我怀疑一些作家令人困惑使用新电流操作GFCIS的GFCIS。现代型含有一点环形变压器,即现场和中性穿过。通常,GO和返回电流是相等的,因此变压器没有。如果电流不等于,变压器会产生操作跳闸继电器的电压并切断电源。

旧类型的GFCI使用地球杆。房屋地线连接到GFCI的跳闸线圈的一端。跳闸线圈的另一端连接到地球杆。如果房屋中的任何内容泄漏电流,GFCI将关闭电源。这种类型的GFCI的问题是电气风暴可以吹跳闸线圈。这让所有内容留在屋内未接地,没有GFCI。

我被要求"看" 的一个令人愉快的财产是让每个人的电击。楼层是混凝土,简易别墅的电压为GFCI,带有吹式线圈。我怀疑浸没式加热器元件也腐蚀,现在将电流泵入热水系统。水龙头,灯开关,厨房范围以及应该接地的任何金属都是活着的!该物业由一个独立寡妇拥有,没有钱可以正常完成工作。从杆变压器供应电源,将11,000伏特滴到240,并且随着这些中性总是在杆处接地。在检查所有法律填写后,决定使用PME(保护多次接地),重型线连杆连接在所在的熔断板上的中性和保护导体(AKA"地球" )之间连接到建筑物的熔丝板上。结果没有更多的电击!我大约三十年前这样做了"bodge" ,它仍然很好。可悲的是,寡妇很久以前就过了。她死于老年而不是触电。

imho那些电压运营的GFCIS从20世纪50年代和20世纪60年代应该被禁止。他们可能是,但人们仍然使用它们。

一个由朋友固定的接线的老房子有两根电线(活和中性但没有地球)系统,其中电线被放入木制管道中的凹槽中。鼠标造成短暂并吹过保险丝。如果电牌已经看到古色古香的接线,他们将需要一个完整的重新加线,这将花费成千上万!小心!

 

I suspect that some writers are confusing the old Voltage Operated GFCIs with the new Current Operated GFCIs. The modern type contain a little toroidal transformer that the live and neutral are threaded through. Normally the go and return currents are equal so the transformer does nothing. If the currents are not equal the transformer produces voltage which operates the trip relay and cuts off the power.

The old type of GFCI uses an earth rod. The house earth wires connect to one end of the trip-coil of the GFCI. The other end of the trip coil connects to the earth rod. If anything in the house leaks current the GFCI will turn off the power. The problem with this type of GFCI is that electrical storms can blow the trip coil. This leaves everything in the house un-earthed and with no GFCI.

One delightful property that I was asked to "look at" was giving everyone electric shocks. The floors were concrete and the bungalow had a voltage operated GFCI with a blown coil. I suspected that the immersion heater element had also corroded and was now pumping current into the hot water system. Water taps, light switches, the kitchen range and anything metal that was supposed to be earthed were all live! The property was owned by a penniless widow and there was no money to do the job properly. Power was supplied from a pole-transformer dropping the 11,000 volts to 240 and with these the neutral is always earthed at the pole. After checking all the legal stuff it was decided to use PME (Protective Multiple Earthing) A heavy duty wire link was connected between the Neutral and the Protective Conductor (AKA "Earth") on the fuse-board where the power entered the building. Result no more electric shocks! I did that "bodge" about thirty years ago and its still working fine. Sadly the widow passed away long ago. She died of old age not electrocution.

IMHO those voltage operated GFCIs that date from the 1950s and 1960s ought to be banned. They probably are but people still use them.

One old house that had its wiring fixed by a friend had a two wire (live and neutral but no earth) system where the wires were let into grooves in wooden conduits. A mouse had caused a short and blown a fuse. If the Electricity Board had seen the antique wiring they would have demanded a full re-wire which would have cost thousands! Take care!

取决于您想要保护的内容。

如果您只想保护该插座,那么它很容易。辫子黑色和白色电线并将它们连接到GFCI的饲料侧。留下GFCI断开连接的负载侧。

如果您想要保护下游插座,它会变得棘手。通过GFCI流出的电流必须通过相同的GFCI返回。否则会绊倒。因此,要使用GFCI插座保护两个热点,您需要两个这样的网点,并且您需要将中性量保持在GFCIS分离的下游,这可能需要一些重新兴奋。

替代方案可以是在面板上使用双极GFCI断路器。

另一个替代方案只是为了在每个出口处安装单独的GFCI。

 

It depends what you want to protect.

If you just want to protect that outlet then it's easy. Pigtail the Black and white wires and connect them to the feed side of the GFCI. Leave the load side of the GFCI disconnected.

Where it gets tricky is if you want to also protect downstream outlets. Current that flows out through a GFCI must return through the same GFCI. Otherwise it will trip. So to protect both hots using GFCI outlets you would need two such outlets and you would need to keep the neutrals downstream of the GFCIs seperate which would likely require some rewiring.

An alternative may be to use a double pole GFCI breaker at the panel.

Another alternative is just to install a seperate GFCI at each outlet.

该"共享中性" 电路实际上是一个称为多线分支电路或MWBC的电路。 你必须遵守他们的规则

规则:您必须 pigtail 中立。在您所示的情况下,您不能将2个中性螺钉与Daisychain一起使用。

共享中性电路必须使用相同的2极断路器

(好的。还有一个涉及手柄关系的例外。但忽略这一点,因为这个segways进入了一个非常有用的东西!)

共享中性的两个"热点" 必须落在2极断路器上。该2极断路器确保了"公共维护关闭(MWBC规则" 和在120V极相对的相对(A 非常绝对 MWBC规则)上)。

保护共享中性与2极GFCI断路器

在发生时,它们使2极GFCI +断路器接受2个Hots 和中性。这就是你的电缆。

适用于2极GFCI断路器,将其中性猪尾连接,并带来所有3个电线:热量和中性到GFCI断路器。 ,你已经完成

这将完全保护MWBC /共享中性电路的任何任何法律配置。您不必担心中性如何从负载中共享和防火板。 它只是有效

"哦,但是2极gfci断路器昂贵" - 四个GFCI +插座也是如此,因为您在编辑中绘制时显示。

如果必须使用许多GFCIS - 只是不使用LOAD

如果您绝对坚持使用GFCI +插座设备,嗯....好的。您可以在您的最后一个绘图中进行(在编辑中)。

这使其成为非常简单规则:不要从 LOAD 终端删除警告磁带 。就那么简单。当然,你会坐在那里诱惑,对吗? 2条电线在手中和2个螺钉,你不能使用--- nuh uh 不要触摸该磁带!你必须用另一种方式弄明白。 双手关闭!

这将导致您到一个名为盗版的概念,我提醒您,您需要根据MWBC规则与中性人士进行。所以,现在你也用热门做。掌握到 LINE 热和中性和 voila 上的每一个连接。您可以在您选择适合GFCI +插座的地方提供GFCI保护。它没有爆炸你的大脑。

 

This "shared neutral" circuit is actually one circuit called a Multi-Wire Branch Circuit or MWBC. You must comply with their rules.

Rule: You must pigtail neutrals. You can't use the 2 neutral screws to daisychain through the receptacle as you illustrated.

Shared-neutral circuits must use the same 2-pole breaker

(Okay. There's an exception involving handle-ties. But ignore that, because this segways into a very helpful thing!)

The two "hots" that share the neutral must be landed on a 2-pole breaker. This 2-pole breaker assures common maintenance shutoff (an MWBC rule) and that the hots are on opposite 120V poles (a very absolute MWBC rule).

Protect a shared-neutral with a 2-pole GFCI breaker

As it happens, they make 2-pole GFCI+breakers, which accept 2 hots and a neutral. And that's what your cable is.

You fit the 2-pole GFCI breaker, attach its neutral pigtail, and bring all 3 wires: both hots and neutral to the GFCI breaker. And you're done.

This will fully protect any legal configuration of MWBC/shared neutral circuit. You don't have to worry about how neutral is shared and firewalling line from load. It just works.

"Oh, but 2-pole GFCI breakers are expensive" -- so are four GFCI+receptacles, as you show in the drawing in your edit.

If you must use many GFCIs - just don't use LOAD

If you absolutely insist on using GFCI+receptacle devices, well.... okay. You can do as in your last drawing (in your edit).

This makes it a very simple rule: Don't remove the warning tape from the LOAD terminals. Simple as that. Of course, you'll be sitting there tempted, right? 2 wires in your hand and 2 screws you can't use--- nuh uh don't touch that tape! You have to figure it out another way. Hands off!

This will lead you to a concept called pigtailing, which I remind you, you need to do with the neutrals anyway because of MWBC rules. So, now you're doing it with the hots too. Pigtail every connection onto the LINE hot and neutral, and voila. You have GFCI protection everywhere you choose to fit a GFCI+receptacle. And it didn't explode your brain.

不要复杂这个。这是非常简单的问题。只需单独留下红色线。这里没有人知道它用于它的用途,但它并不重要。每个电工/房主都有一些不同的东西。它可能是正确的还是错的,但如果一切都有工作,不要担心它。

不使用红色线,您可以使用您提供的图表。唯一要弄清楚的是电线是热饲料。最简单的方法来看出来是关闭断路器并断开一组黑色和线线。然后将单独的线螺母放在每个上并重新打开断路器。如果出口仍然有效,那么连接的电线很热。如果没有,那么显然你起飞并加盖的电线是。现在您必须决定您是否希望在此系列上的其余插座是由GFI保护并相应地连接负载线。它将是GFI背面的标签,其中负载连接点受到保护。

 

Dont over complicate this. It is very simple problem. Just leave the red wire alone. No one here knows for sure what it is used for but it doesnt matter. Every electrician/homeowners wire things a little different. It could be right or wrong but if everything works dont worry about it.

Without using the red wire you can use the diagram you provided. The only thing to figure out is what wires is the hot feed. The easiest way to find this out is to turn off the breaker and disconnect one set of black and wire wires. Then put a separate wire nut on each and turn the breaker back on. if the outlet still works then the wires connected are hot. If not then obviously the wires you took off and capped are. Now you have to decide if you want the rest of the outlets on this series to be protected by the GFI and connect your load wires up accordingly. It will be label on the back of the gfi which load connection point is protected.

Bmitch的帖子是部分正确且危险的错误。 3电线(2)120V电路共用一个中性的电路应连接到带2极断路器的线路,并且必须在相反的相位(偶数/奇数断路器位置,穿过阻挡器240V)。共享中性带有不平衡的负载,使得一个电路上的15个放大器,另一个电流为5安培,导致10个放大器中性电流。每个相反相位电路平衡的15个放大器,取消中性电流至零(0)放大器。在2个相同的相位电路上共用中性(偶数/偶数/奇数/奇数电路位置,横跨断路器),因为它导致添加中性电流,其中每个电路上的15个放大器导致中性,危险的过载导体30安培。不应使用相邻的单极断路器,并且不应完成甚至/相反电路位置的跳过面板空间 - 出于安全原因,如果打开共享中性拼接,则在电路上打开一个断路器的安全原因会导致危险状态,通过共用电路激励。两个电路必须关闭。

 

BMitch's post is partly correct and dangerously wrong. 3 wire circuits of (2) 120V circuits sharing one neutral should be connected to lines with a 2-pole breaker, and MUST be on opposite phase (even/odd circuit breaker positions, 240V across breakers). Shared neutral carries unbalanced load such that 15 amps on one circuit, 5 amps on the other, results in 10 amp neutral current. 15 amps on each opposite phase circuit balance, cancelling neutral current to zero (0) amps. Sharing neutral on 2 same phase circuits (even/even - odd/odd circuit positions, 120 V across breakers) should NOT be done as it results in additive neutral current where 15 amps on each circuit result in 30 amps on neutral, dangerously overloading conductor. Adjacent single pole breakers should not be used, and skipping panel spaces for even/opposite circuit positions, should NOT be done - for safety reasons where turning one breaker off to work on a circuit can result in dangerous condition if shared neutral splice is opened, being energized via the shared circuit. Both circuits must be OFF.

白色,黑色,红色线/ GFI插座

白色带有未使用的电源。 黑色红色携带电力(为您的废话供电) 但要小心(如果黑线附着在标有偶数的电气面板上的断路器上,并且红色附加到奇数(难以注意到盖子旁边的盖子上的盖子上)奇数奇数奇数好的= 240繁荣! 所以,如果黑色x和红色y然后继续: 黑色到线孔上的gfi(废话挂钩加载) 红线不挂钩,扭曲在一起传递到下一个位置。下一个位置挂钩红色到GFI上线,也不连接黑色。 只是不要在同一地点陆上黑色和红色,红色gfi =微波黑色gfi =冰箱红色gfi =搅拌机黑色gfi =咖啡壶 白色电线应直接直接到每个GFI而无需绕气。不要从负载或线路上使用白色的gfi但扭曲一束,所以1白点击黑色gfi 1一个白色点击红色gfi 2,背gfi 2,红色gfi 2 ....等等。

常规非GFI规则

您可以共享来自任何带有相同颜色的任何插座的白色线,只要与相同的彩色线,它的兄弟白线被挂钩到已知的偶数或奇数标签(冲压旁边的断路器)奇数至偶数十字架120 + 120 = 240甚至甚至120 + 120 = 0,因为它相同的相位(几乎与阶段2的电源分离的阶段1)差异几乎相同的120似然在120时彼此几乎常见。红色和黑色制作240,红色和红色制作120我错过了什么?

 

white, black, red wires/GFI receptacle

white carries unused power back. Black n Red carry power in (to power your crap) But be careful ( if black wire is attached to a breaker at the electrical panel that is labeled an even number and the Red is attached to an odd number (hard to notice stamped numbering on cover beside breakers) Odd to odd OK Odd to even Not ok = 240 boom! So if Black X and red Y then proceed with: black to Line holes on gfi (crap hooked up to Load) Red wire dont hook up, twist together to pass to next location. Next location hook red to LINE on gfi and dont connect black. just don't land black and red on same location, red gfi = microwave black gfi = fridge red gfi = blender black gfi = coffee maker White wire should go directly to each gfi without detour. don't use white from load or line off gfi but twist a bunch so 1 white hits black gfi 1 one white hits red gfi 2, back gfi 2, red gfi 2 ....etc.

regular non-gfi rules

you can share the white wire coming from any receptacle with the same color as long as the same colored wire and it's brother white wire are hooked up to a known even or odd label (stamped next to breakers) odd to even cross 120+120=240 even to even 120+120=0 since its the same Phase (odds are phase 1 separated from power on phase 2 evens) odds are all virtually the same 120 evens are virtually common with each other at 120. red and black make 240, red and red make 120 did i miss anything?

我正在重新加起浴室,并将在20安培断路器上安装GFCI插座(仅限于仅限浴室)。我也将在同一电路上有一个风扇和虚荣灯,GFCI出口下游(风扇位于桶上方,因此需要GFCI保护)。问题:在GFCI插座的下游,我需要继续在其余的电路中使用12个AWG电缆,或者我可以切换到14 AWG?代码引文随着任何理由而言,为什么允许/不...

15  电源停电后的GFI网点  ( Gfi outlets tripped after power outage ) 
我住在一个经常停电的农村地区(每月几个。持续时间不到一分钟)。当电源恢复时,几个GFI网点总是跳闸。我试图追踪这些旅行的原因,因为其中一个插座为动物的安全为牲畜热水器(在冰冻月期间需要停留)。 跳闸连接到从主面板馈送的子面板的GFI出口。关闭和ON的断路器还可靠地浏览所讨论的GFI插座。我已经复制了这一点,没有任何东...

1  在连接到开关和GFCI的浴室中接线灯具  ( Wiring a light fixture in bathroom attached to a switch and gfci ) 
我在改造过程中更换浴室中的所有组件。我有一个具有灯开关和GFCI的盒子,开关控制梳妆台。当我删除旧夹具时,我忽略了记录一切都被挂钩了。 一切似乎都被正确地挂钩,交换机控制夹具没有问题,但GFCI不会重置它保持跳闸。 任何想法? 开关的盒子和GFCI似乎直截了当,两组3根电线,1个黑色,1个白色和1个地面。为交换机设置...

0  GFCI插座 - 为什么没有绿色LED指示灯?  ( Gfci outlet why no green led indicator ) 
刚刚安装了新的GFCI。当我插入它有电源的设备时,然后按测试按钮和电源丢失,然后按RESET按钮和电源重新打开。除了没有绿色LED指示灯,一切都似乎是工作 - 为什么?? ...

1  多个GFCI插座,冰箱正在绊倒它,它不会插入  ( Multiple gfci receptacles fridge is tripping one it inst plugged into ) 
我最近在我的车库里放了一个冰箱,我发现我发现的出口是在与卫生间在室内的浴室。我相信以前的主人在他是"承包商" 时安装了它,并在房子上做了很多工作。 电路上有3个插座,所有3都有GFCI插座。我会打电话给他们,a,b和c. a位于车库中,B和C在浴室里。冰箱插入A,除非我们让客人留在我们身边,否则没有插入B或C.当冰箱...

2  似乎在同一电路上的网点,但不表现这种方式  ( Outlets that seem to be on same circuit but not behaving that way ) 
我正在尝试在厨房安装一个gfci outlet。我的理解是您可以在电路上安装一个GFCI,这将保护所有其他插座。这假设GFCI插座安装在电路的开头。 (如果我错了,请纠正我)。 在尝试识别电路开始时的插座上,我逐个逐一挂断,并将其中的每一个断开,测试其他人。它们似乎彼此独立运作。断开一个插座对他人没有任何作用。 是什...

1  从GFCI上游的插座具有导致GFCI旅行的问题?  ( Receptacle upstream from gfci with an issue causing gfci to trip ) 
我不确定接下来要做什么,而且我公平地缺乏故障排除家庭电气问题。我的调查开始于厨房柜台容器跳闸的GFCI容器跳闸而未重置。我取代了所有负载容器,以确保接线很好。我替换并双重检查了GFCI插座。仍在绊倒,即使负载甚至没有连接到GFCI插座。 我最终从GFCI看起来上游,发现了GFCI上游的容器已经死了。我断开了插座以测试...

13  为什么GFCI在冰箱电路上跳闸?  ( Why would a gfci trip on refrigerator circuit ) 
我的冰箱正在插上插座上的gfci。搜索关于这个话题似乎表明这是一个合理的共同投诉。但是,除了建议之外,我找不到有关一般原因或潜在解决方案的具体信息,以取代所有内容和最佳希望;这似乎不满意。 这是一个新的冰箱和许可专业人士的所有新电气工作。我相信电气安装正确并接地,并且冰箱没有损坏。我认为这是一个专用电路,从破碎板到冰...
