Outlet which side is hot

You see, the wiring has already been installed by the builders and they left the boxes without receptacles so all I have to do is connect them to the. I don't know why the extra red wire is there. It was done over a year ago.

I want to finish the connections. That's why I have the extra red. Rick often electricians run a 3-wire system into a building area using two hot wires and a shared neutral, to permit providing two circuits in an area while having to pull just one wire to the area. But to sort out how your wires were connected and are being used requires some expertise, visual inspection, and testing using a VOM.

What is the difference between the load and line terminal screws on a 15 or a 20 amp receptacle? How do i wire 4 more recepticles to an existing receptacle in a room? Our photograph left illustrates the line and load markings on the back of a GFCI electrical receptacle.

Looking at the side or back of the molded case of this and other electrical devices such as AFCIs, you will see that one pair of terminals will be marked "line" and the other "load". The Line terminals green arrows in photo at left on an electrical receptacle are for the incoming hot wire - the terminal marked LINE is connected to the incoming power source or the "hot" wire typically black or red in insulation color that connects to the brass colored screw marked "Black" or "Noir at the lower left " in our photo.

And the incoming neutral white wire from the electrical panel connects to the "Line" and "White" or "Blanc" terminal marked at the lower right in our photo. The Load terminals red arrows near the top of our photo at left on an electrical receptacle are for the outgoing wires. These wires feed electrical receptacles that are located "downstream" farther from the electrical panel from the device. The outgoing hot or black wire red arrow, above left in our photo connects to the terminal marked "Load" or "Charge" and "Black" or "Noir".

The outgoing white, neutral wire, connects to the terminal marked "Load" or "Charge" and "White" or "Blanc" in our photograph. The LOAD terminals of that device are connected to hot and neutral wires that subsequently are connected to the next electrical receptacle in the series.

And often we wire two separate electrical circuits to the box, placing one pair of receptacles on one circuit and the other on the second circuit - that approach allows us to plug more devices into the wall at that location with less chance of overloading a single electrical circuit in the building. Watch out : while a conventional receptacle may work with the line and load terminals reversed, a GFCI or AFCI will be unsafe if wired with that mistake, and those devices will not work properly nor test properly in all circumstances.

For example, if you connect the incoming "hot" wire and neutral wire to the "load" terminals on a GFCI, and if you connect wires leading to downstream electrical receptacles to the "line" terminals these are the incorrect connections , then pushing the test button on the GFCI will not activate that device's internal trip mechanism.

If the devices is not wired correctly it is unsafe and does not provide the intended safety protection from ground faults. There are two approaches to physically connecting electrical wires to an electrical receptacle "Outlet" or to an electrical switch "light switch" or "wall switch". Back-wiring means connecting the wire through an opening or into a clamp accessed on the back of the receptalce or switch.

Alternatively a wire may be connected directly to a screw on the receptacle or switch as we show in the photo below. Most literature refers to these as "binding head" screws or "binding head screw connector" because the head of the screw on modern receptacles and switches is designed to grip the electrical wire to hold it securly in place.

Some old switch or receptacle screws were rounded or tapered a bit on their underside or at their outer circumference so that if you were not careful the wire would pop out of place when tightening the screw. We do not recommend using the push-in back-wire connection that relies on a simple spring-clip device inside the receptacle or switch because that connection has both less contact area and less clamping force on the wire.

Below our photo illustrates using the not-recommended push-in back-wire connection that relies only on a spring clip connector.

You can see that this receptacle also offers side-mounnted binding head screws recommended. Watch out : We have seen field reports of receptacle burn-ups that all involved spring-clip push-in type backwire connections. The steps in connecting a wire to a binding head screw are simple but require a bit more labor than connecting an electrical wire in a screw-clamp type connector.

Both of those approaches make good connections, and you'll find that on some receptacles and switches you have only two choices: push-in spring-clip back-wiring, or using the side-mounted binding-head screw. The proper wire size for 15A or 20A circuit and type and number of connectors have already been selected.

And you've already determined which wires go to which terminal. And you already know which wires go where, as we discussed. Watch out : electrical wiring involves fire, shock, death and other safety hazards. In many jurisdictions electrical wiring can be performed only by licensed electricians. We recommend hiring a qualified, licensed electrican for electrical work.

Even where home-owner electrical work is permitted, permits and electrical code and safety inspections are usually required. Check with your local building department. Above I'm showing the wire strip-back gauge area marked on the back of a 15A electrical receptacle. This gauge shows the amount of insulation that should be removed presumably for either of the types of connectors provided on this particular device. Below is a rather shorter wire stripping gauge telling us that for the device where this gauge appears - in this case a screw-clamp type wire connector, somewhat less insulation is to be removed.

For the device shown below we are to remove 9mm of insulation - about 0. Watch out : don't strip off too little insulation or the wire will not make a safe, reliable electrical connection: either the wire won't push far enough into the screw-clamp connector or the insluation may prevent the binding head screw from pinching the wire - it'll pinch onto the insulation instead, making a loose, poor electrical contact.

And don't strip off too much wire insulation or the extra length of bare wire may cause a short circuit when you push the device back into its electrical box. That's more than embarrassing, it's dangerous. Trust me. Most light switches and receptacles include this indicator that tells you how much insluation the manufacturer recommends stripping off when wiring this device. It makes sense, then, to actually look at these instructions given by the manufacturer, as not all strip gauges show the same strip-back quantity.

If the wire is being inserted straight into the connector, push the stripped end into the connector skip our illustrations of making a hook or loop at the wire end, just insert the wire into the connector straight, as shown below, and go on to Tighten the Screw below. In the photo above I've inserted the stripped copper wire into the opening between the pressure plate and the backing plate of a screw clamp type connector on a 20A electrical receptalce.

I bend the wire into a loop using pliers. I like rounded needle-nose pliers for making a nice smooth hook. Tip: If I'm going to use the factory-provided bending lug to close this loop around the binding head screw stem then I make the open end of the hook a bit longer than shown in the photo above. That makes it easier to bend the loop shut against the lug as we will illustrate below. The hook is placed around the shaft of the binding head screw.

With the back of the receptacle facing you, place the wire on the left side of the screw so that when you tighten the screw by turning it clockwise the screw tends to pull the wire into the connection rather than pushing it out. Which wire is hot on a two prong plug? If for a two prong plug, the wider prong is the neutral, the narrower is the hot. The neutral wider prong gets connected to the ribbed conductor, the hot narrower prong gets connected to the non-ribbed conductor.

Which color wires go together? The protective ground is green or green with yellow stripe. The neutral is white, the hot live or active single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue. Does it matter which wire goes where on an outlet? For standard outlet wiring, the white neutral wire can go on either of the two silver terminals, since they are interchangeable. Likewise, the black hot wire can go on either brass screw terminal.

What happens if you wire an outlet backwards? This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. The other wire doesn't get connected to the earth, and it's called the ungrounded conductor, or hot wire.

How do you wire a 3 prong plug with 2 wires? An appliance with only two wires will be double- insulated not requiring an earth wire. Connect the two wires to the live and neutral prongs of the 3-prong plug. If the wires are color-coded, make sure to connect live to live terminal and neutral to the neutral terminal.

Under no circumstances should you ever remove the ground pin that sometimes annoying little third prong so it fits into a two-conductor outlet — it could cause you to get electrocuted. Leaving an open hot wire could cause problems in your wiring system. Beyond that, though, if a wire is not supposed to be open and hot , there is a risk that it could start an electrical fire.

Which side of a outlet is hot? Category: home and garden home entertaining. There is no positive and negative side in a standard volt AC wall outlet. The wider slot in the outlet should be the neutral side and the narrower slot should be the hot. Which is neutral in 3 pin plug? Is the big plug positive or negative?
