Are you trying to wire a switch or outlet? You cannot proceed without first identifying the various terminals and determining the roles they play. Switches and outlets can still work if you connect the wires to the wrong screws. But a poorly wired outlet is a shock hazard.
What Wire Goes To Gold Screw?
A Hot wire goes to the gold or brass screw but it has some exceptions:
- You don’t have to concern yourself with neutral wires in a single-pole switch. You have two terminals that connect to the hot wires. These interchangeable terminals are the same color (Brass).
- From the description given by Stanley Tools, you can see that a three-way switch has two brass screws that connect to the black or hot wires. In a four-way switch, you have four brass screws.
- Outlets have two brass screws that connect to the hot wires. You don’t have to connect a hot wire to each brass terminal. If the electrical box has one hot wire, connect it to one brass screw. You can ignore the second brass screw.
Don’t expect manufacturers to use a black or red color for the hot wire in every situation.
Some switches use the white wire as a hot wire. This can cause an experienced technician to wire a switch poorly because their experience taught them to view the white wire as neutral.

Is The Gold Screw Hot or Neutral?
The black or red wire – the hot wire – connects to the brass or gold screw. This tells you that the gold screw is the hot terminal.
On Electrical, What Wire Goes To The Silver Screw?
The white wire connects to the silver screw. The white wire is the neutral wire that takes the unused current back to the breaker panel.
Is The Silver Screw Hot Or Neutral?
If the white wire is the neutral wire, the silver screw is the neutral terminal because the neutral wire connects to the silver screw.
The neutral wire, which can be gray, is essential because it allows the current to circulate through the circuit.
Some technicians can use the neutral wire as a hot wire. But you have to mark the wires with tape to prevent people from confusing the white or gray wire for the neutral wire.
The neutral wire can electrocute you if you mishandle it. But for the most part, it is safer than a hot wire. That isn’t true for a neutral wire you use as a hot wire.
Don’t expect to use the neutral wire in every single situation. For instance, single-pole switches don’t have a neutral terminal. They use two terminals for the hot wire and a ground screw.
An outlet, on the other hand, has two silver terminals. But you don’t have to use them both, not if you have one neutral wire.
What Color Wire Goes To The Common Screw?
The white wire connects to the common screw. This is because the white wire is the common wire. Therefore, you have to match it with the common screw.
Is The Common Screw Hot or Neutral?
To understand the common screw, you must first understand the common wire. Common wire is the white neutral wire. You find white neutral wires tied together in circuits in the United States.
The hot wire brings the current from the power source to the outlet in a circuit. You need a wire to carry that electricity back to the power source. The common or neutral wire performs this function.
You can use the common wire as the ground wire. But this practice, which is called bootlegging, is dangerous, so electrical professionals discourage its use.
Because the common wire is the neutral wire, you have to call the screw to which it connects ‘Neutral.’ Common terminal is darker than the other terminals.
You will see this in a three-way switch with two screws with the same light color and a single terminal with a dark color.
How Do You Know Which Color Wire Goes To Which Screw? Is There Any Rule?
Most electricians follow the same standard, which associates black or red with hot wires, white with neutral wires, and green with the ground connection.
The people at BRADY have observed the same standard within the documentation of the NEC.
Black should indicate the hot wire, which carries electricity, whereas red should signify the secondary hot wire. Green and copper are the ground conductors, whereas white points to the neutral cables. You can use blue and yellow for the hot wires as well.
However, from what Dave Farquhar has seen, there are no definitive rules regarding the colors of the wires and the screws to which they connect. Many people live in houses whose electrical boxes are filled with cables with all sorts of colors.
Many settings use the same three or four colors. But if you see more colors than that, you should seek professional help.
Europe is different. UK relies heavily on the BS7671 Wiring Regulations (17th Edition). The goal in the country is to maintain consistency with International Standard IEC 60446.
British authorities expect their electricians to use black (or blue) for neutral, red (or brown) for hot, and green or yellow for the ground. If you work in the electrical arena, you already know the colors you expect to encounter because you see them every day.
This issue is only confusing if you move to a new region with a different color scheme.
What Happens I Connect Wrong Wire?
Improper wiring can reverse the polarity. This is where the current flows in the wrong direction. You will energize the wrong sections of an appliance, which leaves you vulnerable to electrical shock.
This is the worst-case scenario. In the best-case scenario, the outlet or switch won’t work. Though, an inoperable outlet or switch can still shock you.
Safety Measures
Outlets and switches are not particularly complicated. However, you can still shock yourself or start a fire if you mishandle them. Keep the following safety measures in mind whenever you install or replace switches and outlets:
1). This goes without saying. You have to cut the power before you proceed. Switch the power off at the breaker. This is the only way to guarantee your safety.
2). Don’t assume that the wiring is safe simply because you cut the power at the breaker. Use a tester to check for the presence of a current. Don’t touch the wires until the tester has confirmed that they are safe.
3). Take a picture of the wires before disconnecting them from the screws. This will remind you of where everything was before you dismantled the outlets and switches.
4). Mark the wires with tape if you have difficulty remembering the function each wire plays. You should also do this whenever you change the role of a wire.
What about Switch – What Color Wire Goes To Black Screw?
The common wire connects to the black screw.
You cannot wire switches and outlets without knowing the standard color scheme most circuits use. Admittedly, some manufacturers do not always adhere to this standard.
But it helps to know the basics. For instance, you usually have a hot, neutral, and ground wire. The hot wire is either red or black, and it carries the current to the device you want to operate.
The neutral wire is white, and it carries the power back to the source. Then you have the green or copper wire, which works in tandem with the grounding system. Identifying the wires and their colors is the first step. But it isn’t enough.
You need to know where each wire goes and to which terminal or screw it connects.
If you don’t have confidence in your abilities, you should hire an expert to replace your outlets and switches.
