The old UK colouring (still found in old installations) was black = neutral, red = positive, green = earth. The new colouring is blue = neutral, brown = positive, yellow and green stripes = earth.
With the new colours: on a UK 3 pin plug when facing the contact screws on the back with the cover removed: blue goes to the left contact as there is an 'L' in blue, and Brown is to the right contact as there is an 'R' in brown.
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
208/120 is typical for the US, so these are the colors for the US: A phase: black -------------------In Canada; A phase - Red B phase: red-------------------------------------B phase - Black C phase: blue -----------------------------------C phase - Blue neutral: white -----------------------------------neutral: white ground: green or green with yellow stripe
Blue, Red, and yellow are the 3 primary colors.
The shield wire is not the neutral wire. You will need to connect the black and red wires to the hot terminals of the stove plug and the shield wire to the ground terminal. However, it is advisable to consult a licensed electrician to ensure proper and safe installation.
In the UK, the colours were once black = neutral, red = live, and green = earth. The modern standard colours are now blue = neutral (note the l in blue for left contact in the three pin plug used in the UK), brown = live (note the r in brown for right contact), and green and yellow stripes = earth In the US, black= hot wire, white= neutral, green or bare= ground (or earth) red= a second hot wire
the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
red is positive and black is neutral...if the wires are red and black.
Red - active, (commonly known as your live cable) Black - Neutral Green - Earth
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
208/120 is typical for the US, so these are the colors for the US: A phase: black -------------------In Canada; A phase - Red B phase: red-------------------------------------B phase - Black C phase: blue -----------------------------------C phase - Blue neutral: white -----------------------------------neutral: white ground: green or green with yellow stripe
In an electrical circuit, the red wire is typically considered the hot wire, while the black wire is usually the neutral wire.
red = phase, black = neutral, green = earth
Blue, Red, and yellow are the 3 primary colors.
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
