Which is live on UK socket?

The UK electrical system is polarised. The earth pin on 13A plugs is at the top, they can only be inserted one way and the live is always wired to the right hole (as you face a socket). As the live is always connected one way, appliances are wired with this in mind.

Which is the live wire in a plug socket?

The wires. In a plug, the blue neutral wire goes to the left, the brown live wire to the right and the green and yellow striped earth wire to the top.

Which pin is live on a UK plug?

The Blue (Neutral) wire (bl = bottom left) goes into the hole in the bottom left (when the three pins of the front of the plug are facing away from you). The Brown (Live) wire (br = bottom right) goes into the hole on the right, connected to the fuse (which should be clipped in).

What colour is live on a UK plug?

What colour is the live wire? Live wire cable colours in the UK and Europe are brown.

What colour is live on a socket?

This replaces the old colours of red (live) and black (neutral) and green (earth) which changed back in 2006. If your plug has these colour wires, we recommend that you replace it.

British Plugs Are Better Than All Other Plugs, And Here's Why

Answered by Dave, Electrical Safety Expert

The live Red becomes Brown. The Neutral Black becomes Blue. The Earth wires continue to be Green and yellow.

What colour is switched live?

The brown wire is Live (also know as permanent live), this brings the live supply to the switch. The blue wire is known as the Switched Live and takes power to the light.

Is the brown cable live?

The brown cable – known as the live wire – delivers electricity from the power supply to your appliance. Together, the neutral and live wires form a complete electric circuit. The green and yellow cable is known as the earth wire, and it serves an important safety role.

What Colour is the live wire in a 3 pin plug?

A 3 pin plug consists of three pins (hence the name). Each pin must be correctly connected to the three wires in the electrical cable. Each wire has its own specified colour so as it can be easily identified. The LIVE wire is BROWN.

What happens if you wire a plug wrong?

But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

Which side of socket is neutral?

With American and Canadian plugs, if you look directly at a socket, the ground socket will be at a bottom, the live slot is on the right and the neutral slot is on the left. If the plug is polarized, the widest slot is the neutral connector.

Is black the live wire?

Black wires should always be considered live, so taking proper safety precautions is important to avoid electrocution. This includes shutting off the circuit breaker that supplies the wires you're working on, or shutting down the power to the whole house at the main electrical panel.

What happens if you touch a live wire UK?

You will receive a shock if you touch a live wire and are grounded at the same time. When a circuit, electrical component, or equipment is energized, a potential shock hazard is present. Black and red wires are usuallyenergized, and white wires are usually neutral.

How have wiring colours changed in the UK? The neutral black has been replaced by blue. The line red and has been replaced by brown. The earth is still identified by green and yellow.

Is the red wire live?

Red electrical wires are the secondary live wires in 220-volt circuits and are commonly found in a sheathed, multi-conductor cable. These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system.

Is blue active or neutral?

Blue = Neutral

The neutral wire colour is blue. The neutral wire transfers electricity away from the appliance to avoid overloading. It is located at the end of the circuit for connection after the electricity has flowed around the live and earth wires.

What colours are live neutral?

US AC power circuit wiring color codes

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.

What is common wire UK?

"COM" or "Common" is the terminal to which the live core wire is attached - this is the brown wire (formerly red). In photo B, you see a single, one-way light switch with old-coloured wiring.
