Wiring a lighting circuit

In above fig, all the three light points are connected in series. Each lamp is connected to the next one i.e. the L (Line also known as live or phase) is connected to the first lamp and other lamps are connected through middle wire and the last one wire as N (Neutral) connected to the supply voltage then.

Does a lighting circuit need to be a ring?

Ring circuits for lighting are totally unnecessary.

Which wires go where in a light fitting?

If the light fitting you have purchased has just two cores - live (brown) and neutral (blue), connect the live to the switch live terminal and neutral to the neutral terminal. If the fitting has an earth core, it must be sleeved with a yellow and green coat and connected to the Earth terminal.

Is common L1 or L2?

A one way light switch has two terminals which is a common marked as COM or C. The common is for the live wire that supplies the input voltage to the switch. The other terminal is marked as L1 and is the output to the light fixture.

Should lights be wired in series or parallel?

The common household circuits used in electrical wiring installation are (and should be) in parallel. Mostly, switches, Outlet receptacles and light points etc are connected in parallel to maintain the power supply to other electrical devices and appliances through hot and neutral wire in case if one of them gets fail.

Should I wire LED lights in series or parallel?

Series, Parallel, or Series/Parallel? The requirements of a lighting application often dictate what type of circuit can be used, but if given the choice, the most efficient way to run high power LEDs is using a series circuit with a constant current LED driver.

How many lights should be on a lighting circuit?

There is no limit to the number of lights on a circuit. The load of the fixtures is what determines how many lights a circuit can accommodate. A conventional 15A circuit can have up to 1400W of lighting loads connected to it. A 1400 Watts lighting load can accommodate one 1400W fixture or fourteen 100W fixtures.

Can I use 2.5 mm cable for lighting?

2.5mm is commonly used for behind sockets, while 1-1.5mm is most often used for lights (depending on how many lights you have in a circuit).

What size cable is used for lighting circuits?

Lighting circuits are generally run in 1mm2 two-core-and-earth cable, but particularly long circuits can use 1.5mm2 cable to compensate for the drop in voltage experienced on long cable runs.

What happens if you wire a light fitting 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.

What Colour 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.

What color wires go together for a ceiling light?

Light fixtures with more than one lamp may have a pair of black and white wires for each lamp. These connect to the black and white wires in the electrical box with the provided larger wire nuts. Motion lights have black, white and red wires. Black and white always connect to black and white.

What wire goes to L1 L2?

Typically, these terminals will be marked COM and L1, or sometimes L1 and L2. Either way, it does not matter which wire is connected where. Usually the permanemt live (from the supply) is connected to COM and the switched live (to the lamp) is connected to L1.

Does L1 go to black or red?

The faceplate of a single, one-way switch has two terminals: "L1" is the terminal to which the neutral core wire is attached - the blue wire (traditionally black, before the change). "COM" or "Common" is the terminal to which the live core wire is attached - this is the brown wire (formerly red).

What does L1 L2 L3 L4 mean on a light switch?

These have four terminals and are equivalent to two 2-way switches combined. There are various labelling schemes but L1, L2, L3, L4 is common. In one position L1 connects to L3, L2 connects to L4. In the other position L1 connects to L4, L2 connects to L3. Used where three or more switches control the same lighting.

Which is better parallel or series circuit?

A parallel circuit is better than a series circuit because in case of any failure only the appliance connecting the faulty pathway will stop working. All the other pathways of the circuit remain unaffected by the failure.

Is it OK to wire lights in series?

Wiring lights in series is not something that is done in normal practice, especially in home wiring. If you are not looking for information about wiring lights in series, but rather wiring a series of lights together on one circuit, the way the lights are connected is a parallel arrangement, and not series.

How do you wire multiple lights to one switch?

You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a "home run" configuration.

What happens if you wire a LED light backwards?

LEDs, being diodes, will only allow current to flow in one direction. And when there's no current-flow, there's no light. Luckily, this also means that you can't break an LED by plugging it in backwards. Rather, it just won't work.

How many LED can be connected in parallel?

Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply. We could take those same four 3V LEDs and wire them in parallel to a smaller power supply, say two AA batteries putting out a total of 3V and each of the LEDs would get the 3V they need.
