Question: How To Run Wire For Recessed Lights In A Finished Ceiling

How do you run wire for recessed lighting?

Can you put recessed lights in an existing ceiling?

Thinking about adding recessed lights or pot lights but don’t want to tear out your whole ceiling to do it? Luckily you don’t have to. With a little ingenuity and special remodeling housings, you can install a roomful of recessed lights or canister lights with minimal drywall tear-out and patching.

How many recessed lights can you put on one switch?

The main limitation on the number of recessed lights that a single switch can control is the rating of the circuit breaker controlling the circuit. Each incandescent or halogen 60-watt bulb draws around 1/2 amp, and therefore, standard lighting with a 15amp breaker can manage 30 lights.

Can I mix 12 gauge and 14 gauge wire?

It’s perfectly safe to use it. Don’t worry about confusing future workers. If they want to add something to the circuit, they will have to go turn off the circuit breaker first, and then they will see they are working with a 15 amp circuit.

Should recessed lights be wired in series or parallel?

Parallel. White to white, black to black throughout. If you wire them in series, you will only get a dim glow based on the number of units you wire in.

How hard is it to add recessed lighting?

It is more difficult to install recessed lights than traditional types. The process involves a lot of cutting out holes that are of the same size. Putting them in the ceiling can be even more challenging than working along a wall.

What is the difference between can lights and recessed lights?

Recessed lights, also known as can lights, are described as metal light housings installed in the ceiling for a sleek look that gives you back your ceiling.

Can you daisy chain downlights?

A daisy chain connects multiple light fixtures to the same circuit. It’s useful for recessed lighting, illuminating rooms, and connecting lights to the same switch. Run these new wires to the new light fixture and connect them. Continue this pattern until all the lights are installed.

Do downlights need a transformer?

Bulbs intended for use in wet zones (such as downlights in a bathroom) must be IP rated for such use. This means that each sealed bulb will contain a driver, with no external transformer required.

What cable is used for downlights?

For power sockets you’ll need 2.5mm and for downlights you’ll need 1mm or 1.5mm. Twin & earth cable which is available in various sizes. Known as 6242Y cable, it is used primarily for domestic wiring of switches, sockets and lighting. For power sockets you’ll need 2.5mm and for downlights you’ll need 1mm or 1.5mm.

How do you daisy chain LED recessed lights?

In the attic, run a wire from over the switch location to the first six-inch light, then to the next and so on until all six-inch lights are daisy-chained to the switch location. Daisy chain the two small lights back to the same location using a separate set of wires.

Can you use 12 2 wire recessed lighting?

Yes, it is okay to use 12-2 cable to supply lighting fixtures. The other answer indicates that it even with 12-2 you have to use a 15A breaker for lighting circuits which is not strictly correct. If the entire circuit is 12AWG (other than fixture wires), then a 20A breaker may be used.

Can you wire recessed lights in series?

If you will be installing recessed lighting, the wiring will have to be done in series for multiple light fixtures. Installing multiple recessed lights in a series is not difficult at all, and can be completed in a relatively short period of time. Wiring a series of lights is similar to wiring only one light.

How many lights can be on a 20 amp circuit?

Amount of Lights You Can Put on a 20-Amp Circuit Breaker With that fact, a 50-watt light on a 20-amp breaker can have a total of 38 lights on a circuit.

What happens if you use 14 gauge wire on a 20 amp circuit?

I would say 14 gauge wire anywhere on a 20 amp circuit is not OK. The purpose of the breaker is to cut off power before the wiring overheats. If you plug in several devices on an outlet that total 20 amps, you will exceed the safe working capacity of the 14 gauge wire without tripping the breaker.

What happens if wire gauge is too small?

What can happen when you use too small of wire size for your equipment? If too small of a size is used, the wire could melt because of the large amount of current flowing through it compared to how much the cables can handle. The smaller the wire diameter, the higher the resistance there will be to the flow of energy.

How far can you run 12 gauge wire on a 20 amp circuit?

You can run a 12 gauge wire up to 70 feet on a 15 amp circuit. That number drops to 50 feet if you run 12 gauge wire on a 20 amp circuit.

How many LED recessed lights on a 15 amp circuit?

Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.

Can you put lights and outlets on the same circuit?

Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes.

Are recessed lights out of style?

Recessed lighting will never go out of style. However, the finishes and sizes will vary and change as time goes by. There are too many advantages of having the lighting recessed for them to eventually go out of style or phase out.

How far apart should recessed lights be?

A good general rule for placement is to divide the height of the ceiling by two. The result is the amount of space to leave between each light. For example, recessed lighting spacing for an 8-foot-high ceiling would be 4 feet between each light. This will provide good spacing for general room lighting.
