This is an updated version of the first arrangement.
Lighting circuit cable.
Used to make the electrical connection between loudspeakers and audio amplifiers.
The consumer unit is normally connected to the first lamp which in turn is connected to the second lamp and so on.
Unlike the ring power circuit the lighting circuit does not form a loop returning to the consumer unit.
There are some useful guides and further advice on electrical safety and individual appliances here.
Usually called cat 5e or ethernet cable.
These days the loop in system predominates though individual circuits often combine the two for the most economical use of cable.
Three core and earth cable.
The cable used is a 1sq mm pvc twin core and earth rated for up to 12 amps.
The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer remote control or other programmable switch.
There are many types of cable used to keep a building running choosing the right type and size of cable for the job is critical.
All the factorylux power cable has 1 5mm cores and is rated up to 15 amps.
The cable consists of 4 cores with 1 being the neutral and the other three potentially being live depending on the way the lighting circuit is designed and what position the switches are in.
A lighting circuit can serve up to 12 x 100w bulbs.
Category 5e cable.
Electrical safety first.
Cable will be used for lighting.
This does not include the light switches which should be wired in switch wire which contains 2 red cores.
Although described as lighting cable the 0 75mm flex can be used for appliances rated below 6 amps or 1 380 watts.
Lighting circuits are wired in two different ways using either junction boxes or loop in ceiling roses.
This type of cable is used for wiring two way light switches.
Unlike power circuits lighting circuits are always of the.
Running a series circuit helps to provide the same amount of current to each led.
Because the electrical code as of the 2011 nec update requires a neutral wire in most new switch boxes a 3 wire cable runs between the light and switch.
Type two lighting circuit.
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.
