A lighting circuit would be a parallel circuit.
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
A "triac" is a type of thyristor designed for electronic control of the current supplied to a circuit, used especially in dimmers for lighting systems.
Usually 15A or 20A, but it depends on the wire used.
Use a # 12 exterior grade or romex
Can lighting and recessed lighting are often used interchangeably, but there is a subtle difference between the two. Can lighting refers specifically to the type of fixture used in recessed lighting, which is a cylindrical canister that houses the light bulb. Recessed lighting, on the other hand, is a broader term that encompasses any type of lighting fixture that is installed into a ceiling or wall, with the light source recessed into the surface. In summary, can lighting is a specific type of fixture used in recessed lighting installations.
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
In my opinion I would say not use use quoizel lighting for your patio. These types of lighting are more used for things like chandeliers. You could but if you can find something else, I don't recommend using this type of lighting.
Chystorama is a type of chandelier lighting for residential or commercial locations. It is a unique type of lighting that is often used by interior designers.
SF6 circuit breaker
block and tackle
you would use a parallel circut beacuse it will give it more power
This type of circuit would never be used. The two way fluorescent system would depend on the voltage being supplied by the two lamp circuit switch. If the switch turns off the two lamp circuit the rest of the circuit with the fluorescent fixture would become inoperable.
