Where would i use a lighting contactor?
Answer:
Lighting contactors are used to turn on and off lighting loads that operate at a higher voltage or current than is desirable of feasible to control with an ordinary wall switch. That could be a few powerful lights or all of the lights in a large room controlled by one switch.
A contactor also allows relatively simple switches in any number of locations to all control the same lights. The switch is a momentary contact switch which closes one normally open (N.O.) contact when pushed in one direction and opens one normally closed (N.C.) contact when pushed in the other direction. Springs return the switch to the center position in which the N.O. contact is open and the N.C. contact is closed. All of the N.O. contacts are wired in parallel and bridged by an auxiliary contact on the contactor. All of the N.C. contacts are wired in series with each oher and with the N.O. contact group, that entire group is connected between the control power source and the contactor coil. The other side of the contactor coil is connected to the other side of the control power. The required type of switch is available in the style of ordinary light switches.
to put your lights up.
Lightning conductors are normally only used on high buildings such as churches in order to protect surrounding areas. The idea is that the electrical charge runs down the lightning rod into earth and lessens the chances of people or buildings being struck.
Lighting contactor are generally used in lighting for growing plants in green houses and the like, there used i think using some kind of witchcraft (i dont know the technical speak) to regulate the power when you turn the high wattage lighting systems on. A garden centre would be a good source of info
you can install a lighting contactor if you want to control multi lighting bays with only small switch like a toggle switch, or if you want to control your yard lighting with a photocell, you need only one photocell to control your lighting contactor that controls kilowatts of lighting.
Anywhere you want to control many circuits with a single input.
Eg.s : Warehouses, green houses, site lighting, theaters.
