Lighting Circuit

My My

Well you have a 3 core cable coming from the photocell (including earth) which is installed in an area with good day light outside. This cable used is down to ur design spec!!!!

The photocell!!!!!

1 core is the swich line back from the photocell to the coil normally labeled A1 connected on the contactor, ( don't forget the brown sleave the cable)

2nd core is gona be sleaved blue and connected on the neural bar, where is up to you becasue you might have it Rcd protected on the photocell ETC. If this is connected wrong then the RCD will detect an unbalanced neutral and trip!!

3rd core is the perment feed that is feed from your overcurrent protection device form your consumer unit stright on the the photocell this feeds the photocell so it can monitor the daylight permantlly. What amp rated device for the photocell is up to you and you design spec!!

secondly you have the Live-Neutral feed from your overcurrent protection device in you consmer unit feed the contactor on one side. The load of which your photocell is switching the coil is connected on the load side of the contactor.

EASY!!!!

Contactor

Then connect a neutral on the terminal Label A2 on the contactor, now if the photocell is RCD protected etc then is neutral must also come from the RCD neutal protected bar from the comsumer unit. If the photocell is just on a normal (unprotected) side then a neutral is taken from the normal neutral bar.

To be honest to explan it better and more detail we would need to know exactly what your are trying to acthieve to relate to task in hand I.e what equipement you are using.

Make sure everything is fused down the approprate Amperes rating aswell

hello dear

i wish if i can help u

so pls tell me what is ur problrm exactly

installation or wiring

thx

SnakeMike, Is this an industrial application or for home use -- more details please. What voltage/wattage? Incandescent, fluorescent, HID? Indoors or outdoors? All this wiil make a difference in your system design.

Go to Home depot, Menards or any other major lumber type yard, and find a photo senson light to do what you want. They are available to do most any job and aren't all that expensive.

I would go to my local hardware store and buy one, then reverse engineer it for the grade.

I don't want to be a wet blanket but if you need to ask how to do it you probably would be wiser not doing it. E.mailed answers can't make up for experience.

Whats a quid and a bob? Sounds like a snack!

Respectively one pound sterling and one shilling (1/20 of a pound from before decimalisation) or 5 pence today!

I reckon you'd be struggling to get a snack for a quid these days. Sorry, my quotation is a little dated. Perhaps I should upgrade it to "An engineer is the person who can do for a few grand what any fool can do with ten million bucks of government money"? I'm open to suggestions!

or know how, and do not forget safety as I asume that you will use the mains supply.......

This is basically a very simple circuit. The photocell controls the contactor coil and the lights are connected through contactor contacts. A 2 amps fuse/circuit breaker should protect the coil and the size of fuse/contactor for protection of lighting circuit depends on the actual load. If you want me to send you a circuit diagram, send me a note to, zell_bosak@bigpond.com.

THE CIRCUIT HI IAM SO GREATFULL FOR THE HELP PLEASE SEND ME DIAGRAM.

I'm not an electrician, my son is & my brother are licenced contractors & I know a fair bit about basic electrical circuits, light & power etc. around the house, 240v ac. When someone asks me about how to wire up something or replace a power point or whatever , I know straight away they haven't got a clue & I DON'T TELL THEM ANYTHING !!!!! because you can be legally liable if you give the wrong advice or they misinterpret the advice & "zap" themselves working on something which should be done by a licenced qualified electrician, often the local, state or federal regulations specifically ban" playing around" yourself on most electrical installations.

If you don't know then hire a "sparky" to do the job, is your life only worth the $100.00 or so you might save ??
