Timer and contactor

[Jamzie]

I hear what your all saying. Only intention was to educate, not to send someone on a suicide mission

The damage is done, think before giving advice to people. The OP is clearly out of his depth and a danger to himself and others.

 

[Diddy]

We all tread a fine line when giving out advice. I think no matter what anyone says here that the op is going to do this on his own.

So do I Dave but the more advice he gets (other than don't) the more confident he will be.
I hope it won't end badly but I suspect it will

 

[AlexGoode]

seen the guy today, told him what you suggested, that i won't do it but can you at least help me understand as that type of work is hard to find where i work

Alex,

From your description, it’s a very basic contactor circuit. One, which probably can easily be found if searched for on google or in a basic training manual. There are assumptions made here due to lack of information:

The contactor coil pins, A1 & A2 are connected to the timer, so when the N/O timer contact closes at the required time, the contactor coil will be energised. The two N/O contactor contacts (pins 1&2 and 3&4) will both close when the coil is energised. Therefore live (pin 1) will supply pin 2, so supplying live to the lights. Neutral (pin 3) will close the circuit with pin 4.


Edit:Typing '2 pole contactor circuit' into google revealed plenty of examples...sorry but its really not hard.

I would suggest going to Maplins and buying some 12V DC relays and play with these using a power supply and some lamps. Won’t cost much but will be educational, safer than playing with mains.

You Barribon Buffoon you

so why when i had a look, would there be a supple live to both the timer and the contactor- terminal 1

 

[AlexGoode]

why use a contactor rather than just the timer?

Because you don’t know what you’re looking at.

Keep your fingers out of it and get an experienced electrician to teach you how the circuit works.
