Sorry if question was badly explained .
I have an existing installation to test and a new installation to install but not really sure how to wire lights to contactor last time i came near one was dol starter AM2 20 yrs ago spent all my life doing domestic installation and testing

That's all a contactor is, a starter without the overload protection. Just connect the supply and the load to the contactors contacts positions, and the means of switching on and off to the coil contacts....

yeah but would you not need 10 contacters one for each bank of lights or am i missing something

How are the contactors being switched? You can get 4 pole contactors, so you can run 4 circuits through that contactor. Just depends if you want four lots switched on at once.

thats what i dont understand each bank of lights has its own switch on the existing installation so should there be a contactor for each for each bank of lights i have a photo of existing control box but dont understand it is there a way to put it up for people to view

Use a website called photobucket, upload it to that. Inless there linking the all the contactor coils together and switching it using something else, for example a timer, and then using the switches to control the feeds to the contactors. Meaning you can only turn the lights on once the timer pulls in the contactors.
