why do you use a contatcor and a timer?

you use a timer if you want to time something to come on and off at a certain time and you would normally use a contactor if what you are switching has a high start up current that the OCPD cant cope with or what ever you are wanting to use to act as the switch (in this case a timer) cant cope with the load so you use a contactor and a timer to switch the coil so the timer does not take the brunt.

Could you clarify exactly what you mean here? Because it reads like utter nonsense at the moment.

a domestic timer can only swich say 20amps max.

using it to swich a contactor/relay you can pull 100amp or more in using it.

You will take a L&N from consume unit and bring it to the time clock.

You will then take SWL from time clock to the contactor.

Connect aforementioned SWL to A1 and N to A2

Bring a permanent L and N to the N/O contacts of contactor and the SWL and SWN goes to light fittings.
