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.

why do you use a contatcor and a timer?

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.

Send a PM to Paul M or Sintra or Marvo and they'll guide you through the process.

It's not a crime to admit that you are out of your depth matey.

Especially as a trainee.

knowing your limitations and working within them is a skill in itself.

 

[AlexGoode]

I will happily admit that I am in no way an expert with contactors and alike but i feel (and as others have also told me in some cases), the best way to learn is from mistakes and trying it yourself. Trev, who is paul m, sinter and marvo?

Well TBF the best way to learn is from other peoples mistakes.

All the advice from people who have already made those mistakes and rectified countless more of other peoples mistakes is ????

I thought I heard my name being mentioned

You can apply to join our trainee forum which is free and no strings attached. There's mentors there who will assist with an electrical related questions or problems. Please read this thread and do the necessary so we can consider your application.

If you need a basic explaination how any electrical component works then wikipedia is a good place to start or there's a free publication called 'All About Circuits' which is pitched at a suitable level for learners.

Mate, you're an apprentice. A fairly new one by the sounds of it so you're not an expert in anything yet.
Walk before you run.
By all means learn from mistakes but those mistakes are best made under supervision so the person doing the supervising can tell you where you went wrong and how to put them right. As I've said several times, if you do this job I confidently predict a lot of problems for you.
You're not ready for this.
Yet

Learn to swim before you dive in, there is no shame in telling your mate your still learning and don't know how to do it, the thing about electricity is it can kill... competence before pride always is my best advice!
