I mean obviously it's dangerous trying to manipulate electricity wirh such a high voltage
But what I meant is, will the relay handle the voltage and the current? Like, is it do-able?
I will repeat what I said earlier
If you ask this question I think you need to get a qualified electrician to help you to do things safely.
I am not prepared to give advice in case my unqualified advice is incorrect or, if it is correct, in case you misinterpret my advice and cause harm to yourself, someone else or your property.
