    Hi
    The first time I connected the circuit short-circuited when I connected to the LNE 230v now I changed the circuit board and connected to rt 230v but there is no power have I connected something wrong?

    Last time I connected to the LNE it had short circuited and the circuit breaker tripped. My input voltage is measuring 253V could this be the reason it short circuited?

    the L&N you have in RT go into L&N in the 240v connector next to it, and whatever that yellow wire in N is should not be there(I suspect it should be in the RT but you will have to find out where it comes from ) good chance you have damaged the new PCB
