I finally have made all of the large purchases for my Kal mutation and will document progress here as well as ask for lots of help.

My rig differs in that I am building a panel capable of firing two 5500W elements simultaneously. Minor differences are that all my relay coils and my pumps are 240V so my wiring will differ significantly.

The last change is that I am hoping to use the pictured 6500W thyristor from ebay to control my Boil Kettle. In trying to trim expenses where I could, the thermocouple and PID seemed unnecessary. Plus I wanted something to be unique.

I am confused that is has 4 terminals. Do you think i run both legs throught it? I unsoldered the potentiometer, because I didn't have room to mount the whole unit to the door of the panel.

Has anyone used one of these? Can anyone offer advice? Thanks. I also included my planned component placement for the heck of it. Happy for advice there too. Thanks!

I have one of these units. A 6500W rated one for a 4500W element.

Yes you run both hot legs into/out of the unit.

THANK YOU! Can you be more specific just to make sure I don't screw anything up? I am assuming the hot legs go IN to the "L" terminals and come out the "N" terminals?

Thanks again SO much. Do you see any problems with me moving the pot somewhere else and just running leads from it to the PCB?

I'm guessing you go in on one side and out the other. L and N signify the wire (Hot A / Hot B) and the writing above would tell you which side is line and which side is load. I can't read whatever language that's written in though...

Nice buil BTW. I just spent sometime enjoying your work. So, after a little thought and observation, I think only 1 leg needs to go through the unit. Check my thinking. In the underside of the PCB, the two "N" terminals are connected by a line of solder. The underside does show the terminals connecting to something else, but nothing is there... So it looks like whatever is connected to the N terminals might as well just skip the board.... See photos. I am reading PCB correctly?

Definitely looks like solid logic there. Not sure which side would be Line or Load, but I have to agree that N appears to be a simple through-put line and could be skipped given that it doesn't seem to connect to anything else.
