Do you have enough knowledge about circuitry to comment on my wiring diagram above? PJ seemed to indicate it's a mess and judging by what I've read on here he seems to be the resident expert.
WRONG.!

You did a good job.

(Sorry about the diversion for you.)

Awesome! Just took a lot of searching through the forums for me to get what I needed (and a few home brews to allow me to be patient enough

So that contactor that I linked to is good?

The contactor is A-Ok. It is a good choice.

The suggestion to power the PID from the same outlet is valid. I would also suggest doing that. The PID draws less than an amp of current. No problem.

Sweet, thanks.

Two more questions for the crowd:

I'm planning on converting a (plastic) toolbox into my control panel.

1) Should I look to keep my heat sink on the outside of the toolbox (searching for the forums from similar builds I saw people putting it on the outside but don't know if a 2000w element would produce less heat than a larger watt element)

2) If I don't really want to drill holes in the bottom of the toolbox to mount my parts, could I just use a piece of wood that's formed to the shape of the bottom of the toolbox or should I use some sort of metal?

I would suggest mounting the heat sink on the outside of the controller. This way the heat is dissipated to the room instead of being contained & effecting everything else.

Mounting the components to a thin piece of plywood is Ok. No problem. Most all of the components used in your build do not have any ground bonding to its mount.

Go for it.

Hope this makes sense and is of some help.

Ok I lied when I said last question before

For the power going to the element, can that be grounded to the nut on the element itself or does that need to be grounded to the kettle?

Yes. That is ok as the element is then bonded to the kettle.

So just thinking through mounting my heat sink on the outside of the tool box.

I'm trying to figure out the easiest way to do this. I'm going with the tool box solution because (among being cheap) it's easy to just close it up and put it back into storage. So if I'm going to have the heat sink on the outside of the box, I want it to be easy to put right back into the box when finished.

Ideas I've had so far:

1) Mount the heat sink to the inside lid of the box. I would be ok with a more permanent mounting here as long as I have the room to just close the box back up easily with the sink mounted.

2) Mount is somewhere to the side. Problem here is I want a way that I can easily just grab the heat sink from where it's mounted and put it back into the box. I don't really feel like screwing and unscrewing it every use. It wouldn't be the end of the world though.

3) Just don't mount it. I could just have it that I just take it out of the toolbox and place the sink next to the toolbox when I'm using it.

Anyone have any input? Leaning towards 1 right now.

Find a way to mount it an keep it there. Moving parts around is likely to lead to loose connections, a wire getting snagged on something or some sort of failure.

The heat sink has the SSR(s) attached to the back, the SSR(s) have power lines and signaling lines running to them. Trying to move the heatsink around means moving all of this. Not a good idea.
