That's my understanding as well. So the stuff on the left is in the main panel? I thought the whole thing was describing a sub panel.I thought the neutral connection in the main panel can be connected to the the ground bus bar, just not in the sub panel where it has to be connected to a separate neutral bar right?

Yes, the stuff on the left is in the main panel.The GFCI is in the main panel, which connects to a 50A 14-50 stove receptacle. The control box will house the 3 pole distribution block, SSR's, DPST's, SPST's. The control box will connect to the 14-50 receptacle with a 14-50P plug.Looking at the diagram again it looks like I am connecting the neutral bus in the main panel to the neutral connection in the 14-50R receptacle, which connects to the neutral bus in the control box via the 14-50P plug. Hmm...That's my understanding as well. So the stuff on the left is in the main panel? I thought the whole thing was describing a sub panel.

Yes, neutral and ground have to be kept separate back to the load center. They are tied at that point. And with a GFCI breaker, neutral goes into the breaker and the breaker's pigtail then connects to the neutral bus. You may know this and understand it, but I figure I'd point it out nonetheless.Edit: Pic of what I'm talking aboutI thought the neutral connection in the main panel can be connected to the the ground bus bar, just not in the sub panel where it has to be connected to a separate neutral bar right?

I thought I understood this, but maybe not. Back to more research. And as a side point, rather than running the ground into the distribution block. Would I be better off running the neutral into the distribution block in place of the ground?Some of my planning has come from this diagram here.Yes, neutral and ground have to be kept separate back to the load center.

Boy, that's the truth. The inside of my panel will frighten the unprepared and terrify children.It bears mentioning, your control panel will get busy in a hurry, so pick one out and if space & budget permits, get a size bigger.

Thoughts?Next, you should add some down stream fusing to protect the wire gauge size and also the down stream componants.For instance; appropiate sized fuses for each of your pumps and sized fuses for your heating elements. Essentially to protect against a catastophic failure. (a heating element was to burn out and fuse to ground or a pump winding was to fail) This will also allow you to drop wire gauge sizes in each of the branch circuits.According to your diagram there is no branch fusing until the 50A breaker so the wire gauge size through out would be required to handle 50A before the jacket melts. That's some heavy gauge wire.

Actually the only place neutral and ground should meet is at the service entrance (main) panel, which is where they have to be bonded. If you've got a 240V subpanel/load center in the garage or something you need to have isolated neutrals and grounds in there and 4 wires back to the main panel.Yes, neutral and ground have to be kept separate back to the load center. They are tied at that point.

Well my 24x24x8 arrived last night. Holy mother of god. Just a tad too big, and too heavy. Weighs in at 45lbs! But it was a decent deal so I grabbed it just in case the 16x12x6 that I got for $20 isn't big enough.Nice price on the block. I never priced them for it was given to me. My CP is 10x10x6. Although it does house the 12 VDC power supply I have a separate box for the SSR's & disconnects. Maybe looking at mine and how much you plan on putting in yours will help you decide.I really love the idea my welding buddy came up with in regards to mounting the CP at an angle and on slides. It permits me to peak in the mash tun rather easily and it tucks away nicely when not in use.

I agree. This is why my elements and 120v stuff have their own breaker. They will trip at 30A and 15A in case of some kind of failure of a component or the GFCI.I had someone else mention to me the following, and I was interested on anyone's elses take on his comment.
That's what I'm saying. Load center = main service entrance panel. They are separate until you get back to this point.Actually the only place neutral and ground should meet is at the service entrance (main) panel, which is where they have to be bonded. If you've got a 240V subpanel/load center in the garage or something you need to have isolated neutrals and grounds in there and 4 wires back to the main panel.
