Default starting my build

I am starting to put together my electric brewery after months of reading on here and asking questions. It will be a 2 tier stand with 5500w elements in 2 keggles(HLT and BK). I will be using a cooler for a mash tun with one pump. I plan to expand to a HERMS system with 2 pumps later on. I am going to use this schematic and just slightly modify it. Even though he didn't draw it for me I would like to thank P-J for the time he put into this.

I will be using 2 auber 2352 PIDs and eliminate the flashing buzzer. I still have a few questions:
1. Would these work for distribution blocks?

2. What size wire is needed for the emergency stop?
3. Where is a good place to buy fuses, fuse holders and resistors?

Any help is greatly appreciated.

electrical stuff like wire and breakers/din rails can be found at places like digikey, newark, and mouser. Ebay and your local electrical supply should be able to help with some stuff too. The wire for the estop does not have to be very big. Current is what dictates wire size and if you are using PJ's estop that circuit wont pull more than 1 amp.

Check this chart out for future questions about wire sizing - http://www.powerstream.com/Wire_Size.htm. I would go with the chassis wiring column.

Those distribution blocks would work fine. Just make sure you get them for the right wire size and current draw you expect. I got mine from mcmaster-carr and i think you can get stuff like that from places like newark.com if you wanted to combine the order with other things.

How many volts do the fuses need to be rated for?

how many volts will you be hooking up? 120? 240? most fuses are rated for high voltage. You need to be most concerned with current for fuses and breakers, although it is worth verifying the voltage limits.

I will be hooking up 240 to the control panel. I am finding most of the small fuses are for 250v so am I correct in assuming those would work?

So my package from Auber came in but the window was closed at the post office. I'll have to wait until this afternoon to pick it up.

I think I am going to use these for my fuses:
fuse holders:
http://www.radioshack.com/product/index.jsp?productId=2102786
Says it accepts up to 18 gauge wire, don't know if that would be a problem or not. Maybe I could use this instead:
http://www.radioshack.com/product/index.jsp?productId=2102782

fast acting fuses:
http://www.radioshack.com/product/index.jsp?productId=2102739&filterName=Type&filter Value=1.1-2A

Slow blow fuses for E- Stop:
http://www.radioshack.com/product/index.jsp?productId=2102747

Now to figure out resistors

Got my keggles all drilled and cleaned up the metal shavings and oil and installed weldless valves, pickup tubes, and sight glasses from BrewHardware.com. After getting everything put together I realized I still need to drill holes for the elements.
