Ok so I am sorting out the supply side of my new system up to the Control enclosure. I put together the diagram below.
Since the links are not clickable in the jpg here they are again. These are examples. Some of the items are already sourced, some I will pick up from Lowe's/Home Depot/Amazon ect.
1) Cuttler-Hammer 50amp Double Pole breaker in the open spots in my main panel.
2) 6/3 Romex in the wall feeding my spa panel.
3) 50 amp Spa Panel
2) 6/3 Romex in the wall feeding an outlet.
4) 50 amp dryer/welder outlet.
5) 6/4 SOOW wire
6) Dryer/Welder plug
7) Leviton 2713 Locking Connector
8) Leviton 2715 Flanged Inlet Locking Receptacle.
9) Leviton 2710 Flush Mounting Locking Receptacle X2
10) leviton 2711 Locking Plug X2
Now my questions or concerns with my setup.
A) This setup is 50amp rated all the way up to the control enclosure receptacle. I did this just in case some moron purchases my home later and decides to hook up something that draws 45 amps to the spa panel outlet and burns down the house because I used 10/3. I do not want it to fail any home inspections or code inspections. Anyone see a problem with the layout up to the outlet other than the cost of 6/3 over 8/3 or 10/3? I would also not mind being able to run my welder off the outlet when the control panel is not plugged in.
B) My system will be 3 vessel, 2 element (5500w ULWD), 3 pump, BrewTroller controlled. I will only be running 1 element at a time. Is there any problem using the 30amp rated Leviton connectors on the ends of the 6/4 SOOW? I already have the 6/4 SOOW considerably cheaper than buying 10/3 or 8/3 wire and would like to use it.
C) Do I need to have a 30 amp breaker somewhere after the dryer wall outlet? I will be using 10mm 65amp 10-6 DIN Rail Terminal Blocks inside the enclosure for each leg of the service. http://www.mcmaster.com/#catalog/119/749/=m5wjnb
D) Open to input if you see a problem!
