How big of a boil are you doing? I have a 60 gallon BK & MT but my HLT is only 20 gallons so I can't actually brew 2 barrels at once but We just did a 32 gallon boil this weekend with 2 - 5500 elements and had plenty of power to do more... I'm not sure if we had enough to do 60 gallons or not but once we got a nice rolling boil I was able to cut the elements down to about 62 % and maintained a nice rolling boil, boiled off 32 gallons down to about 27 gallons with a 60 min boil. I am running the system off of a 60 amp breaker in my panel running a 60 amp GFI panel and had no issues. P-J made up the schematic for me I gave him a description of my system and he put an amazingly easy to follow schematic together I'll attach it. P-J is the man
I think you will need more than 11,000 watts for a 62 gallon batch (about 70-72 gallon pre boil volume). I brew 35 gallon batches (42 gallon pre-boil volume) with 9000 watts in my BK. I have to run it at 90% power after I reach a boil.
Actually 11kw does just fine, I boil 73 gallons with it. 2 5.5kw at 95% power. I get low boil-off, but the boil is fine and quite active.
I wired a control panel for my 2 bbl electric brewery, but used 5 separate gfci's from the main panel. From there is conduit into the brewery to my CP. This turned out much more affordable and allowed me to use only 10 awg max, and avoid any expensive industrial gfci's. I can also run 22,000 watts fully on all at once.
Edit: The 5 gfci's include one 20 amp single pole along with the 4 30 amp gfci's for the heaters.

To use 60a gfi's would require more wiring, more components, not less.
Firstly the bundle of 10awg wires was run through the conduit together and presented no issues.
Second if I ran 2 60amp lines to the control box, I'd need additional circuit protection in the box, on top of all the components in there presently. There would not be room in this box obviously. Plus it would require additional wire sizes run etc. Easier and cheaper to buy one roll of 10 gauge wire.
The fifth gfi is a dedicated 120v circuit, feeds the pump and the 12v transformer/bcs.
Is there more then one 240 circuits? And if so would you happen to know the max continuous amps on the circuit(s)?
As I read that diagram, it's fed by a single 60-amp 240 circuit.Is there more then one 240 circuits? And if so would you happen to know the max continuous amps on the circuit(s)?
That is absolutely correct.Is there more then one 240 circuits? And if so would you happen to know the max continuous amps on the circuit(s)?

That is absolutely correct.
Also, there are circuit breakers in place to protect the various devices. The max amp draw is the acculimated total of the devices being used. Keep in mind that switch #6 allows either the HLT - Or - BOIL elements to be powered.

So with this using multiple circuits idea, would it be possible to use two 20 amp circuits to power one 5500 watt element? Or is there not a way to run them like that?
Just to confuse matters, another approach would be to wire the switches and contactors to the heating elements to achieve 4 states:
1) All off
2) Both on in the BK, both off in the HLT
3) Both off in the BK, both on in the HLT
4) One on and one off in the BK, one on and one off in the HLT
