High voltage plugs/inlets question - Page 2

**Budzu** · 10-31-2009, 05:06 PM

I'm bringing this thread back up as I've just acquired all the breakers and wiring equipment to run my subpanel. The power to my brew system will be supplied from a Siemens 60 amp GFI breaker, which is situated in a 125 amp lug panel. I will run all the system power, including 120v, from this source.

I now need outlets and wiring. From the 60 amp gfi breaker, I will run 6 gauge copper to this outlet: http://www.levitonproducts.com/catalog/dept_id_985/model_9460.htm The power needs for this outlet are:
1 5500 watt 240v element
1 24vac transformer (panel switches)
1 12vdc transformer (brewtroller power supply)
2 march pumps

Before I pull the trigger on these components, does anyone see anything wrong with this application? Will the GFI be able to function properly while supplying both voltages?

Thanks so much in advance and cheers

75% of the service is being used by the elements and your transformers will be negligible, Plus the pumps and I think you are good for the service. Yes, the GFCI will be able to supply split voltages, just remember to run #6 3-1. Be fore warned, March pumps don't always play well with GFCIs. Some seem to leak a bit of current to the chassis causing it to trip.

Thanks CR

So you mean running both elements at once is ok with 60 amp service? I was debating that, since its so close to its limit. I will have two elements but its no problem to wire in a DPDT as a selector switch for supplying current to only one element at a time. But running both would make strike water heating alot faster.

Both elements running at the same time you are pulling a little over 45 amps. You're even under the magic NEC 85% 3 hour continuous load rule.

Man, you will heat some strike water up FAST with 11kW on a 5 or 10 gallon system. One element would be plenty IMHO. My 4500W elements gets 7 gallons up to strike temp in about 10 minutes or so. I would use one 5500W in my BK and 5500W in my HLT. You can throw that out the window if you are doing large volumes though.

Its a 3 keggle system with elements as you said in the BK and HLT. I'll be doing 11-12 gallon batches. I am very glad to hear about those heating times!
