I have a shed that I plan on on using as 'homebase' for electric brewing in the future.
I have about 50 feet of #6 wire ( 4 separate pieces of solid core insulated)running from a 40 amp breaker in the house subpanel through conduit to a 120/240 subpanel in the shed. I currently have 3 circuits in the shed:
#1 20 amp breaker serves a window shaker
#2 20 amp breaker serves 2 ceiling lights and 3 wall receptacles (one of which is a gfi)
#3 is a 30 amp breaker for a 3 prong 30 amp rv outlet
I seldom use the rv receptacle (it was to trouble shoot the ac) and would like to install another breaker and a 240 outlet to run a 3500 watt element mounted in a boil pot.
I am building a 1650 watt 120 volt heat stick now and plan on using it to heat mash and sparge water, and possibly add it to the boil kettle to assist in getting the boil up faster (5 gal batches..may boil larger quantities for bigger IPAs).
With a 40 amp breaker in the subpanel, would there be any problem running both the heatstick and the 3500 watt boil pot at the same time?
With the 3500 watt element drawing about 16 amps, would an inline 20 amp gfi be sufficient?
Thanks for any feedback, this is a great site with tons of info.
For now the heatstick will be controlled with a toggle switch in a weatherproof box, but I'll later make a simple panel or toolbox panel for a PID.
