I am installing a micro-brewery in our barn in France; as you can guess that, means that I am a brewer, not an electrician I did 'fess up to being a DIYer when signing on.
The brewhouse runs on 3-phase, both for the 12kw heating elements and for the pumps. All use a delta configuration i.e. 3 phases, no neutral.
ENEDIS, the national electricity network company has agreed to supplying me with a 36kVA 3-phase supply. I am organising the distribution panel and wiring, once installed our local electrician will give it a check over and then arrange for inspection and a certification check. I am trying to reduce both costs and especially waiting time.
My question is regarding the nature of RCD operation in 3 phase circuit...Bear wih me, here it comes ...
I want to have a RCD dedicated to the brewhouse. The hot liquor tank has a temperature controller, which is itself a low voltage (12V DC) unit. The temperature controller has a 220V AC-12V DC power supply, powered by L1 and N on the supply. It operates a 230V solenoid switch to regulate the power to the heating element.
Finally: Will the presence of a 2A load on L1/N create an imbalance on the phases that will cause the 30ma RCD to trip?
I hope this picture avoids a thousand words :
