Does the neutral wire actually connect to anything in the Brewzilla (i.e. is there anything that runs on 120V - perhaps the pump.) Since the Brewzilla is from a non-USA company, it's likely that the 220V version uses a 220V pump, and does not actually use the neutral wire on your plug/outlet for anything. If this is the case, you don't need a 4-wire plug when you convert.Thanks DuncB...
If you have any info on what wires go where, that will help a lot - there seem to be more wires involved with the USA setup as it is compared to the 3 wires there...they have only a live, neutral and earth. 220 here involves 2 lives, neutral, ground, etc, etc... As the old saying goes "don't let the smoke out', and I realllly want to stick to that, and I get only 1 chance at it!
This is incorrect. In the USA, houses are fed from a transformer with a 240V secondary winding that is center tapped. The center tap wire is bonded to ground in the service panel for the structure and the neutral bus in the service panel is connected to ground. If you connect to both ends of the source transformer, you get single phase 240V. One wire is 120V relative to ground/neutral, the other wire is also 120V relative to ground/neutral, but of opposite phase. If you connect to one end of the source transformer and the center tap you get 120V relative to ground/neutral. There is no 3-phase involved in 240V service to residences. If you only use 240V in an appliance, you only need three wires - hot 1, hot 2, and ground. If you have both 240V and 120V loads in an appliance, then you need four wires - hot 1, hot 2, neutral, and ground.So six wires go into your plug or do you mean at the socket?
It's because you are on 110V and so need a 3 phase supply to get 220V at the socket. In Europe as you know it's fresh running 220V from the Live neutral and earth supply. But it gets complicated if you want 3 phase in Europe just the same but that gives you 450V which is more industrial but becoming a routine install in new builds as useful for higher rated car chargers.
Correct (usually.) I'm not a motor expert, so I don't fully understand everything in the link below.As far as I'm aware, the difference in Hz will only make motors run fractionally slower... The heating elements and control system ought not be affected...
HiPlease tell more about the "smartPID"!
You order it off the website I linked above, Davide is very helpful when emailed as well. I'd order it for arrival in Europe rather than post to the USA.Sounds amazing - where does one get this item? And it does work on the Brewzilla, right? I have the 3.1.1
I'd like you to connect line 1 and line 2 up to the inputs of an oscilloscope, and take a picture of the two 240V phase traces. The 240V is single phase. Because of the grounded center tap feed transformer, the 240V can be split into two 120V supplies that are 180 deg out of phase with each other, so yes there are two different phase 120V sources available within the service panel. Any given 120V outlet only has a single phase available. The USA system is referred to as "split phase."Just to let everyone know. the US 240V is two phase, not single phase. There are two 110V lines 180 degrees out of phase from each other.
The pump has induction motor so the speed will vary depending on frequenzy. It will work on both 50 and 60 Hz and there is probably even label on the motor telling the performance difference.Correct (usually.) I'm not a motor expert, so I don't fully understand everything in the link below.
