UK How to wire a panel transformer

Jamiehasadog · Apr 17, 2021

I have a panel transformer with the input options of : 415V 220V 0V and output options of 110V. I’m using this so the control panel will run 110V and not 415 or 220. I have a three phase supply and how would I wire this into the transformer and also how do I wire the output. Where does 0V go and what do I use as a neutral for the circuit ? Thanks

The primary and secondary connections should be self explanatory. What is the purpose of this transformer and your involvement.

Panel wiring for work. Just wondering if 0V is used as a neutral through the control circuit ( 0V on secondary) and if I connect up to the primary with one phase (240) do I need to connect any other wires or just live

I don't mean to be negative here but do you understand the principles of an isolating transformer.

It’s okay if you don’t know dude

As Westwood and,
You are modifiying or building a control panel, this means you own the design and become responsible for any future issues.
The questions you ask suggest you don't have the knowledge or experience to carry out this task.

Just from the fact you refer to people as "dude" has answered my question.

Protip - when your opening question is "How do I wire this idiot-proof piece of gear" which you then followed up by implying you have no idea how control circuits work, best not to go for the trifecta by trying to neg the old master of the forum.
