FAQ
Question: Is it possible to connect a 230 V circulator pump to 400 V electrical mains e.g. during pump replacement?
Answer:
Yes, that is possible. To do so, connect one phase and the neutral conductor. The voltage between phase and neutral is 230 V.
If there is no neutral conductor, a new cable must be routed. Such work must only be performed by a qualified electrician.
