I'm building DIY electronics for a 4x4 table.
I have
- 220v hy VFD
- power supply that was wired for 110v (but has no specs so I don't know if it will take 220v)
- Gecko 540
I want to have a main power switch to the enclosure
Is it common to run 2 separate power cables, one 220 for the VFD and one 110 for the control board, and switch them individually?
OR
If I have 4 wire 220 running into the enclosure (hot - hot - neutral - ground) can I switch the 2 hots using a DPST switch and pull 110v from one leg of the hot and the neutral?
(See attached sketch)
